-Configuration and Installation of s/qmail
------------------------------------------
-
-HOW TO INSTALL:
-- s/qmail uses D.J.B's slashpackage convention
-  for installing while trying to conserve the
-  standard qmail installations:
-  * untar the sqmail tar file under '/package'
-  * Move to /package/mail/sqmail/sqmail-V.R.F
-  and go on with installation
-- Set up the s/qmail package with the following
-  step-by-step options or simple run (as 'root'):
-  * package/install -- does it all
-
-A) REQUIREMENTS 
-
-1. Compiler & make utilities.
-2. fehQlibs are installed (typically as /usr/local/qlibs)
-3. The directory /package is in place.
-4. Header files and libs for *SSL.
-5. The UCSPI-SSL package to be installed.
-6. Header files and libraries for IDN2 support (optional).
-7. Header files and libraries for LDAP support (optional).
-
-Optional but very useful:
-
-8. The UCSPI-TCP6 package (tcprules, rblsmtpd).
-9. DJB's Daemontools installed and working.
-10. MRTG to display logging.
-
-
-B) CONFIGURATION
-
-1. Configuration is done by means of the 
-   `conf-XX` files in this main directory.
-
-2. Short description:
-
-   conf-break -- the character for VERP addresses [-]
-   conf-cc -- compiler (no change required)
-   conf-delivery -- qmail-start default-delivery
-   conf-djbdns -- DJBNDS libs (not supported yet)
-   conf-groups*) -- s/qmail groups
-   conf-home -- home dir of s/qmail [/var/qmail]
-   conf-idn2 -- include optional path for libidn2
-   conf-ids*) -- Unix ids for s/qmail
-   conf-instances -- QMQ instances to be raised
-   conf-ld -- loader options to be adjusted (for i386; AMD64 default)
-   conf-log -- target dir of s/qmail logs [/var/log]
-   conf-man -- target dir of man pages, usually automatically recognized
-   conf-patrn -- s/qmail paternalism [002]
-   conf-qmq -- QMQ environment settings
-   conf-spawn -- silent concurrency limit [120]
-   conf-split -- depth of s/qmail dirs [23]
-   conf-svcdir -- supervise's directory [/service]
-   conf-ssl -- path to *SSL header files [empty for defaults]
-   conf-ucspissl -- path to UCSPI-SSL dirs
-   conf-users*) -- user names
-
-   Configurations labeled with *) need to be treated together.
-   
-3. Depending on your settings, you may need to 
-   adjust the following:
-
-   a) conf-cc:    Perhaps remove the -DIDN2 option
-                  if libidn2 is not installed.
-                  Other options are: 
-                  -DHIDEVIRTUALUSER
-                  -DDEFERREDBOUNCES
-                  -DSHOWLOG
-                  -DBARELF
-   b) conf-ld:    Adjust architecture of executables.
-                  If you use OpenSSL/LibreSSL from sources outside the
-                  default, you need to include the link path (-L).
-   c) conf-idn2:  Include optional path to 'libidn2'. 
-
-4. s/qmail user settings:
-
-   a) conf-ids:   The UIDs and GIDs
-   b) conf-groups:The s/qmail group names. 
-   c) conf-users: The s/qmail user names.
-
-5. Directories and system interaction:
-
-   a) conf-home
-   b) conf-qlibs 
-   c) conf-ssl
-   d) conf-ucspissl
-   e) conf-log
-   f) conf-man
-   g) conf-svcdir
-
-6. Run-time issues:
-
-   a) conf-break
-   b) conf-patrn
-   c) conf-split
-   d) conf-delivery
-   e) conf-instances (still not working yet)
-   f) conf-qmq (still not uptodate jet) 
-
-
-C) INSTALLATION 
-
-1. Upon configuration and verification
-   to meet requirements, simply do
-
-   package/install
-
-2. Detail description of installation steps:
-
-   package/dir -- sets up the directories
-   package/ids -- sets up the s/qmail users
-   package/ucspissl -- hooks up the required sources and libs with package ucspi-ssl
-   package/compile -- compiles the sources
-   package/upgrade -- potentially does the upgrade
-   package/legacy -- installs the binaries in the qmail directory
-   package/man -- installes the man pages
-
-   All done be package/install. Additional (initial) settings:
-
-   package/control -- populates the mininmal required control files for running
-   package/sslenv -- sets up the SSL/TLS environments together with X.509 certs and key files (from ucspi-ssl)
-   package/service -- sets up the run script for daemontools' /service and additionally the logging
-   package/scripts setup optional, undocumented and unmaintained scripts
-   package/run -- touches qmail/alias/ files and sets default-delivery
-
-3. Installation on OpenBSD
-
-  s/qmail should be placed under
-    /usr/local/qmail
-  -- or --
-   mount -u -o suid /var
-
-4. Upgrade from an existing Qmail
-
-  s/qmail will keep your current qmail setup (except for the binaries):
-
-  * Make sure, to have ucspi-ssl installed
-  * Extract s/qmail under /package
-  * cd /package/mail/sqmail-V.R.F
-  * package/ucspissl
-  * package/compile
-  * package/legacy
-  * package/man
-  * package/upgrade
-
-  In case your qmail installation is out of default, use the conf-* settings (ie. ids).
-  Make sure, that your qmail 'todo' queue and the 'tcpto' table is empty (qmail-tcpto, qmail-tcpok).
-
-  You need to change the port separator in the control files from ':' to ';' - if applicable.
-
-5. Deinstallation and re-do installation
-
-   Within s/qmail's installation directory (where this file resides)
-   simply do:
-
-   rm -r compile 
-
-   Alternatively, you can do
-
-   cd compile; make clean
-
-   To re-install man-pages:
-  
-   cd man; rm *.gz; make clean
-    
-   Now you can continue with re-installation. 
-
-6. Additional compile-time options
-
-   conf-cc allows you to customize compilation for the following needs:
-
-   - Internationalization: Include the option -IDN2.
-     Be sure, to have IDN2 installed prior of compilation.
-
-   - Virtual user obfuscation: Include the option -DHIDEVRITUALUSER.
-     Now, the virtual user extension is excluded in the mail header
-     for the displayed addresses. Vpopmail, however, requires this!
-
-  -  Delayed bounces: Use -DDEFERREDBOUNCES.
-     Now, qmail-remote will retry mail delivery even for not DNS
-     resolveable host names and IP addresses until queue lifetime
-     expires.
-
-  -  DKIM private key names used for signing are shown
-     in qmail-remote logs via option -DSHOWLOG.
-
-  -  Strict RF 5821 conformance for <CRLF.CRLF> can be 
-     relaxed by -DBARELF (=> 'SMTP smuggling' still not possible).
-
-   - Check conf-cc for more restrictive settings.
-
-
-D) DKIM CONFIGURATION
-
-1. Key generation:
-   You need to generate a public/private key pair.
-   The private key is used to sign outgoing mails.
-   The public key needs to be in the DNS as DKIM TXT record.
-   Use the script mkdkimkey (after make in that directory)
-   to generate RSA/Ed25519 key pairs in the required format.
-
-2. Signing operation:
-   Populate the private key in the directory
-     ssl/domainkeys/<domain>
-   and symlink it as 'default' (= selector).
-   Key roll-over is easily supported with different selectors.
-   Create
-     control/dkimdomains
-   with the entry '=:' defaulting to your domain/MTA.
-   Several domain entries with different attributes can be used.
-   Upon raising the file 'control/dkimdomains' all outgoing
-   emails will be automatically DKIM signed in case the
-   sending domains are listed therein.
-
-3. Verification operation:
-   Use qmail-dkverify as paramater in your 'smtpd.tcpd' file:
-   :allow,QMAILQUEUE="bin/qmail-qmail-dkverify"
-   Usually, qmail-dkverify works in annotation mode only, thus
-   simply inlcudes a header for further message processing like this:
-     X-Authentication-Results: piplus.fehcom.de; dkim=pass; bigchief.fehcom.de
-
-   If you however set 'DKIM=+' as environment variable, mails
-   failing DKIM verification (wrong signature) will be rejected upon receipt.
-   This is not recommended, since mails may be subject of re-writing
-   by mail-scanning MTAs.
-
-Note: DKIM is inappropriate with QMTP(S) delivery. 
-
-E) MISCELLANEOUS
-
-1. s/qmail comes with a full set of updated man-pages.
-
-2. s/qmail supports SPF and SRS natively without additional libs.
-
-3. qmail-postgrey requires postgrey: [https://postgrey.schweikert.ch/]
-
-4. Further documentation can be found in ./doc
-
-5. Convenience files can be found in ./etc
-
-6. Samples for control files are provided in ./ctl
-
-7. Additional scripts are located in ./scripts
-
-8. Start-scripts (for Daemontools) reside in ./service

-.TH s/qmail: addresses 5
-.SH "NAME"
-addresses \- formats for Internet mail addresses
-.SH "INTRODUCTION"
-A
-.B mail address
-is a string of characters containing @.
-
-Every mail address has a
-.B local part
-and a
-.B domain part\fR.
-The domain part is everything after the final @.
-The local part is everything before.
-
-For example, the mail addresses
-
-.EX
-   God@heaven.af.mil
-   @heaven.af.mil
-   @at@@heaven.af.mil
-.EE
-
-all have domain part
-.BR heaven.af.mil .
-The local parts are
-.BR God ,
-empty,
-and
-.BR @at@ .
-
-Some domains have owners.
-It is up to the owner of
-.B heaven.af.mil
-to say how mail messages will be delivered to addresses with domain part
-.BR heaven.af.mil .
-
-The domain part of an address is interpreted without regard to case, so
-
-.EX
-   God@heaven.af.mil
-.br
-   God@HEAVEN.AF.MIL
-.br
-   God@Heaven.AF.Mil
-.EE
-
-all refer to the same domain.
-
-There is one exceptional address that does not contain an @:
-namely, the empty string.
-The empty string cannot be used as a recipient address.
-It can be used as a sender address so that
-the real sender doesn't receive bounces.
-.SH "QMAIL EXTENSIONS"
-The
-.B qmail
-system allows several further types of addresses in mail envelopes.
-
-First, an envelope recipient address without an @ is interpreted as being at
-.IR envnoathost .
-For example, if
-.I envnoathost
-is
-.BR heaven.af.mil ,
-the address
-.B God
-will be rewritten as
-.BR God@heaven.af.mil .
-
-Second, the address
-.B #@[]
-is used as an envelope sender address for double bounces.
-
-Third, envelope sender addresses of the form
-.I pre\fB@\fIhost\fB-@[]
-are used to support variable envelope return paths (VERPs).
-.B qmail-send
-will rewrite 
-.I pre\fB@\fIhost\fB-@[]
-as
-.I prerecip\fB=\fIdomain\fB@\fIhost
-for deliveries to
-.IR recip\fB@\fIdomain .
-Bounces directly from
-.B qmail-send
-will come back to
-.IR pre\fB@\fIhost .
-.SH "CHOOSING MAIL ADDRESSES"
-Here are some suggestions on choosing mail addresses for the Internet.
-
-Do not use non-ASCII characters.
-Under RFC 822 and RFC 821,
-these characters cannot be used in mail headers or in SMTP commands.
-In practice, they are regularly corrupted.
-
-Do not use ASCII control characters.
-NUL is regularly corrupted.
-CR and LF cannot be used in some combinations
-and are corrupted in all.
-None of these characters are usable on business cards.
-
-Avoid spaces and the characters
-
-.EX
-   \\"<>()[],;:
-.EE
-
-These all require quoting in mail headers and in SMTP.
-Many existing mail programs do not handle quoting properly.
-
-Do not use @ in a local part.
-@ requires quoting in mail headers and in SMTP.
-Many programs incorrectly look for the first @,
-rather than the last @,
-to find the domain part of an address.
-
-In a local part,
-do not use two consecutive dots, a dot at the beginning, or a dot at the end.
-Any of these would require quoting in mail headers.
-
-Do not use an empty local part; it cannot appear in SMTP commands.
-
-Avoid local parts longer than 64 characters.
-
-Be wary of uppercase letters in local parts.
-Some mail programs (and users!) will incorrectly convert
-.B God@heaven.af.mil
-to
-.BR god@heaven.af.mil .
-
-Be wary of the following characters:
-
-.EX
-   $&!#~`'^*|{}
-.EE
-
-Some users will not know
-how to feed these characters safely to their mail programs.
-
-In domain names, stick to letters, digits, dash, and dot.
-One popular DNS resolver has,
-under the banner of security,
-recently begun destroying domain names
-that contain certain other characters,
-including underscore.
-Exception: A dotted-decimal IP address in brackets,
-such as
-.BR [127.0.0.1] ,
-identifies a domain owned by whoever owns the host at that IP address,
-and can be used safely.
-
-In a domain name,
-do not use two consecutive dots,
-a dot at the beginning,
-or a dot at the end.
-This means that,
-when a domain name is broken down into components separated by dots,
-there are no empty components.
-
-Always use at least one dot in a domain name.
-If you own the
-.B mil
-domain,
-don't bother using the address
-.BR root@mil ;
-most users will be unable to send messages to that address.
-Same for the root domain.
-
-Avoid domain names longer than 64 characters.
-.SH "ENCODED ADDRESSES IN SMTP COMMANDS"
-RFC 821 defines an encoding of mail addresses in SMTP.
-For example, the addresses
-
-.EX
-   God@heaven.af.mil
-.br
-   a"quote@heaven.af.mil
-.br
-   The Almighty.One@heaven.af.mil
-.EE
-
-could be encoded in RCPT commands as
-
-.EX
-   RCPT TO:<God@heaven.af.mil>
-.br
-   RCPT TO:<a\\"quote@heaven.af.mil>
-.br
-   RCPT TO:<The\\ Almighty.One@heaven.af.mil>
-.EE
-
-There are several restrictions in RFC 821
-on the mail addresses that can be used over SMTP.
-Non-ASCII characters are prohibited.
-The local part must not be empty.
-The domain part must be a sequence of elements separated by dots,
-where each element is either a component,
-a sequence of digits preceded by #,
-or a dotted-decimal IP address surrounded by brackets.
-The only allowable characters in components are
-letters, digits, and dashes.
-Every component must (believe it or not)
-have at least three characters;
-the first character must be a letter;
-the last character must not be a hyphen.
-.SH "ENCODED ADDRESSES IN MAIL HEADERS"
-RFC 822 defines an encoding of mail addresses
-in certain header fields in a mail message.
-For example, the addresses
-
-.EX
-   God@heaven.af.mil
-.br
-   a"quote@heaven.af.mil
-.br
-   The Almighty.One@heaven.af.mil
-.EE
-
-could be encoded in a

-International Atomic Time, TAI,
-is the fundamental unit for time measurements.
-TAI has one label for every second of real time,
-without complications such as leap seconds.
-
-A
-struct datetime
-variable,
-such as
-.IR dt ,
-stores a TAI label.
-.I dt\fB.year
-is the year number minus 1900;
-.I dt\fB.mon
-is the month number, from 0 (January) through 11 (December);
-.I dt\fB.mday
-is the day of the month, from 1 through 31;
-.I dt\fB.hour
-is the hour, from 0 through 23;
-.I dt\fB.min
-is the minute, from 0 through 59;
-.I dt\fB.sec
-is the second, from 0 through 59;
-.I dt\fB.wday
-is the day of the week, from 0 (Sunday) through 6 (Saturday);
-.I dt\fB.yday
-is the day of the year, from 0 through 365.
-
-The
-.B datetime
-library supports more convenient TAI manipulation with
-the datetime_sec type.
-A datetime_sec value, such as
-.IR t ,
-is an integer referring to the
-.IR t th
-second after the beginning of 1970 TAI.
-The first second of 1970 TAI was 0;
-the next second was 1;
-the last second of 1969 TAI was -1.
-The difference between two datetime_sec values is a number
-of real-time seconds.
-
-.B datetime_tai
-converts a datetime_sec to a TAI label.
-
-.B datetime_untai
-reads a TAI label
-(specifically
-.IR dt\fB.year ,
-.IR dt\fB.mon ,
-.IR dt\fB.mday ,
-.IR dt\fB.hour ,

-.TH s/qmail: dot-qmail 5
-.SH NAME
-dot-qmail \- control the delivery of mail messages
-.SH DESCRIPTION
-Normally the
-.B qmail-local
-program delivers each incoming message to your system mailbox,
-.IR homedir\fB/Mailbox ,
-where
-.I homedir
-is your home directory.
-
-It can instead
-write the mail to a different file or directory,
-forward it to another address,
-distribute it to a mailing list,
-or even execute programs,
-all under your control.
-.SH "THE QMAIL FILE"
-To change
-.BR qmail-local 's
-behavior, set up a
-.B .qmail
-file in your home directory.
-
-.B .qmail
-contains one or more lines.
-Each line is a delivery instruction.
-.B qmail-local
-follows each instruction in turn.
-There are five types of delivery instructions:
-(1) comment; (2) program; (3) forward; (4) mbox; (5) maildir.
-.TP 5
-(1)
-A comment line begins with a number sign:
-
-.EX
-     # this is a comment
-.EE
-
-.B qmail-local
-ignores the line.
-.TP 5
-(2)
-A program line begins with a vertical bar:
-
-.EX
-     |preline /usr/ucb/vacation djb
-.EE
-
-.B qmail-local
-takes the rest of the line as a command to supply to
-.BR sh .
-See
-.B qmail-command(8)
-for further information.
-.TP 5
-(3)
-A forward line begins with an ampersand:
-
-.EX
-     &me@new.job.com
-.EE
-
-.B qmail-local
-takes the rest of the line as a mail address;
-it uses
-.B qmail-queue
-to forward the message to that address.
-The address must contain a fully qualified domain name;
-it must not contain extra spaces, angle brackets, or comments:
-
-.EX
-     # the following examples are WRONG
-.br
-     &me@new
-.br
-     &<me@new.job.com>
-.br
-     & me@new.job.com
-.br
-     &me@new.job.com (New Address)
-.EE
-
-If the address begins with a letter or number,
-you may leave out the ampersand:
-
-.EX
-     me@new.job.com
-.EE
-
-Note that
-.B qmail-local
-omits its new
-.B Return-Path
-line when forwarding messages.
-.TP 5
-(4)
-An 
-.I mbox
-line begins with a slash or dot,
-and does not end with a slash:
-
-.EX
-     /home/djb/Mailbox.sos
-.EE
-
-.B qmail-local
-takes the entire line as a filename.
-It appends the mail message to that file,
-using
-.BR flock -style
-file locking if possible.
-.B qmail-local
-stores the mail message in
-.I mbox
-format, as described in
-.BR mbox(5) .
-
-.B WARNING:
-On many systems,
-anyone who can read a file can
-.B flock
-it, and thus hold up
-.BR qmail-local 's
-delivery forever.
-Do not deliver mail to a publicly accessible file!
-
-If
-.B qmail-local
-is able to lock the file, but has trouble writing to it
-(because, for example, the disk is full),
-it will truncate the file back to its original length.
-However, it cannot prevent mailbox corruption if the system
-crashes during delivery.
-.TP 5
-(5)
-A
-.I maildir
-line begins with a slash or dot,
-and ends with a slash:
-
-.EX
-     /home/djb/Maildir/
-.EE
-
-.B qmail-local
-takes the entire line as the name of a directory in
-.I maildir
-format.
-It reliably stores the incoming message in that directory.
-See
-.B maildir(5)
-for more details.
-.PP
-If
-.B .qmail
-has the execute bit set,
-it must not contain any
-program lines,
-.I mbox
-lines,
-or
-.I maildir
-lines.
-If
-.B qmail-local
-sees any such lines,
-it will stop and indicate a temporary failure.
-
-If
-.B .qmail
-is completely empty (0 bytes long), or does not exist,
-.B qmail-local
-follows the
-.I defaultdelivery
-instructions set by your system administrator;
-normally
-.I defaultdelivery
-is
-.BR ./Mailbox ,
-so
-.B qmail-local
-appends the mail message to
-.B Mailbox
-in
-.I mbox
-format.
-
-.B .qmail
-may contain extra spaces and tabs at the end of a line.
-Blank lines are allowed, but not for the first line of
-.BR .qmail .
-
-If
-.B .qmail
-is world-writable or group-writable,
-.B qmail-local
-stops and indicates a temporary failure.
-.SH "SAFE QMAIL EDITING"
-Incoming messages can arrive at any moment.
-If you want to safely edit your
-.B .qmail
-file, first set the sticky bit on your home directory:
-
-.EX
-     chmod +t $HOME
-.EE
-
-.B qmail-local
-will temporarily defer delivery of any message to you
-if your home directory is sticky
-(or group-writable or other-writable,
-which should never happen).
-Make sure to
-
-.EX
-     chmod -t $HOME
-.EE
-
-when you are done!
-It's a good idea to test your new
-.B .qmail
-file as follows:
-
-.EX
-     qmail-local -n $USER ~ $USER '' '' '' '' ./Mailbox
-.EE
-
-.SH "EXTENSION ADDRESSES"
-In the
-.B qmail
-system,
-you control all local addresses of the form
-.IR user\fBBREAK\fIanything ,
-as well as the address
-.I user
-itself,
-where
-.I user
-is your account name.
-Delivery to
-.I user\fBBREAK\fIanything
-is controlled by the file
-.IR homedir/\fB.qmail\-\fIanything .
-(These rules may be changed by the system administrator;
-see
-.BR qmail-users (5).)
-
-The
-.B alias
-user controls all other addresses.
-Delivery to
-.I local
-is controlled by the file
-.IR homedir/\fB.qmail\-\fIlocal ,
-where
-.I homedir
-is
-.BR alias 's
-home directory.
-
-In the following description,
-.B qmail-local
-is handling a message addressed to
-.IR local@domain ,
-where
-.I local
-is controlled by
-.BR .qmail\-\fIext .
-Here is what it does.
-
-If
-.B .qmail\-\fIext
-is completely empty,
-.B qmail-local
-follows the
-.I defaultdelivery
-instructions set by your system administrator.
-
-If
-.B .qmail\-\fIext
-doesn't exist,
-.B qmail-local
-will try some default
-.B .qmail
-files.
-For example,
-if
-.I ext
-is
-.BR foo-bar ,
-.B qmail-local
-will try first
-.BR .qmail-foo-bar ,
-then
-.BR .qmail-foo-default ,
-and finally
-.BR .qmail-default .
-If none of these exist,
-.B qmail-local
-will bounce the message.
-(Exception: for the basic
-.I user
-address,
-.B qmail-local
-treats a nonexistent
-.B .qmail
-the same as an empty
-.BR .qmail .)
-
-.B WARNING:
-For security,
-.B qmail-local
-replaces any dots in
-.I ext
-with colons before checking
-.BR .qmail\-\fIext .
-For convenience,
-.B qmail-local
-converts any uppercase letters in
-.I ext
-to lowercase.
-
-When
-.B qmail-local
-forwards a message as instructed in
-.B .qmail\-\fIext
-(or
-.BR .qmail-default ),
-it checks whether
-.B .qmail\-\fIext\fB-owner\fP
-exists.
-If so,
-it uses
-.I local\fB-owner@\fIdomain
-as the envelope sender for the forwarded message.
-Otherwise it retains the envelope sender of the original message.
-Exception:
-.B qmail-local
-always retains the original envelope sender
-if it is the empty address or
-.BR #@[] ,
-i.e., if this is a bounce message.
-
-.B qmail-local
-also supports
-.B variable envelope return paths
-(VERPs):
-if
-.B .qmail\-\fIext\fB-owner\fP
-and
-.B .qmail\-\fIext\fB-owner-default\fP
-both exist, it uses
-.I local\fB\-owner\-@\fIdomain\fB-@[]
-as the envelope sender.
-This will cause a recipient
-.I recip\fB@\fIreciphost
-to see an envelope sender of
-.IR local\fB\-owner\-\fIrecip\fB=\fIreciphost\fB@\fIdomain .
-.SH "ERROR HANDLING"
-If a delivery instruction fails,
-.B qmail-local
-stops immediately and reports failure.
-.B qmail-local
-handles forwarding after all other instructions,
-so any error in another type of delivery will prevent all forwarding.
-
-If a program returns exit code 99,
-.B qmail-local
-ignores all succeeding lines in
-.BR .qmail ,
-but it still pays attention to previous forward lines.
-
-To set up independent instructions,
-where a temporary or permanent failure in one instruction
-does not affect the others,
-move each instruction into a separate
-.B .qmail\-\fIext
-file, and set up a central
-.B .qmail
-file that forwards to all of the
-.BR .qmail\-\fIext s.
-Note that
-.B qmail-local
-can handle any number of forward lines simultaneously.

-.TH s/qmail: envelopes 5
-.SH "NAME"
-envelopes \- sender/recipient lists attached to messages
-.SH "INTRODUCTION"
-Electronic mail messages are delivered in
-.IR envelopes .
-
-An envelope lists a
-.I sender
-and one or more
-.IR recipients .
-Usually these
-envelope addresses are the same
-as the addresses listed in the message header:
-
-.EX
-   (envelope) from djb to root
-.br
-   From: djb
-.br
-   To: root
-.EE
-
-In more complicated situations, though,
-the envelope addresses may differ from the header addresses.
-.SH "ENVELOPE EXAMPLES"
-When a message is delivered to
-several people at different locations,
-it is first photocopied
-and placed into several envelopes:
-
-.EX
-   (envelope) from djb to root
-.br
-   From: djb                          Copy #1 of message
-.br
-   To: root, god@brl.mil
-.EE
-
-.EX
-   (envelope) from djb to god@brl.mil
-.br
-   From: djb                          Copy #2 of message
-.br
-   To: root, god@brl.mil
-.EE
-
-When a message is delivered
-to several people at the same location,
-the sender doesn't have to photocopy it.
-He can instead stuff it into
-one envelope with several addresses;
-the recipients will make the photocopy:
-
-.EX
-   (envelope) from djb to god@brl.mil, angel@brl.mil
-.br
-   From: djb
-.br
-   To: god@brl.mil, angel@brl.mil, joe, frde
-.EE
-
-Bounced mail is sent back to the envelope sender address.
-The bounced mail doesn't list an envelope sender,
-so bounce loops are impossible:
-
-.EX
-   (envelope) from <> to djb
-.br
-   From: MAILER-DAEMON
-.br
-   To: djb
-.br
-   Subject: unknown user frde
-.EE
-
-The recipient of a message may make another copy
-and forward it in a new envelope:
-
-.EX
-   (envelope) from djb to joe
-.br
-   From: djb                          Original message
-.br
-   To: joe
-.EE
-
-.EX
-   (envelope) from joe to fred
-.br
-   From: djb                          Forwarded message
-.br
-   To: joe
-.EE
-
-A mailing list works almost the same way:
-
-.EX
-   (envelope) from djb to sos-list
-.br
-   From: djb                          Original message
-.br
-   To: sos-list
-.EE
-
-.EX
-   (envelope) from sos-owner to god@brl.mil
-.br
-   From: djb                          Forwarded message
-.br
-   To: sos-list                       to recipient #1
-.EE
-
-.EX
-   (envelope) from sos-owner to frde
-.br
-   From: djb                          Forwarded message
-.br
-   To: sos-list                       to recipient #2
-.EE
-
-Notice that the mailing list is set up
-to replace the envelope sender with something new,
-.BR sos-owner .
-So bounces will come back to
-.BR sos-owner :
-
-.EX
-   (envelope) from <> to sos-owner
-.br
-   From: MAILER-DAEMON
-.br
-   To: sos-owner
-.br
-   Subject: unknown user frde
-.EE
-
-It's a good idea to set up an extra address,
-.BR sos-owner ,
-like this:
-the original envelope sender (\fBdjb\fP)
-has no way to fix bad
-.B sos-list
-addresses,
-and of course bounces must not be sent to 
-.B sos-list
-itself.
-.SH "HOW ENVELOPE ADDRESSES ARE STORED"
-Envelope sender and envelope recipient addresses
-are transmitted and recorded in several ways.
-
-When a user injects mail through
-.BR qmail-inject ,
-he can supply a
-.B Return-Path
-line or a
-.B \-f
-option for the envelope sender;
-by default the envelope sender is his login name.
-The envelope recipient addresses can be taken
-from the command line or from various header fields,
-depending on the options to
-.BR qmail-inject .
-Similar comments apply to
-.BR sendmail .
-
-When a message is transferred from one machine to another through SMTP,
-the envelope sender is given in a
-.B MAIL FROM
-command,
-the envelope recipients are given in 
-.B RCPT TO
-commands,
-and the message is supplied separately by a 
-.B DATA
-command.
-
-When a message is delivered by
-.B qmail
-to a single local recipient,
-.B qmail-local
-records the recipient in
-.B Delivered-To
-and the envelope sender in
-.BR Return-Path .
-It uses
-.B Delivered-To
-to detect mail forwarding loops.
-
-.B sendmail
-normally records the envelope sender in
-.BR Return-Path .
-It does not record envelope recipient addresses,
-on the theory that they are redundant:
-you received the mail,
-so you must have been one of the envelope recipients.
-
-Note that,
-if the header doesn't have any recipient addresses,
-.B sendmail
-will move envelope recipient addresses back into the header.
-This situation occurs if all addresses were originally listed as
-.BR Bcc ,
-since
-.B Bcc
-is automatically removed.
-When
-.B sendmail
-sees this, it creates a new
-.B Apparently-To
-header field with the envelope recipient addresses.
-This has the strange effect that each blind-carbon-copy recipient will see
-a list of all recipients on the same machine.
-
-When a message is stored in
-.B mbox
-format,
-the envelope sender is recorded at the top of the message
-as a UUCP-style
-.B From
-(no colon) line.
-Note that this line is less reliable than the
-.B Return-Path
-line added by
-.B qmail-local
-or
-.B sendmail\fP.

-.TH s/qmail: forgeries 7
-.SH "NAME"
-forgeries \- how easy it is to forge mail
-.SH "SUMMARY"
-An electronic mail message can easily be forged.
-Almost everything in it,
-including the return address,
-is completely under the control of the sender.
-
-An electronic mail message can be manually traced to its origin
-if (1) all system administrators of intermediate machines
-are both cooperative and competent,
-(2) the sender did not break low-level TCP/IP security,
-and
-(3) all intermediate machines are secure.
-
-Users of
-.I cryptography
-can automatically ensure the integrity and secrecy
-of their mail messages, as long as
-the sending and receiving machines are secure.
-.SH "FORGERIES"
-Like postal mail,
-electronic mail can be created entirely at the whim of the sender.
-.BR From ,
-.BR Sender ,
-.BR Return-Path ,
-and
-.BR Message-ID
-can all contain whatever information the sender wants.
-
-For example, if you inject a message through
-.B sendmail
-or
-.B qmail-inject
-or
-.BR SMTP ,
-you can simply type in a
-.B From
-field.
-In fact,
-.B qmail-inject
-lets you set up
-.BR MAILUSER ,
-.BR MAILHOST ,
-and
-.B MAILNAME
-environment variables
-to produce your desired
-.B From
-field on every message.
-.SH "TRACING FORGERIES"
-Like postal mail,
-electronic mail is postmarked when it is sent.
-Each machine that receives an electronic mail message
-adds a
-.B Received
-line to the top.
-
-A modern
-.B Received
-line contains quite a bit of information.
-In conjunction with the machine's logs,
-it lets a competent system administrator
-determine where the machine received the message from,
-as long as the sender did not break low-level TCP/IP security
-or security on that machine.
-
-Large multi-user machines often come with inadequate logging software.
-Fortunately, a system administrator can easily obtain a copy of a
-931/1413/Ident/TAP server, such as
-.BR pidentd .
-Unfortunately,
-some system administrators fail to do this,
-and are thus unable to figure out which local user
-was responsible for generating a message.
-
-If all intermediate system administrators are competent,
-and the sender did not break machine security or low-level TCP/IP security,
-it is possible to trace a message backwards.
-Unfortunately, some traces are stymied by intermediate system
-administrators who are uncooperative or untrustworthy.
-.SH "CRYPTOGRAPHY"
-The sender of a mail message may place his message into a
-.I cryptographic
-envelope stamped with his seal.
-Strong cryptography guarantees that any two messages with the same seal
-were sent by the same cryptographic entity:
-perhaps a single person, perhaps a group of cooperating people,
-but in any case somebody who knows a secret originally held
-only by the creator of the seal.
-The seal is called a
-.I public key\fR.
-
-Unfortunately, the creator of the seal is often an insecure machine,
-or an untrustworthy central agency,
-but most of the time seals are kept secure.
-
-One popular cryptographic program is
-.BR pgp .

-.SH "NAME"
-maildir \- directory for incoming mail messages
-.SH "INTRODUCTION"
-.I maildir
-is a structure for
-directories of incoming mail messages.
-It solves the reliability problems that plague
-.I mbox
-files and
-.I mh
-folders.
-.SH "RELIABILITY ISSUES"
-A machine may crash while it is delivering a message.
-For both
-.I mbox
-files and
-.I mh
-folders this means that the message will be silently truncated.
-Even worse: for
-.I mbox
-format, if the message is truncated in the middle of a line,
-it will be silently joined to the next message.
-The mail transport agent will try again later to deliver the message,
-but it is unacceptable that a corrupted message should show up at all.
-In
-.IR maildir ,
-every message is guaranteed complete upon delivery.
-
-A machine may have two programs simultaneously delivering mail
-to the same user.
-The
-.I mbox
-and
-.I mh
-formats require the programs to update a single central file.
-If the programs do not use some locking mechanism,
-the central file will be corrupted.
-There are several
-.I mbox
-and
-.I mh
-locking mechanisms,
-none of which work portably and reliably.
-In contrast, in
-.IR maildir ,
-no locks are ever necessary.
-Different delivery processes never touch the same file.
-
-A user may try to delete messages from his mailbox at the same
-moment that the machine delivers a new message.
-For
-.I mbox
-and
-.I mh
-formats, the user's mail-reading program must know
-what locking mechanism the mail-delivery programs use.
-In contrast, in
-.IR maildir ,
-any delivered message
-can be safely updated or deleted by a mail-reading program.
-
-Many sites use Sun's 
-.B Network F\fPa\fBil\fPur\fBe System
-(NFS),
-presumably because the operating system vendor does not offer
-anything else.
-NFS exacerbates all of the above problems.
-Some NFS implementations don't provide
-.B any
-reliable locking mechanism.
-With 
-.I mbox
-and
-.I mh
-formats,
-if two machines deliver mail to the same user,
-or if a user reads mail anywhere except the delivery machine,
-the user's mail is at risk.
-.I maildir
-works without trouble over NFS.
-.SH "THE MAILDIR STRUCTURE"
-A directory in
-.I maildir
-format has three subdirectories,
-all on the same filesystem:
-.BR tmp ,
-.BR new ,
-and
-.BR cur .
-
-Each file in
-.B new
-is a newly delivered mail message.
-The modification time of the file is the delivery date of the message.
-The message is delivered
-.I without
-an extra UUCP-style
-.B From_
-line,
-.I without
-any
-.B >From
-quoting,
-and
-.I without
-an extra blank line at the end.
-The message is normally in RFC 822 format,
-starting with a
-.B Return-Path
-line and a
-.B Delivered-To
-line,
-but it could contain arbitrary binary data.
-It might not even end with a newline.
-
-Files in
-.B cur
-are just like files in
-.BR new .
-The big difference is that files in
-.B cur
-are no longer new mail:
-they have been seen by the user's mail-reading program.
-.SH "HOW A MESSAGE IS DELIVERED"
-The
-.B tmp
-directory is used to ensure reliable delivery,
-as discussed here.
-
-A program delivers a mail message in six steps.
-First, it
-.B chdir()\fPs
-to the
-.I maildir
-directory.
-Second, it 
-.B stat()s
-the name
-.BR tmp/\fItime.pid.host ,
-where
-.I time
-is the number of seconds since the beginning of 1970 GMT,
-.I pid
-is the program's process ID,
-and
-.I host
-is the host name.
-Third, if
-.B stat()
-returned anything other than ENOENT,
-the program sleeps for two seconds, updates
-.IR time ,
-and tries the
-.B stat()
-again, a limited number of times.
-Fourth, the program
-creates
-.BR tmp/\fItime.pid.host .
-Fifth, the program
-.I NFS-writes
-the message to the file.
-Sixth, the program
-.BR link() s
-the file to
-.BR new/\fItime.pid.host .
-At that instant the message has been successfully delivered.
-
-The delivery program is required to start a 24-hour timer before
-creating
-.BR tmp/\fItime.pid.host ,
-and to abort the delivery
-if the timer expires.
-Upon error, timeout, or normal completion,
-the delivery program may attempt to
-.B unlink()
-.BR tmp/\fItime.pid.host .
-
-.I NFS-writing
-means
-(1) as usual, checking the number of bytes returned from each
-.B write()
-call;
-(2) calling
-.B fsync()
-and checking its return value;
-(3) calling
-.B close()
-and checking its return value.
-(Standard NFS implementations handle
-.B fsync()
-incorrectly
-but make up for it by abusing
-.BR close() .)
-.SH "HOW A MESSAGE IS READ"
-A mail reader operates as follows.
-
-It looks through the
-.B new
-directory for new messages.
-Say there is a new message,
-.BR new/\fIunique .
-The reader may freely display the contents of
-.BR new/\fIunique ,
-delete
-.BR new/\fIunique ,
-or rename
-.B new/\fIunique
-as
-.BR cur/\fIunique:info .
-See
-.B http://pobox.com/~djb/proto/maildir.html
-for the meaning of
-.IR info .
-
-The reader is also expected to look through the
-.B tmp
-directory and to clean up any old files found there.
-A file in
-.B tmp
-may be safely removed if it
-has not been accessed in 36 hours.
-
-It is a good idea for readers to skip all filenames in
-.B new
-and
-.B cur
-starting with a dot.
-Other than this, readers should not attempt to parse filenames.
-.SH "ENVIRONMENT VARIABLES"
-Mail readers supporting
-.I maildir
-use the
-.B MAILDIR
-environment variable
-as the name of the user's primary mail directory.

-.TH s/qmail: mbox 5
-.SH "NAME"
-mbox \- file containing mail messages
-.SH "INTRODUCTION"
-The most common format for storage of mail messages is
-.I mbox
-format.
-An
-.I mbox
-is a single file containing zero or more mail messages.
-.SH "MESSAGE FORMAT"
-A message encoded in
-.I mbox
-format begins with a
-.B From_
-line, continues with a series of
-.B \fRnon-\fBFrom_
-lines,
-and ends with a blank line.
-A
-.B From_
-line means any line that begins with the characters
-F, r, o, m, space:
-
-.EX
-     From god@heaven.af.mil Sat Jan  3 01:05:34 1996
-.br
-     Return-Path: <god@heaven.af.mil>
-.br
-     Delivered-To: djb@silverton.berkeley.edu
-.br
-     Date: 3 Jan 1996 01:05:34 -0000
-.br
-     From: God <god@heaven.af.mil>
-.br
-     To: djb@silverton.berkeley.edu (D. J. Bernstein)
-.br
-
-.br
-     How's that mail system project coming along?
-.br
-
-.EE
-
-The final line is a completely blank line (no spaces or tabs).
-Notice that blank lines may also appear elsewhere in the message.
-
-The
-.B From_
-line always looks like
-.B From
-.I envsender
-.I date
-.IR moreinfo .
-.I envsender
-is one word, without spaces or tabs;
-it is usually the envelope sender of the message.
-.I date
-is the delivery date of the message.
-It always contains exactly 24 characters in
-.B asctime
-format.
-.I moreinfo
-is optional; it may contain arbitrary information.
-
-Between the
-.B From_
-line and the blank line is a message in RFC 822 format,
-as described in
-.BR qmail-header(5) ,
-subject to
-.B >From quoting
-as described below.
-.SH "HOW A MESSAGE IS DELIVERED"
-Here is how a program appends a message to an
-.I mbox
-file.
-
-It first creates a
-.B From_
-line given the message's envelope sender and the current date.
-If the envelope sender is empty (i.e., if this is a bounce message),
-the program uses
-.B MAILER-DAEMON
-instead.
-If the envelope sender contains spaces, tabs, or newlines,
-the program replaces them with hyphens.
-
-The program then copies the message, applying
-.B >From quoting
-to each line.
-.B >From quoting
-ensures that the resulting lines are not
-.B From_
-lines:
-the program prepends a
-.B >
-to any
-.B From_
-line,
-.B >From_
-line,
-.B >>From_
-line,
-.B >>>From_
-line,
-etc.
-
-Finally the program appends a blank line to the message.
-If the last line of the message was a partial line,
-it writes two newlines;
-otherwise it writes one.
-.SH "HOW A MESSAGE IS READ"
-A reader scans through an
-.I mbox
-file looking for
-.B From_
-lines.
-Any
-.B From_
-line marks the beginning of a message.
-The reader should not attempt to take advantage of the fact that every
-.B From_
-line (past the beginning of the file)
-is preceded by a blank line.
-
-Once the reader finds a message,
-it extracts a (possibly corrupted) envelope sender
-and delivery date out of the
-.B From_
-line.
-It then reads until the next
-.B From_
-line or end of file, whichever comes first.
-It strips off the final blank line
-and
-deletes the
-quoting of
-.B >From_
-lines and
-.B >>From_
-lines and so on.
-The result is an RFC 822 message.
-.SH "COMMON MBOX VARIANTS"
-There are many variants of
-.I mbox
-format.
-The variant described above is
-.I mboxrd
-format, popularized by Rahul Dhesi in June 1995.
-
-The original
-.I mboxo
-format quotes only
-.B From_
-lines, not
-.B >From_
-lines.
-As a result it is impossible to tell whether
-
-.EX
-     From: djb@silverton.berkeley.edu (D. J. Bernstein)
-.br
-     To: god@heaven.af.mil
-.br
-
-.br
-     >From now through August I'll be doing beta testing.
-.br
-     Thanks for your interest.
-.EE
-
-was quoted in the original message.
-An
-.I mboxrd
-reader will always strip off the quoting.
-
-.I mboxcl
-format is like
-.I mboxo
-format, but includes a Content-Length field with the 
-number of bytes in the message.
-.I mboxcl2
-format is like
-.I mboxcl
-but has no
-.B >From
-quoting.
-These formats are used by SVR4 mailers.
-.I mboxcl2
-cannot be read safely by
-.I mboxrd
-readers.
-.SH "UNSPECIFIED DETAILS"
-There are many locking mechanisms for
-.I mbox
-files.
-.B qmail-local
-always uses
-.B flock
-on systems that have it, otherwise
-.BR lockf .
-
-The delivery date in a
-.B From_
-line does not specify a time zone.
-.B qmail-local
-always creates the delivery date in GMT
-so that 
-.I mbox
-files can be safely transported from one time zone to another.
-
-If the mtime on a nonempty 
-.I mbox
-file is greater than the atime,
-the file has new mail.
-If the mtime is smaller than the atime,
-the new mail has been read.
-If the atime equals the mtime,
-there is no way to tell whether the file has new mail,
-since
-.B qmail-local
-takes much less than a second to run.
-One solution is for a mail reader to artificially set the
-atime to the mtime plus 1.
-Then the file has new mail if and only if the atime is
-less than or equal to the mtime.
-
-Some mail readers place
-.B Status
-fields in each message to indicate which messages have been read.

-.SH NAME
-newaliases \- create a forwarding database from /etc/aliases
-.SH SYNOPSIS
-.B newaliases
-.SH DESCRIPTION
-.B newaliases
-reads a table of
-sendmail-style
-forwarding instructions from
-.B /etc/aliases
-and converts them into a forwarding database in
-.BR /etc/aliases.cdb .
-The forwarding database can be used by
-.BR fastforward .
-
-For safety,
-.B newaliases
-writes the forwarding database to
-.B /etc/aliases.tmp
-and then moves
-.B /etc/aliases.tmp
-to
-.BR /etc/aliases.cdb .
-If there is a problem creating
-.BR /etc/aliases.tmp ,
-.B newaliases
-complains and leaves
-.B /etc/aliases.cdb
-alone.
-Deliveries can continue using
-.B /etc/aliases.cdb
-in the meantime.
-
-.B newaliases
-always creates
-.B /etc/aliases.cdb
-world-readable.
-
-.B newaliases
-makes no attempt to protect against
-simultaneous updates of
-.BR /etc/aliases.cdb .
-.SH "INSTRUCTION FORMAT"
-.B newaliases
-imitates
-sendmail's
-handling of
-.BR /etc/aliases .
-For example,
-
-.EX
-   root: alice, bill
-.EE
-
-says that mail for
-.B root
-should be forwarded to
-.B alice
-and
-.BR bill .
-
-.B COMPATIBILITY WARNING:
-.B newaliases
-does not support file deliveries.
-You can use the file delivery mechanism described in
-.B dot-qmail(5)
-instead.
-.SH "SIMPLE ALIASES"
-The simplest type of forwarding instruction
-is a line of the form
-
-.EX
-   alias: recip
-.EE
-
-Any message sent to
-.I alias
-will be forwarded to the recipient address
-.IR recip .
-Addresses are compared to
-.I alias
-without regard to case.
-
-Forwarding instructions are cumulative.
-If
-.I recip
-is itself an alias,
-messages to
-.I alias
-will be forwarded the same way as
-messages to
-.IR recip .
-For example, with the following instructions,
-messages to
-.B postmaster@heaven.af.mil
-or
-.B root@heaven.af.mil
-will be delivered to Bob:
-
-.EX
-   postmaster@heaven.af.mil: bob@heaven.af.mil
-.EE
-.br
-.EX
-   root@heaven.af.mil: postmaster@heaven.af.mil
-.EE
-
-.B COMPATIBILITY WARNING:
-With
-sendmail,
-entries in
-.B /etc/aliases
-can override usernames.
-With
-.BR s/qmail ,
-if you install
-.B fastforward
-in
-.BR ~alias/.qmail-default ,
-it will not see addresses that are controlled by other users.
-See
-.BR qmail-getpw (8).
-To change this, see
-.BR qmail-users (5).
-
-.B COMPATIBILITY WARNING:
-Various versions of
-sendmail
-do various strange things with circular alias definitions.
-See
-.BR setforward (1)
-for details on
-.BR fastforward 's
-behavior.
-
-.B COMPATIBILITY WARNING:
-If there are several forwarding instructions for a single
-.IR alias ,
-sendmail
-will complain;
-.B fastforward
-will silently use the first instruction.
-.SH "WILDCARDS"
-.I alias
-can have the form
-.I user@host.dom
-for one user at one host,
-.I @host.dom
-for all users at one host, or
-.I user
-for one user at all hosts.
-
-.B COMPATIBILITY WARNING:
-sendmail
-supports only
-.IR user ;
-it does not support per-host aliases.
-It accepts
-.I user@host.dom
-if
-.I host.dom
-is a local host,
-but it then treats it the same way as
-.IR user ,
-applying to all local hosts and virtual domains.
-.SH "ADDRESS FORMATS"
-Addresses in
-.B /etc/aliases
-are parsed the same way as addresses in RFC 822 message headers.
-Parenthesized comments and bracketed addresses are permitted:
-
-.EX
-   root: bob (Bob, the postmaster)
-   joe: Joe Shmoe <shmoe@heaven.af.mil>
-.EE
-
-Addresses with special characters must be quoted:
-
-.EX
-   fred: "spaced out mailbox"@heaven.af.mil
-.EE
-
-Address groups are not permitted,
-since colons have a different use in
-.BR /etc/aliases .
-
-Any recipient address without a fully qualified domain name is
-fed through the
-.BR defaulthost ,
-.BR defaultdomain ,
-and
-.B plusdomain
-mechanisms described in
-.BR qmail-header (5).
-
-.B COMPATIBILITY WARNING:
-sendmail's
-handling of quotes and backslashes violates RFC 821 and RFC 822,
-and is not supported by
-.BR newaliases .
-The
-.B qmail-local
-delivery mechanism
-lets each user manage several addresses,
-so there is no need for a special syntax to get around forwarding.
-.SH "MULTIPLE RECIPIENTS"
-An instruction may list more than one recipient address:
-
-.EX
-   alias: recip1, recip2, recip3
-.EE
-
-Any message sent to
-.I alias
-will be forwarded to all of the addresses.
-
-A forwarding instruction may be split across several lines.
-Each line past the first must either (1) begin with space or tab
-or (2) be empty:
-
-.EX
-   hostmaster:
-.EE
-.br
-.EX
-      fred,
-.EE
-.br
-.EX
-      joe
-.EE
-
-.B COMPATIBILITY WARNING:
-sendmail
-requires the colon to be on the first line
-of a multi-line forwarding instruction.
-.B newaliases
-doesn't care whether the colon is present at all.
-
-.B COMPATIBILITY WARNING:
-sendmail
-does not permit blank lines in the middle of continuations.
-This has the undesirable effect that a blank line behaves differently
-from a line containing a single space.
-.SH "COMMENTS"
-Any line in
-.B /etc/aliases
-that begins with # is ignored:
-
-.EX
-   # this is a comment
-.EE
-
-A comment may be split across several lines.
-Each line past the first must either (1) begin with space or tab
-or (2) be empty.
-
-.B COMPATIBILITY WARNING:
-sendmail
-does not permit continuations of comment lines.
-.SH "PROGRAMS"
-If a recipient address does not contain a domain name,
-and begins with a vertical bar,
-.B newaliases
-takes the rest of the address as a program to run:
-
-.EX
-   weather: "|weather-server"
-.EE
-
-.B fastforward
-will run
-.B weather-server
-when a message arrives for
-.BR weather .
-
-.B COMPATIBILITY WARNING:
-Internet addresses can legitimately start with
-a slash or vertical bar.
-.B newaliases
-treats anything with an unquoted @ as an address.
-sendmail appears to have various problems
-coping with these addresses,
-and with commands that contain @ signs.
-
-.B COMPATIBILITY WARNING:
-.B newaliases
-does not allow a vertical bar before double quotes.
-.SH "INCLUDE FILES"
-A recipient address of the form
-.B :include:\fIfile
-means ``every address listed in
-.IR file .''
-(Actually
-.B fastforward
-reads
-.IR file\fB.bin ;
-see
-.BR newinclude (1)
-for further details.)
-
-Note that
-.I file
-is read by
-.BR fastforward ,
-not
-.BR newaliases ,
-so the system administrator does not have to run
-.B newaliases
-every time
-.I file
-changes.
-.I file
-must be world-readable
-and accessible to
-.BR fastforward .
-
-.B COMPATIBILITY WARNING:
-If an
-.B :include:
-file is unreadable or nonexistent,
-sendmail
-skips it;
-.B fastforward
-defers delivery of the message.
-
-.B COMPATIBILITY WARNING:
-sendmail
-does not permit spaces inside the literal text
-.BR :include: .
-.B newaliases
-does.
-
-.B COMPATIBILITY WARNING:
-Versions of
-sendmail
-before V8 did not strip quotes from
-.B :include:
-filenames.
-.SH "ALIAS OWNERS"
-If there is an alias for
-.BR owner-\fIlist ,
-any message forwarded through
-.I list
-will have its envelope sender set to
-.BR owner-\fIlist ,
-so that bounces go back to
-.BR owner-\fIlist .
-
-.B COMPATIBILITY WARNING:
-When an alias includes the same recipient both inside and outside
-a mailing list,
-.B fastforward
-sends the message twice,
-once with each envelope sender.
-sendmail
-sends the message only once;
-its choice of envelope sender for that recipient
-depends on the phase of the moon.

-.SH "NAME"
-qmail-authuser \- user authentication
-.SH "SYNOPSIS"
-.B qmail-authuser
-[
-.I program maildirname
-|
-.I [-s authsocket [-x service=authmethod]]
-]
-.I subprogram [ args ]
-.SH "DESCRIPTION"
-.B qmail-authuser
-is a versatile authentication PAM for SMTP, POP3 and IMAP services
-providing four different operation modes depending on the input 
-of the configuration file
-.I SQMAIL/users/authuser 
-and the given arguments.
-It can be used as substitude for the authentication modules
-.IR checkpassword ,
-.IR cmd5checkpw ,
-.IR checkvpw 
-(vmailmgr),
-and 
-.I vchkpw
-(vpopmail) 
-supporting the same arguments on call.
-.TP 5
-Native mode:
-.B qmail-authuser
-reads
-.I SQMAIL/users/authuser 
-and uses the information as local authentication database.
-.TP 5
-System mode:
-.B qmail-authuser
-accesses the Unix 
-.I /etc/password
-file (or it's shadow companion) as authentication source.
-.TP 5
-Virtual user mode:
-.B qmail-authuser 
-calls either the virtual domain auth handler
-.B vchkpw 
-or 
-.BR checkvpw .
-.TP 5
-Dovecot mode:
-.B qmail-authuser
-queries
-.B dovecot
-as authentication provider.
-.SH "USE CASES"
-.B qmail-authuser
-can be used for 
-.TP 5
-authentication only:
-.B qmail-authuser 
-is called as a PAM typically by
-.B qmail-smtpd 
-and verifies the user's credentials
-(userid/password)
-as given by the client.
-.I subprogram 
-is typically
-.BR true .
-.TP 5 
-mailbox interrogation:
-Called by 
-.B qmail-popup 
-or 
-.BR bincimap-up ,
-upon successfull authentication
-.B qmail-authuser
-switches to the home directory of
-.I userid
-and hands over operations to
-.I program 
-provided as
-.B qmail-pop3d
-or 
-.BR bincimpad .
-
-Note: 
-.I maildirname 
-has to start with \'mail\' or \'mbox\'
-irrespective of case.
-.SH "INTERFACE DESCRIPTION"
-.B qmail-authuser 
-can be called by
-.BR qmail-smtpd , 
-.BR qmail-popup ,
-or
-.B bincimap-up 
-while following the 
-.BR checkpassword 's
-interface specification and enabling 
-LOGIN, PLAIN, and CRAM-MD5 authentication for SMTP
-as well as USER and APOP for POP3 and 
-LOGIN and PLAIN for IMAP.
-
-The information supplied on descriptor 3
-is an \fIauthuser\fR name terminated by \e0,
-a \fIpassword\fR or \fIresponse\fR terminated by \e0,
-and a \fIchallenge\fR for CRAM-MD5 or APOP 
-authentication terminated by \e0.
-There must be at most 512 bytes of data before end of file.
-
-In case
-.I authuser 
-and 
-.I password 
-match,
-.B qmail-authuser
-calls
-.B pathexec
-to run
-.B subprogram
-with the given arguments and perhaps setting up the user environment.
-The use of
-.B program 
-is required and can be expressed as
-.B /bin/true
-or 
-.B /usr/bin/true
-for compliance reasons.
-
-.SH "FILES"
-.I SQMAIL/users/authuser 
-contains pairs of 
-.I authuser 
-and 
-.I password 
-tokens separated by a colon (":"). 
-Both tokens may include white spaces (if supported by the OS) and may
-use special characters for certain actions. The provided 
-.I password
-token should have a significant length (> 2 characters).
-
-Lines starting with the \'#\' sign are regarded as comment.
-Trailing empty spaces in lines are removed prior of evaluation.
-.SH "AUTHUSER"
-The 
-.I authuser
-token is the public part of the identity and
-may include a composit information, typically the 
-.I userid 
-and the 
-.I domain
-respectively, described as
-.IR userid@domain .
-.B qmail-authuser
-may treat both parts independently.
-Domain specific authentication may be considered using the
-.I @domain
-part within the
-.I authuser 
-token. However, as an abbreviation, 
-this may be provided simply as
-.IR @ ,
-telling 
-.B qmail-authuser
-to consider all unspecified authusers solely and transparently 
-as \'virtual users\'.
-On the other hand, the
-.I authuser
-token may be wildcarded as
-.IR * .
-Now, 
-.B qmail-authuser 
-is instructed to query the local Unix system as identity provider.
-
-More specific 
-.I authuser
-tokens have precedence over less specific, irrespectively of their order.
-System mode has precedence over virtual user mode.
-Particular users and domains can be disabled from authentication 
-prepending the name with a \'!\' overruling acceptance:
-.IR !authuser .
-
-Note: Virtual Domain Managers require to include the domain within 
-.I authuser 
-in order to identify the domain the user belongs to.
-.SH "NATIVE MODE"
-.B qmail-authuser
-recalculates the digest using the provided challenge
-and the passwords from
-.IR SQMAIL/users/authuser 
-and compares it with response (2nd parameter). 
-
-If no challenge is provided,
-.B qmail-authuser 
-compares the supplied password with the stored 
-.I password 
-token in 
-.IR SQMAIL/users/authuser .
-Thus,
-.B qmail-authuser 
-can be used as PAM identity provider for 
-PLAIN, LOGIN, CRAM-MD5 and APOP auth methods.
-.SH "SYSTEM MODE"
-.B qmail-authuser
-may also been used as a replacement for the
-.B checkpassword
-PAM, allowing to evaluate the 
-.I /etc/passwd
-and 
-.I shadow
-files for the auth methods USER, PLAIN & LOGIN 
-while only considerung the user part in 
-.IR authuser .
-In this case,
-.B qmail-authuser
-has to be \'sticky\' and running as 
-.IR root .
-.SH "VIRTUAL USER MODE"
-.B qmail-authuser
-includes the call of both
-.IR vpopmail 's
-.B vchkpw
-and
-.IR vmailmgr 's
-.B checkvpw 
-(which need to be in the path) 
-and transfers the received authentication information transparently to those.
-.SH "DOVECOT MODE"
-.B qmail-authuser 
-is also capabable to connect to a Unix socket created for authentication by
-.IR Dovecot .
-.SH "POP3 AND APOP"
-Calling
-.B qmail-authuser
-for POP3 authentication with the option
-.I qmail-pop3d 
-together with the format of the mailbox given as
-.IR maildirname ,
-which is typically
-.I Maildir 
-or
-.IR mbox .
-The required environment variables
-\fIUSER\fR, \fIHOME\fR, and \fISHELL\fR
-for the respective user are evaluated from
-.IR /etc/passwd .
-APOP authentication is possible for a given user, if
-.I authuser 
-and the
-.I password
-is included in
-.IR SQMAIL/users/authuser .
-Upon successful authentication 
-.B qmail-authuser
-changes to $\fIHOME\fR. 
-.SH "QUERY AND STORAGE MODES"
-The first character 
-.I X
-of the 
-.I password 
-token is used to indicate the password's query and storage method. 
-The following cases may be considered:
-
-.EX
-  (1a) authuser:clearpwd
-  (1b) authuser:%pwdhash
-  (2a) authuser:?
-  (2b) *:?
-  (3a) authuser:+
-  (3b) @domain:+
-  (3c) @:+
-  (3d) authuser:&
-  (3e) @domain:&
-  (3f) @:&
-  (4a) authuser:=
-  (4b) @domain:=
-  (4c) @:=
-.EE
-
-(1) Local query/storage:
-Here, together with the 
-.I authuser
-plaintext (1a) or hashed passwords (1b)
-may be provisioned in the
-.I SQMAIL/users/authuser
-control file.
-In case of
-.IR %pwdhash ,
-the password is stored as MD5, SHA1, or SHA256 hash prepended with the \'%\'.
-If the plaintext password is given as
-.I password
-this means that the following password is taken literally
-though allwowing a leading \'%\'.  
-
-(2) Unix system query/storage:
-In case the 
-.I password 
-token consists of
-.IR '?' ,
-the received authentication information is used to emulate a 
-standard Unix user login taking the 
-.I userid
-information as system user account. Therefore, no particular
-.I password 
-token is required here.
-The inclusion of any specific 
-.I authuser
-information can be avoided in case
-.I '*'
-is used as shortcut within
-.I SQMAIL/users/authuser
-followed by 
-.I '?'
-as 
-.I password 
-token. Now, the received
-.I userid 
-and password is taken from the Unix system for authentication (crypt).
-
-(3) Virtual domain query/storage:
-Alternatively, 
-.B qmail-authuser
-may call either 
-.B checkvpw
-once a 
-.I '+'
-or
-.B vchkpw
-in case 
-.I '&'
-is given as 
-.I password 
-token.
-
-(4) Dovecot as Identity Provider:
-.B Dovecot 
-can be used as authentication backend in case a
-.I '='
-is included as 
-.I password
-token. Assuming
-.B doveadm 
-is in the path, a particular
-.B auth-qmail
-listener (socket) is tested by
-.I doveadm 
-with the arguments
-.I \'auth test -a\' 
-provided the socket is available via 
-.IR \'-s\ authsocket\' .
-
-
-The definition of the auth socket 
-needs to be included in 
-.BR Dovecot 's
-control file in the following way:
-
-.EX
-service auth {
-  unix_listener /var/run/dovecot/auth-qmail {
-    mode = 0600
-    user = qmaild
-    group = nofiles
-  }
-}
-.EE
-
-Reversely, this socket has to be
-specified as calling argument for
-.B qmail-authuser 
-providing 
-.I -s /var/run/dovecot/auth-sqmail
-together with an additional executable (true).
-The name of the auth socket can
-be freely chosen.
-
-A particular authentication method 
-can be specified by means of
-.I -x service=authmethod
-in the call of 
-.BR qmail-authuser .
-Check the
-.b doveadmn
-documentation for particular authentication methods,
-typically available as \fIsmtp\fR and \fIpop3\fR.
-
-Note: All authentication storage and query mechanism
-can be used concurrently, depending on the settings
-of the
-.I authuser
-and 
-.I password
-token in
-.IR SQMAIL/users/authuser .
-.SH "SECURITY"
-.B qmail-authuser
-is invoked in the environment of 
-.BR qmail-smtpd ,
-.BR qmail-popup ,
-or
-.B bincimap-up
-which is typically run as user 
-.IR qmaild .
-The file
-.I SQMAIL/users/authuser
-shall be
-.I qmaild
-owned and belonging to the group
-.I sqmail 
-and SHOULD NOT be readble by the \fIworld\fR.
-
-Since the given
-.I authuser 
-token is visible in the email, it could be typically chosen as
-.I user@domain 
-making it usable for virtual domain managers and allowing
-a common
-.I password 
-for ESMTP/IMAP4/POP3 services.
-
-The included
-.I password
-token shall solely be used for ESMTP/IMAP4/POP3 authentication
-and should possess enough entropy. 
-
-A sticky and root-owned
-.B qmail-authuser
-is a potential security risk.
-.SH "PASSWORD HASHES"
-Instead of plaintext passwords, additionally
-MD5, SHA1, or SHA256  hashes of the passwords may be used. However, 
-in spite of rainbow tables this requires none-trivial passwords.  
-.SH "AUTH METHODS"
-In case hashed passwords or the UNIX passwords are used,
-only the auth methods USER, PLAIN, and LOGIN are working.
-Those methods are only secure on encrypted 
-connections or otherwise are an easy victim of an eavesdropper.
-Challenge/Response methods - like CRAM-MD5 and APOP -
-require having access to the plain-text passwords. For
-.B vchkpw
-C/R is possible querying the local \'vpopmail\' database.
-.SH "EXIT CODES"
-In case the provided
-.I authuser
-or 
-.I userid
-does not exist, or the digest and the response, 
-or the passwords
-differ,
-.B qmail-authuser
-exits 1.
-If
-.B qmail-authuser
-is misused, it may instead exit 2.
-In case 
-.I SQMAIL/users/authuser
-is not readeable, 
-.B qmail-authuser
-exits 110.
-If there is a temporary problem checking the password,
-.B qmail-authuser
-exits 111.
-.SH "ENVIRONMENT VARIABLES SET"
-Upon call,
-.B qmail-authuser
-clears the environment variable
-.I USER
-and sets to the 
-.I userid 
-irrespective whether authentication was successful or not.
-Since 
-.I USER
-may be used by other authentication PAMs called in the chain,
-additionally 
-.I AUTHUSER
-is set keeping the original
-.I userid
-information for logging purpose.
-.SH "CREDITS"
-The MD5 implementation originates from RSA though now supporting a
-64 bit OS as well. SHA1 has been created by Steve Reid, and
-SHA256 was done by Brad Conte, all released in the Public Domain.
-Drew Wells receives credits for putting me into the current direction.

-.B qmail-dkim
-is the implementation of
-.B libdkim
-for s/qmail providing API compatibility 
-and supporting RSA and Ed25519 DKIM signatures
-in single or hybrid mode.
-In hybrid mode, two 
-.I private keys
-and two
-.I selectors 
-need to be provided.
-.B qmail-dkim
-supports distinct operations:
-.TP 5
-.B qmail-dkim \fI-s in_message RSA_private_key out_message\fR
-DKIM signes 
-.I in_message
-with the given
-.I private_key 
-and returns
-.IR out_message .
-.TP 5 
-.B qmail-dkim \fI-s in_message RSA_private_key out_message Ed255_private_key\fR
-signs 
-.I in_message 
-with both a RSA 
-.I RSA_private_key 
-and a

-.TP 5
-.B qmail-dkim  \fI-v in_message\fR
-verifies the 
-.IR in_message .
-.SH "DKIM FORMATS"
-DKIM needs a common understanding of the attributes
-subject for signing and verification. 
-The following attributes can be set:
-.TP 5
--c
-is the 'canonicalization', thus how a validiation client
-should deal with signature verification of the 
-message headers and/or body. Here, the choices are given 
-via an appended character:
-.I r
-relax on header,
-.I s
-simple (strict) on message body,
-.I t
-relax/simple, or eventually
-.I u
-simple relaxed.
-Finally, the hash function to be used in the signature
-can be given as
-.TP 5
--z
-following either with
-.I 1
-using sha1, or 
-.I 2
-using sha256, or finally as default
-.I 3
-providing both signature values in the mail header.
-.I 4
-telling 
-.B qmail-dkim
-to use the Ed25519 signature scheme.
-.I 5
-allows
-.B qmail-dkim 
-to attach both a 
-.I RSA-SHA256
-as well as a
-.I Ed25519
-signature to the message, which considered to be a
-.I hybrid
-mode.
-
-.SH "DKIM SIGNING"
-.B qmail-dkim
-will include (several) message headers detailing the
-.B DKIM signature
-with at least the following fields:
-.TP 3
-a
-=<signature type>
-.TP 3
-c
-=<used canoncicalization>
-.TP 3

-=<included header1:header2:...>
-.TP 3
-bh
-=<hash of the canonicalized body until its upper limit length; if given>
-.TP 3
-b
-=<base64 encoded signature>
-.P
-Additional settings can be achieved using the following options:
-.TP 5
-.I -d domain
-is the signer's domain name and together with the prepended
-.TP 5
-.I -y selector
-it is used for the DNS TXT lookup of the public key; supporting
-mainly key roll-over. The first selector is used for RSA signatures.
-.TP 5
-.I -Y selector2
-Same as \fI-y\fR but now for Ed25519 signatures.
-.TP 5
-.I -I identifier
-giving an additional hint about the agent or identifier
-responsible for the signing like 'postmaster@domain'; defaults to 
-.IR domain .
-.TP 5
-.I -t expire_time
-given in seconds, tells how log the signature is valid. 
-It defaults to 
-.I 604800
-secconds (seven days).
-.P
-Further, some more option fields can be displayed in the header:
-.TP 5
-.I -l
-include a body length tag.
-.TP 5
-.I -q
-include the query method tag.
-
-.SH "DKIM VERIFICATION"
-.B qmail-dkim
-as invoked by
-.B qmail-dkverify
-extracting the received DKIM header fields,
-and following the signature verification procedure
-as given here, while fetching the signer's
-.I public key
-using a DNS TXT lookup.
-Now, the respective header lines, and/or
-the message body will be hashed and compared
-against the values taken from the signatures.
-
-The results will be indicated by either return code
-.I 0 
-in case of success, 
-.I 1
-in case of mismatch, or
-.I -1
-if other failures were encountered.

-will now pick up those and use the provided key for signing.
-
-However, in general this reqires to deploy DKIM records
-for those domains sharing the same public key but require
-different domain names as distinguished DNS TXT records.
-
-Rather, you may want to publish just one
-DKIM DNS TXT record which is commonly shared for all 
-concerning domains. Since the 
-.I sending\ domain
-is used as default for the
-.IR SDID ,
-you need now to provide the same
-.I SDID
-explicitely for each domain of concern in
-.IR control/dkimdomains .
-
-The '<selector>' - and not the SDID - 
-together with the literal
-.I ._domainkey.
-and the domain name defines the binding of the

-.IR <selector>._domainkey.<domain> .
-
-.SH "GNERATING CRYPTO MATERIAL"
-Public/private keys can be generated by

-should return ETXTBSY to indicate temporary errors
-and ESRCH to indicate nonexistent users.
-.SH "RULES"
-.B qmail-getpw
-considers an account in
-.B /etc/passwd
-to be a user if
-(1) the account has a nonzero uid,
-(2) the account's home directory exists (and is visible to
-.BR qmail-getpw ),
-and
-(3) the account owns its home directory.
-.B qmail-getpw
-ignores account names containing uppercase letters.
-.B qmail-getpw
-also assumes that all account names are shorter than 32 characters.
-
-.B qmail-getpw
-gives each user
-control over the basic
-.I user
-address and
-all addresses of the form
-.IR user\fBBREAK\fIanything .
-When
-.I local
-is
-.IR user ,
-.I dash
-and
-.I ext
-are both empty.
-When
-.I local
-is
-.IR user\fBBREAK\fIanything ,
-.I dash
-is a hyphen and
-.I ext
-is
-.IR anything .
-.I user
-may appear in any combination of uppercase and lowercase letters
-at the front of
-.IR local .
-
-A catch-all user,
-.BR alias ,
-controls all other addresses.
-In this case
-.I ext
-is
-.I local
-and
-.I dash
-is a hyphen.
-
-You can override all of
-.BR qmail-getpw 's
-decisions with the
-.B qmail-users
-mechanism, which is reliable, highly configurable, and much faster than
-.BR qmail-getpw .

-.TH s/qmail: qmail-header 5
-.SH NAME
-qmail-header \- format of a mail message
-.SH OVERVIEW
-At the top of every mail message is a
-highly structured
-.BR header .
-Many programs expect the header to carry certain information,
-as described below.
-The main function of
-.B qmail-inject
-is to make sure that each outgoing message has an appropriate header.
-
-For more detailed information, see
-.BR http://pobox.com/~djb/proto/immhf.html .
-.SH "MESSAGE STRUCTURE"
-A message contains a series of
-.I header fields\fR,
-a blank line,
-and a
-.IR body :
-
-.EX
-     Received: (qmail-queue invoked by uid 666);
-.br
-	     30 Jul 1996 11:54:54 -0000
-.br
-     From: djb@silverton.berkeley.edu (D. J. Bernstein)
-.br
-     To: fred@silverton.berkeley.edu
-.br
-     Date: 30 Jul 1996 11:54:54 -0000
-.br
-     Subject: Go, Bears!
-.br
-
-.br
-     I've got money on this one.  How about you?
-.br
-
-.br
-     ---Dan   (this is the third line of the body)
-.EE
-
-Each header field has a
-.IR name ,
-a colon,
-some
-.IR contents ,
-and a newline:
-
-.EX
-     Subject: Go, Bears!
-.EE
-
-The field contents may be folded across several lines.
-Each line past the first must begin with a space or tab:
-
-.EX
-     Received: (qmail-queue invoked by uid 666);
-.br
-	     30 Jul 1996 11:54:54 -0000
-.EE
-
-The field name must not contain spaces, tabs, or colons.
-Also, an empty field name is illegal.
-.B qmail-inject
-does not allow field names with unprintable characters.
-
-Case is irrelevant in field names:
-.B subject
-and
-.B SUBJECT
-and
-.B SuBjEcT
-have the same meaning.
-.SH "ADDRESS LISTS"
-Certain fields, such as
-.BR To ,
-contain
-.I address lists\fR.
-
-An address list contains some number of
-.I addresses
-or
-.I address groups\fR,
-separated by commas:
-
-.EX
-     a@b, c@d (Somebody), A Person <e@f>,
-.br
-        random group: g@h, i@j;, k@l
-.EE
-
-An
-.I address group
-has some text, a colon, a list of addresses,
-and a semicolon:
-
-.EX
-        random group: g@h, i@j;
-.EE
-
-An address can appear in several forms.
-The most common form is
-.IR box@host .
-
-Every address must include a host name.
-If
-.B qmail-inject
-sees a lone box name
-it adds the
-.I default host name\fR.
-
-All host names should be fully qualified.
-.B qmail-inject
-appends the
-.I default domain name
-to any name without dots:
-
-.EX
-     djb@silverton  ->  djb@silverton.berkeley.edu
-.EE
-
-It appends the
-.I plus domain name
-to any name
-that ends with a plus sign:
-
-.EX
-     eric@mammoth.cs+  ->  eric@mammoth.cs.berkeley.edu
-.EE
-
-A host name may be a dotted-decimal address:
-
-.EX
-     djb@[128.32.183.163]
-.EE
-
-RFC 822 allows mailbox names inside angle brackets
-to include
-.I source routes\fR,
-but
-.B qmail-inject
-strips all source routes out of addresses.
-.SH "SENDER ADDRESSES"
-.B qmail-inject
-looks for sender address lists in the following fields:
-.BR Sender ,
-.BR From ,
-.BR Reply-To ,
-.BR Return-Path ,
-.BR Return-Receipt-To ,
-.BR Errors-To ,
-.BR Resent-Sender ,
-.BR Resent-From ,
-.BR Resent-Reply-To .
-
-If there is no
-.B From
-field,
-.B qmail-inject
-adds a new
-.B From
-field with the name of the user invoking
-.B qmail-inject.
-
-RFC 822 requires that certain sender fields contain
-only a single address, but
-.B qmail-inject
-does not enforce this restriction.
-.SH "RECIPIENT ADDRESSES"
-.B qmail-inject
-looks for recipient address lists in the following fields:
-.BR To ,
-.BR Cc ,
-.BR Bcc ,
-.BR Apparently-To ,
-.BR Resent-To ,
-.BR Resent-Cc ,
-.BR Resent-Bcc .
-
-Every message must contain at least one
-.B To
-or
-.B Cc
-or
-.BR Bcc .
-.B qmail-inject
-deletes any
-.B Bcc
-field.
-If there is no
-.B To
-or
-.B Cc
-field,
-.B qmail-inject
-adds a line
-
-.EX
-     Cc: recipient list not shown: ;
-.EE
-
-This complies with RFC 822;
-it also works around some strange
-.B sendmail
-behavior, in case the message is passed through
-.B sendmail
-on another machine.
-.SH STAMPS
-Every message must contain a
-.B Date
-field, with the date in a strict format defined by RFC 822.
-If necessary
-.B qmail-inject
-creates a new
-.B Date
-field with the current date (in GMT).
-
-Every message should contain a
-.B Message-Id
-field.
-The field contents are a unique worldwide identifier for this message.
-If necessary
-.B qmail-inject
-creates a new
-.B Message-Id
-field.
-
-Another important field is
-.BR Received .
-Every time the message is sent from one system to another,
-a new
-.B Received
-field is added to the top of the message.
-.B qmail-inject
-does not create any
-.B Received
-fields.
-.SH "RESENT MESSAGES"
-A message is
-.I resent
-if it contains any of the following fields:
-.BR Resent-Sender ,
-.BR Resent-From ,
-.BR Resent-Reply-To ,
-.BR Resent-To ,
-.BR Resent-Cc ,
-.BR Resent-Bcc ,
-.BR Resent-Date ,
-.BR Resent-Message-ID .
-
-If a message is resent,
-.B qmail-inject
-changes its behavior as follows.
-
-It deletes any
-.B Resent-Bcc
-field (as well as any
-.B Bcc
-field);
-if there are no
-.B Resent-To
-or
-.B Resent-Cc
-fields,
-.B qmail-inject
-adds an appropriate
-.B Resent-Cc
-line.
-It does
-.I not
-add a
-.B Cc
-line,
-even if neither
-.B To
-nor
-.B Cc
-is present.
-
-If there is no
-.B Resent-From
-field,
-.B qmail-inject
-adds a new
-.B Resent-From
-field.
-It does
-.I not
-add a new
-.B From
-field.
-
-.B qmail-inject
-adds
-.B Resent-Date
-if one is not already present;
-same for
-.BR Resent-Message-Id .
-It does
-.I not
-add new
-.B Date
-or
-.B Message-Id
-fields.
-.SH "OTHER FEATURES"
-Addresses are separated by commas, not spaces.
-When
-.B qmail-inject
-sees an illegal space,
-it inserts a comma:
-
-.EX
-     djb fred  ->  djb, fred
-.EE
-
-.B qmail-inject
-removes all
-.B Return-Path
-header fields.
-
-.B qmail-inject
-also removes any
-.B Content-Length
-fields.

-.SH SYNOPSIS
-.B qmail-inject
-[
-.B \-nNaAhH
-] [
-.B \-f\fIsender
-] [
-.I recip ...
-]
-.SH DESCRIPTION
-.B qmail-inject
-reads a mail message from its standard input,
-adds appropriate information to the message header,
-and invokes
-.B qmail-queue
-to send the message
-to one or more recipients.
-
-See
-.B qmail-header(5)
-for information on how
-.B qmail-inject
-rewrites header fields.
-
-.B qmail-inject
-normally exits 0.
-It exits 100 if it was invoked improperly
-or if there is a severe syntax error in the message.
-It exits 111 for temporary errors.
-.SH "ENVIRONMENT VARIABLES"
-For the convenience of users who do not run
-.B qmail-inject
-directly,
-.B qmail-inject
-takes many options through environment variables.
-
-The user name in the
-.B From
-header field is set by
-.BR QMAILUSER ,
-.BR MAILUSER ,
-.BR USER ,
-or
-.BR LOGNAME ,
-whichever comes first.
-
-The host name is normally set by the
-.I defaulthost
-control
-but can be overridden with
-.B QMAILHOST
-or
-.BR MAILHOST .
-
-The personal name is
-.BR QMAILNAME ,
-.BR MAILNAME ,
-or
-.BR NAME .
-
-The default envelope sender address is the same as the
-default
-.B From
-address,
-but it can be overridden with
-.B QMAILSUSER
-and
-.BR QMAILSHOST .
-It may also be modified by the
-.B r
-and
-.B m
-letters described below.
-Bounces will be sent to this address.
-
-If
-.B QMAILMFTFILE
-is set,
-.B qmail-inject
-reads a list of mailing list addresses,
-one per line,
-from that file.
-If To+Cc includes one of those addresses (without regard to case),
-.B qmail-inject
-adds a Mail-Followup-To field
-with all the To+Cc addresses.
-.B qmail-inject
-does not add Mail-Followup-To
-to a message that already has one.
-
-The
-.B QMAILINJECT
-environment variable
-can contain any of the following letters:
-.TP
-.B c
-Use address-comment style for the
-.B From
-field.
-Normally
-.B qmail-inject
-uses name-address style.
-.TP
-.B s
-Do not look at any incoming
-.B Return-Path
-field.
-Normally, if
-.B Return-Path
-is supplied, it sets the envelope sender address,
-overriding all environment variables.
-.B Return-Path
-is deleted in any case.
-.TP
-.B f
-Delete any incoming
-.B From
-field.
-Normally, if
-.B From
-is supplied, it overrides the usual
-.B From
-field created by
-.BR qmail-inject .
-.TP
-.B i
-Delete any incoming
-.B Message-ID
-field.
-Normally, if
-.B Message-ID
-is supplied, it overrides the usual
-.B Message-ID
-field created by
-.BR qmail-inject .
-.TP
-.B r
-Use a per-recipient VERP.
-.B qmail-inject
-will append each recipient address to the envelope sender
-of the copy going to that recipient.
-.TP
-.B m
-Use a per-message VERP.
-.B qmail-inject
-will append the current date and process ID to the envelope sender.
-.SH OPTIONS
-.TP
-.B \-a
-Send the message to all addresses given as
-.I recip
-arguments;
-do not use header recipient addresses.
-.TP
-.B \-h
-Send the message to all header recipient addresses.
-For non-forwarded messages, this means
-the addresses listed under
-.BR To ,
-.BR Cc ,
-.BR Bcc ,
-.BR Apparently-To .
-For forwarded messages, this means
-the addresses listed under
-.BR Resent-To ,
-.BR Resent-Cc ,
-.BR Resent-Bcc .
-Do not use any
-.I recip
-arguments.
-.TP
-.B \-A

-as the envelope sender address.
-This overrides
-.B Return-Path
-and all environment variables.
-.TP
-.B \-N
-(Default.)
-Feed the resulting message to
-.BR qmail-queue .
-.TP
-.B \-n
-Print the message rather than feeding it to

-.SH "CONTROL FILES"
-.TP 5
-.I defaultdomain
-Default domain name.
-Default:
-.IR me ,
-if that is supplied;
-otherwise the literal name
-.BR defaultdomain ,
-which is probably not what you want.
-.B qmail-inject
-adds this name to any host name without dots,
-including
-.I defaulthost
-if
-.I defaulthost
-does not have dots.
-(Exception: see

-.I idhost
-need not be the current host's name.
-For example, you may prefer to use fake
-host names in Message-IDs.
-However,
-.I idhost
-must be a fully-qualified name within your domain,
-and each host in your domain should use a different
-.IR idhost .
-
-The
-.B QMAILIDHOST
-environment variable overrides
-.IR idhost .
-.TP 5
-.I plusdomain
-Plus domain name.
-Default:
-.IR me ,
-if that is supplied;
-otherwise the literal name
-.BR plusdomain ,
-which is probably not what you want.
-.B qmail-inject
-adds this name to any host name that ends with a plus sign,
-including
-.I defaulthost
-if
-.I defaulthost
-ends with a plus sign.
-If a host name does not have dots but ends with a plus sign,
-.B qmail-inject
-uses
-.IR plusdomain ,
-not
-.IR defaultdomain .
-
-The
-.B QMAILPLUSDOMAIN
-environment variable overrides

-asynchronously,
-so the results may not be in the same order as the commands.
-
-For each recipient address,

-finds out which local user controls that address.
-It first checks the

-.B qmail-mfrules
-reads the addresses provided in

-converts them into lowercase, and writes them into
-.B SQMAIL/control/mailfromrules.cdb
-in a binary format suited

-If there is a problem with

-
-.B qmail-mfrules
-ensures that

-However,
-.B qmail-mfrules
-makes no attempt to protect against two simultaneous updates of
-.BR control/mailfromrules.cdb .
-
-The binary
-.B control/mailfromrules.cdb
-format is portable across machines.
-
-.SH "RULE FORMAT"
-A rule is one line. A file containing rules may also contain comments: lines
-beginning with # are ignored. All addresses are evaluated case-insensitive.
-
-Each rule contains an address, an ampersend sign '&', and a list of strings separated by 
-commas to be used for 'Mail From: Address Verification' (MAV). When
-.BR qmail-smtpd (8)
-receives a connection from that address, it checks whether the received 
-envelope sender address correspondes with a MAV string (from the right 
-to the left). 
-The MAV string for an address may be NULL in order to allow any envelope
-sender address. NULLSENDER envelope addresses are not subject of the MAV.
-
-.SH "RULE BASE"
-.BR qmail-smtpd (8)
-looks for rules with various addresses in the following order:
-.IP 1
-$TCPREMOTEINFO, if $TCPREMOTEINFO is set (e.g. by SMTP Authentication);
-.IP 2.
-$TCPREMOTEINFO@$TCPREMOTEIP, if $TCPREMOTEINFO is set;
-.IP 3.
-$TCPREMOTEINFO@=$TCPREMOTEHOST, if $TCPREMOTEINFO is set and $TCPREMOTEHOST is
-set;
-.IP 4.
-the dotted decimal $TCPREMOTEIP address;
-.IP 5.
-the compactified $TCPREMOTEIP6 address;
-.IP 6.
-=$TCPREMOTEHOST, if $TCPREMOTEHOST is set;
-.IP 7.
-shorter and shorter prefixes of $TCPREMOTEIP ending with a dot;
-.IP 8.
-shorter and shorter values of $TCPREMOTEIP6 ending with a colon;
-.IP 9.
-shorter and shorter suffixes of $TCPREMOTEHOST starting with a dot, preceded
-by =, if $TCPREMOTEHOST is set; and finally
-.IP 10.
-=, if $TCPREMOTEHOST is set.
-.P
-.B qmail-smtpd
-employes the first matching rule for the MAV check. You should use the
-.B -p
-option to
-.BR sslserver
-if you rely on $TCPREMOTEHOST here.
-
-For example, here are some rules:
-
-.EX
-  jsmith@virtualdomain.com&john.smith@virtualdomain.com

-  18.23&@example.com

-.SH NAME
-qmail-postgrey \- send SMTP connection data to greylisting server
-.SH SYNOPSIS
-.B qmail-postgrey ip%netid;port Mail From: Rcpt To: TCPREMOTEIP TCPREMOTEHOST
-.SH DESCRIPTION
-.B qmail-postgrey
-is usually invoked by
-.B qmail-smtpd
-automatically provissioning the SMTP connection information
-.IR Mail\ From: ,
-.IR Rcpt\ To: ,
-.IR TCPREMOTEIP 
-and
-.I TCPREMOTEHOST
-to a greylising server given by
-.IR IPv4|IPv6%netid;port .
-.I port
-defaults to 
-.I 60000
-and thus can be omitted. 
-IPv6 LLU addresses can be specified
-adding the 
-.I netid 
-name following the percentage sign.
-.SH "GREYLISTING SERVER"
-Since there is neither a formal API defined for the
-greylisting lookup nor for the behavior and return
-codes of the greylisting server, 
-.B qmail-postgrey
-only works well with
-.I David\ Schweikert's
-.B postgrey
-implementation.
-
-Here, the server's response upon recognizing the triple
-.RI CLIENT_IP ,
-.I (SMTP\ envelope)\ SENDER
-and 
-.I (SMTP\ envelope)\ RECIPIENT
-is either
-.IR action=DUNNO ,
-.I action=PREPEND
-or
-.I action=DEFER_IF_PERMIT
-and in case of the last,
-.B qmail-postgrey
-returns with
-.I 10
-telling 
-.B qmail-smtpd
-to respond to the client with a SMTP
-.I 450\ greylisted
-reply code. Otherwise
-.B qmail-postgrey
-returns
-.IR 0 .
-.SH "INVOCATION"
-Unlike for testing reasons,
-.B qmail-postgrey
-is called directly from 
-.B qmail-smtpd
-in case the environment variable
-.I POSTGREY
-is defined and provissioned with the greylisting 
-server's IP address (and perhaps netid and port)
-listening there.
-
-The environment variable
-.I POSTGREY
-is typically defined within
-.B sslserver\'s
-.IR cdb .
-Additionally, 
-.I REPLY_GREYLISTED
-can be used as environment variable 
-to provide some more descriptive
-information to the sending MTA which will eventually
-be visible in a bounce message. 
-.SH "CREDITS"
-.B qmail-postgrey 
-and its integration into 
-.B qmail-smtpd
-is based on 
-.I Jan\ Mojzis
-implementation and used by permission.

-.SH DESCRIPTION
-.B qmail-pw2u
-reads a V7-format passwd file from standard input
-and prints a
-.BR qmail-users -format
-assignment file.
-
-A V7-format passwd file is a series of lines.
-Each line has the format
-
-.EX
-   user:password:uid:gid:gecos:home:shell
-.EE
-
-where
-.I user
-is an account name,
-.I uid
-and
-.I gid
-are the user id and group id of that account,
-and
-.I home
-is the account's home directory.
-.IR password ,
-.IR gecos ,
-and
-.I shell
-are ignored by
-.BR qmail-pw2u .
-
-If you put the output of
-.B qmail-pw2u
-into
-.BR SQMAIL/users/assign ,
-and then run
-.BR qmail-newu ,
-.B qmail-lspawn
-will obey the assignments printed by
-.BR qmail-pw2u .
-.B WARNING:
-After changing any users, uids, gids, or home directories
-in your passwd file,
-you must run
-.B qmail-pw2u
-and
-.B qmail-newu
-again if you want
-.B qmail-lspawn
-to see the changes.
-.SH RULES
-By default,
-.B qmail-pw2u
-follows the same rules as
-.BR qmail-getpw .
-It skips
-.I user
-if (1)
-.I uid
-is zero,
-(2)
-.I home
-does not exist,
-(3)
-.I user
-does not own
-.IR home ,
-or
-(4)
-.I user
-contains uppercase letters.
-It then gives each remaining
-.I user
-control over the basic
-.I user
-address and
-all addresses of the form
-.IR user\fBBREAK\fIanything .
-A catch-all user,
-.BR alias ,
-controls all other addresses.
-
-You may change these rules by setting up files in
-.BR SQMAIL/users :
-.TP
-.B include
-Allowed users, one per line.
-If
-.B include
-exists, and
-.I user
-is not listed in
-.BR include ,
-.I user
-is ignored.
-.TP
-.B exclude
-Ignored users, one per line.
-If
-.B exclude
-exists, and
-.I user
-is listed in
-.BR exclude ,
-.I user
-is ignored.

-.I user
-and
-.I user\fBBREAK\fIext
-will not be delivered to

-.SH SYNOPSIS
-.B qmail-queue
-.SH DESCRIPTION
-.B qmail-queue
-reads a mail message from descriptor 0.
-It then reads envelope information from descriptor 1.
-It places the message into the outgoing queue
-for future delivery by

-
-The envelope information is
-an envelope sender address
-followed by a list of envelope recipient addresses.
-The sender address is preceded by the letter F

-and terminated by a 0 byte.
-The list of recipient addresses is terminated by an extra 0 byte.
-If

-sees end-of-file before the extra 0 byte,
-it aborts without placing the message into the queue.
-
-Every envelope recipient address
-should contain a username,

-
-.B qmail-queue
-always adds a
-.B Received
-line to the top of the message.
-Other than this,
-.B qmail-queue
-does not inspect the message
-and does not enforce any restrictions on its contents.
-However, the recipients probably expect to see a proper header,

-
-Programs included with qmail which invoke
-.B qmail-queue
-will invoke the contents of
-.B QMAILQUEUE
-instead, if that environment variable is set.
-.SH "FILESYSTEM RESTRICTIONS"
-.B qmail-queue
-imposes two constraints on the queue structure:
-each
-.B mess
-subdirectory must be in the same filesystem as the
-.B pid
-directory; and each
-.B todo
-subdirectory must be in the same filesystem as the

-It exits between 1 and 99 if
-it has failed to queue the message.

-Optional additional arguments can be included here, ie. QHPSIARG1="--verbose". 
-Useful to suppress output in case an email is
-clean and to enable mailbox support for the virus scanner.

-.B QHPSIRC
-To specify the return code of the virus scanner in case of an infection; default is 1.
-.TP
-.B QHPSIMINSIZE
-The minimal size of the message to invoke the virus scanner; default is 0.

-.SH NAME
-qmail-remote \- send mail via SMTP(S) or QMTP(S)
-.SH SYNOPSIS
-.B qmail-remote
-.I host
-.I sender
-.I recip
-[
-.I recip ...
-]
-.SH DESCRIPTION
-.B qmail-remote
-reads a mail message from its input
-and sends the message
-to one or more recipients
-at a remote host.
-
-The remote host is
-.BR qmail-remote 's
-first argument,
-.IR host .
-.B qmail-remote
-sends the message to
-.IR host ,
-or to a mail exchanger for
-.I host
-listed in the Domain Name System,
-via the Simple Mail Transfer Protocol (SMTP/ESMTP) 
-perhaps encrypted via STARTTLS/TLS
-or the Quick Mail Transfer Protocol (QMTP/QMTPS).
-Prior of setting up a TLS connection, 
-.B qmail-remote 
-will lookup automatically the corresponding TLSA
-record in the DNS and uses this for X.509 certificate
-validation.
-.I host
-can be either a fully-qualified domain name:
-
-.EX
-     silverton.berkeley.edu
-.EE
-
-or an IPv4 or IPv6  address enclosed in brackets:
-
-.EX
-     [128.32.183.163]
-     [2001::163]
-.EE
- 
-In case the primary mail exchanger for that Domain
-will issue a 5xy reply message during the connection,
-.B qmail-remote
-will contact all responsible mail exchangers in turn
-in order to deliver the message anyway.
-
-The envelope recipient addresses are listed as
-.I recip
-arguments to
-.BR qmail-remote .
-The envelope sender address is listed as
-.I sender\fP.
-
-In case the remote host issues the EHLO SIZE extension,
-.I qmail-remote
-will handover the size of the message (in byte) 
-prior of transmission and respects the remote host's reply code.
-
-Note that
-.B qmail-remote
-does not take options
-and does not follow the
-.B getopt
-standard.
-.SH "TRANSPARENCY"
-End-of-file in SMTP is encoded as dot CR LF.
-A dot at the beginning of a line is encoded as dot dot.
-It is impossible in SMTP to send a message that does not end with a newline.
-.B qmail-remote
-respects SMTPUTF8 and EAI addresses 
-and converts the UNIX newline convention into the 
-SMTP newline convention by inserting CR before each LF.
-
-.SH "RESULTS"
-.B qmail-remote
-prints some number of 
-.I recipient reports\fP,
-followed by a
-.I message report\fR.
-Each report is terminated by a 0 byte.
-Each report begins with a single letter:
-.TP 5
-r
-Recipient report: acceptance.
-.TP 5
-h
-Recipient report: permanent rejection.
-.TP 5
-s
-Recipient report: temporary rejection.
-.TP 5
-K
-Message report: success.
-.I host
-has taken responsibility for delivering the message to each
-acceptable recipient.
-.TP 5
-Z
-Message report: greylisted or temporary failure.
-.TP 5
-D
-Message report: permanent failure.
-.PP
-After this letter comes a human-readable description of
-what happened.
-
-.B qmail-remote
-may use SMTP Authenticaton to connect to remote hosts.
-The following reports are provided:
-.TP 5
-K
-no supported AUTH s/qmail: method found, continuing without authentication.
-.TP 5
-Z
-Connected to 
-.I host
-but authentication was rejected (AUTH s/qmail: PLAIN).
-.TP 5
-Z
-Connected to 
-.I host 
-but unable to base64encode (plain).
-.TP 5
-Z
-Connected to 
-.I host
-but authentication was rejected (plain). 
-.TP 5
-Z
-Connected to
-.I host
-but authentication was rejected (AUTH s/qmail: LOGIN).
-.TP 5
-Z
-Connected to 
-.I host
-but unable to base64encode user.
-.TP 5
-Z
-Connected to 
-.I host 
-but authentication was rejected (username).
-.TP 5
-Z
-Connected to 
-.I host 
-but unable to base64encode pass.
-.TP 5
-Z
-Connected to
-.I host
-but authentication was rejected (AUTH s/qmail: CRAM-MD5).
-.TP 5
-Z
-Connected to
-.I host
-but unable to base64decode challenge.
-.TP 5
-Z
-Connected to
-.I host
-but unable to base64encode username+digest.
-.TP 5
-Z
-Connected to
-.I host
-but authentication was rejected (username+digest).
-.PP
-The recipient reports will always be printed in the same order as
-.BR qmail-remote 's
-.I recip
-arguments.
-Note that in failure cases there may be fewer
-recipient reports
-than
-.I recip
-arguments.
-.PP
-In case a CNAME can not be resovled 
-.B qmail-remote
-issues the following message:
-.TP 5
-Z
-CNAME lookup failed temporarily for:
-.IR host . 
-.PP
-If a SMTP connection is bound to a none-existing IP address
-.B qmail-remote
-will complain with the message:
-.TP 5
-Z
-System resources temporarily unavailable.
-.TP 5
-Z
-System can't bind to local ip address:
-.IR ip .
-.PP
-In case a QMTP connection can not be established 
-.B qmail-remote
-will issue the error message:
-.TP 5
-Z 
-recipient
-.I host
-did not talk proper QMTP.
-.PP
-On demand
-.B qmail-remote
-supports TLS/STARTTLS and will log the following notifications:
-.TP 5
-K
-TLS transmitted message accepted
-.TP 5
-K
-TLS (verfied CA) transmitted message accepted
-.TP 5
-K
-TLS (verified CA+DN*) transmitted message accepted
-.TP 5
-K
-TLS (verified CA+DN) transmitted message accepted
-.TP 5
-K
-TLS (CERT pinning) transmitted message accepted
-.TP 5
-K
-TLS (TLSA validated) transmitted message accepted
-.PP
-.B qmail-remote 
-needs to read some X.509 certificates and key files 
-prior of setting up a TLS connection. Failures are indicated as:
-.TP 5
-Z
-Can't load X.509 certificate:
-.IR certfile .
-.TP 5
-Z
-Can't load X.509 private key:
-.IR keyfile .
-.TP 5
-Z
-Keyfile does not match X.509 certificate:
-.IR password .
-.TP 5
-Z
-I wasn't able to process the TLS ciphers:
-.IR ciphers .
-.TP 5
-Z
-I wasn't able to setup CAFILE:
-.I cafile
-or CADIR:
-.I cadir
-for TLS.
-.PP
-Connection problems for TLS are not uncommon.
-Here, 
-.I host
-is the domain or host to connect with and
-.I remotehost
-is the corresponding MX.
-.B
-qmail-remote
-provides the following diagnostic messages:
-.TP 5
-Z
-I wasn't able to create TLS context for:
-.I host 
-at
-.IR remotehost .
-.TP 5
-Z
-I wasn't able to establish a TLS connection with:
-.I remotehost 
-for 
-.IR host .
-.TP 5

-TLS connection/protocol error with host:
-.I remotehost 
-for 
-.IR host .
-.TP 5
-Z
-I wasn't able to negotiate a StartTLS connection with:
-.I remotehost
-for
-.IR host .
-.PP
-For each MX to reach via TLS,
-.B qmail-remote
-performs an automatic TLSA lookup comparing the received
-X.509 fingerprints with the issued cert during the TLS handshake.
-X.509 certificate checks can also been performed. Failures here 
-are given as:
-.TP 5
-Z
-Unable to obtain X.500 certificate from:
-.I remotehost
-for
-.IR host .
-.TP 5

-.PP
-.SH "CONTROL FILES"
-.TP 5
-.I authsenders
-Authenticated sender.
-For each
-.I sender 
-included in 
-.IR authsenders :
-.I sender\fB:\fIrelay\fB;\fI[s]port\fB|\fIuser\fB|\fIpassword 
-.B qmail-remote
-will try SMTP Authentication 
-of type CRAM-MD5, LOGIN, or PLAIN 
-with the provided user name
-.I user 
-and password
-.I password 
-(the authentication information) 
-and eventually relay the 
-mail through
-.I relay
-on port
-.IR port .
-If 
-.I port
-is given als or prepended with
-.I s
-like
-.I s587
-\'implicit TLS\' is used omitting StartTLS upon connection.
-The use of 
-.I relay
-and 
-.I port 
-follows the same rules as for
-.IR smtproutes 
-Note: In case
-.I sender
-is empty, 
-.B qmail-remote
-will try to deliver each outgoing mail 
-SMTP authenticated. If the authentication
-information is missing, the mail is 
-delivered none-authenticated.
-.I authsenders
-can be constructed as follows:
-
-.EX
-   @example.com:relay.example.com|user|passwd
-   info@example.com:relay.example.com;26|infouser|infopasswd
-   :mailrelay.example.com|e=mc2|testpass
-.EE
-.TP 5
-.I domaincerts
-In case
-.B qmail-remote
-needs to present a client certificate to the server 
-(for authentication purposes) the PEM encoded 
-X.509 certificate can be provided per sending domain:
-.IR domain\fB:\fIcertificate\fB|\fIkeyfile\fB|\fIpassword .
-If 
-.I domain
-equals '*' this
-.I certificate
-is used as default.
-The file 
-.I certificate 
-may include the private key, thus 
-.I keyfile
-can be omitted. Additionally, the private key can be protected with a
-.IR password .
-
-.TP 5
-.I domainips
-IP addresses to be used for outgoing connections.
-Each line has the form
-.IR domain\fB:\fIlocalip(%ifname)\fB|\fIhelohost ,
-without any extra spaces.
-If
-.I domain
-matches the domain part in
-.IR sender ,
-.B qmail-remote
-will bind to
-.IR localip
-when connecting to
-.IR host .
-LLU IPv6 addresses need to be appended with the binding 
-.IR ifname
-following
-.IR localip 
-with a '%'.
-If it matches, it will set the provided HELO string as greeting; 
-otherwise, it will use the default.
-.I domain 
-can be the wildcard
-.I *
-in which case 
-.B qmail-remote
-binds to the provided address for any sender domain name.
-.TP 5
-.I helohost
-Current host name,
-for use solely in saying ehlo/hello to the remote SMTP server.
-Default:
-.IR me ,
-if that is supplied;
-otherwise
-.B qmail-remote
-refuses to run.
-.TP 5
-.I qmtproutes
-Additional QMTP routes which have precedence over
-.IR smtproutes .
-QMTP routes should obey the form
-.IR domain\fB:\fIrelay\fB;\fIport ,
-without any extra spaces.
-.I qmtproutes
-follows the same syntax as
-.IR smtproutes .
-By default, 
-.B qmail-remote
-connects to QMTP service port 209. However
-you can chose a dedicated high-port for QMTP communication
-as defined in
-.IR qmtproutes .
-In case the QMTP port is chosen to be
-.I 6209
-the TLS secured QMTPS protocol will be used, 
-irrespectively of the settings in 
-.IR tlsdestinations .
-.TP 5
-.I smtproutes
-Artificial SMTP routes.
-Each route has the well-known form
-.I domain\fB:\fIrelay 
-or the enhanced syntax
-.I domain\fB:\fIrelay;\fI[s]port\fB|\fIuser\fB|\fIpassword|localip
-without any extra spaces.
-If
-.I domain
-matches
-.IR host ,
-.B qmail-remote
-will connect to
-.IR relay ,
-as if
-.I host
-had
-.I relay
-as its only MX.
-(It will also avoid doing any CNAME lookups on
-.IR recip .)
-.I host
-may include a semi-colon and a port number to use instead of the
-normal SMTP port, 25. 
-If 
-.I port
-is given as or prepended with
-.I s
-\'implicit TLS\' is assumed.
-In case, a userid and password is
-present,
-.B qmail-remote
-will try a SMTP authenticated session:
-
-.EX
-   inside.af.mil:firewall.af.mil;26
-   :submission.myrelay.com;s587|myuserid|mypasswd
-.EE
-
-However,
-.I authsenders
-routes have precedence.
-
-.I relay
-may be empty;
-this tells
-.B qmail-remote
-to look up MX records as usual.
-.I smtproutes
-may include wildcards:
-
-.EX
-   .af.mil:
-   :heaven.af.mil
-.EE
-
-Here
-any address ending with
-.B .af.mil
-(but not
-.B af.mil
-itself)
-is routed by its MX records;
-any other address is artificially routed to
-.BR heaven.af.mil .
-
-The outgoing IP address used by
-.B qmail-remote
-can be specified:
-
-.EX
-   :bouncehost.org||10.1.1.0
-   :partnermx.net;42||2001::fefe
-.EE
-
-Note: 
-.I localip
-can be private IP address subject of NAT'ing.
-
-Additionally,
-.I smtproutes 
-allows to forward bounces (with a 'Nullsender' MAIL FROM: <>)
-literally expressed as '!@'
-to a particular bounce host:
-
-.EX
-   !@:bouncehost.af.mil;27
-.EE
-
-The
-.B qmail
-system does not protect you if you create an artificial
-mail loop between machines.
-However,
-you are always safe using
-.I smtproutes
-if you do not accept mail from the network.
-.TP 5
-.I timeoutconnect
-Number of seconds
-.B qmail-remote
-will wait for the remote SMTP server to accept a connection.
-Default: 60.
-The kernel normally imposes a 75-second upper limit.
-.TP 5
-.I timeoutremote
-Number of seconds
-.B qmail-remote
-will wait for each response from the remote SMTP server.
-Default: 1200.
-.TP 5
-.I tlsdestinations
-If present, this file advices
-.B qmail-remote
-to use TLS (optionally or mandatory) encryption for specific destination domains
-as provided by the forward-path and to validate/verify 
-the server certificate perhaps for a particular sender's domain:
-.I destination:cafile|ciphers|verifydepth;[s]port|domain 
-or
-.IR destination:=fingerprint|ciphers|verifydepth;[s]port|domain .
-Unless explicitely configured,
-.B qmail-remote 
-accepts any or no certificate provided by the server (opportunistic encryption)
-using the following (single character) rules:
-
-.EX
-   (0) *:  # Enable TLS but fallback to NOTLS (default);
-             server authentication is optional, given further settings
-.EE
-
-Special settings:
-
-.EX
-   (1) ?:  # fallthru to no TLS in case of TLS protocol errors (exceptional)
-   (2) -:  # allow anonymous connections
-   (3) /:  # disable TLSA lookup and verification
-.EE
-
-Double character rules instruct
-.B qmail-remote
-to require a STARTTLS or SMTPS connection (mandatory TLS):
- 
-.EX
-   (4) -*: # at least anonymous connections
-   (5) +*: # require and validate X.509 certs
-   (6) ~*: # cert + validate SAN/DN, however accept wildcard certs and partial matching
-   (7) =*: # cert + validate SAN/DN against FQDN
-   (8) /*: # don't do TSLA lookup and X.509 matching
-.EE
-
-Additionally, 
-.B qmail-remote 
-can be told to use per-domain connection settings: 
-
-.EX
-   (9) example.com:
-  (10) securityfirst.com:/etc/ssl/cafile|!SSLv2:HIGH
-  (11) remote.com:/etc/ssl/certdir/||3;465
-  (12) mx.partner.com:/etc/ssl/partnerca||2|mydomain.net
-  (13) =mx.myfriend.com:/etc/ssl/cacert||4
-  (14) ~wildneighbor.net:
-  (15) -adhonlydomain.com:||aNULL:!kRSA
-  (16) %peer.partner.com:=E44194C56EF.....
-  (17) !nosslhost.example.com:
-  (18) hiddenpartner.org:;35 
-  (19) ?tlsold.net: 
-  (20) /nodane.org: 
-.EE
-
-The ninth line requires from
-.B qmail-remote 
-to demand a STARTTLS connection for any destination
-address targeting domain
-.IR example.com .
-
-The tenth line accepts STARTTLS connections
-for
-.I securityfirst.com
-only, if the X.509 certificate can be verified against
-the CA cert as provided via
-.I /etc/ssl/cafile 
-and with the acceptable ciphers 
-.IR SSLv2:HIGH .
-
-Line number eleven tells 
-.B qmail-remote
-to use a 
-.I SMTPS
-connection on port
-.I 465
-to any host at
-.I remote.com
-and accept this host only, if the peer's cert
-can be validated against the CA certs available 
-in
-.I /etc/ssl/certdir/
-and does not exceed a verification depth of
-.IR 3 .
-
-Line twelve shows an example, how 
-.I tlsdestinations
-can be bound exclusively to a sender domain. In the shown case,
-only if
-.I mx.mydomain.net
-is used as sender domain, 
-a connection for the destination address
-.I mx.partner.com
-is mandatory secured by TLS with a CA cert available as
-.I /etc/ssl/partnerca 
-with a verification depth of
-.IR 2 .
-
-Furthermore, the sample on line thirteen demonstrates the case where 
-.B qmail-remote
-sees a destination address concatinated with
-.IR = .
-Now it will only accept the certificate,
-if the X.509's DN can be validated
-against the FQDN of the server (by means of a DNS lookup)
-and it verifies against the 
-.IR cacert
-CA certificate and does not exceed a verification depth of
-.IR 1 .
-
-In case a certain
-.I destination
-may use 'wildcard' domain names in the SAN/DN, 
-.B qmail-remote
-can cope with this (line fourteeen) 
-prepending the destination with a '~':
-.IR ~wildneighor.net .
-This mechanism also supports partial matching
-of SAN/DN and domain name.
-
-In the same sense (line fiveteen), 
-.B qmail-remote
-may accept TLS connections based on Anonymous DH (ADH)
-- where the server does not provide a cert for authentication -
-once the domain name is prepended with a 
-.I - 
-as key encryption cipher and discards 
-.I !RSA
-for authentication if told so.
-
-Certificate pinning for a particular 
-.I %host
-indicated by the leading character '%' is shown on line sixteen.
-Instead of the CA file, now the
-.I =fingerprint
-of the peer host certificate needs to be provided. 
-The X.509 fingerprint
-should prepended with an equal sign ('=') and to 
-be stripped from additional colons (':'). The fingerprint
-string is evaluated case-insensitive.  
-.BR qmail-remote 's
-certificate pinning supports SHA1, SHA224, SHA256, and SHA512
-digests, determined by the length of the fingerprint given.
-
-Note, that in this case, no TLSA validation is performed;
-it is thus a 'silent' verification'.
-.B qmail-remote
-can be instructed to omit the STARTTLS command for the recipient address
-.I nosslhost.example.com 
-as indicated with a leading 
-.I ! 
-as shown on line seventeen. This behavior can be relaxed (line nineteen) using
-.I ? 
-followed by a colon, a host, or domain name. Now 
-.B qmail-remote
-will initally try a TLS connection by however is alllowed to switch back
-to none-encryption mode, in case this is not possible due 
-protocol reasons. 
-
-.B qmail-remote
-allows an \'implicit TLS\' connection on any port, if 
-.I port
-is prended with an 
-.I s
-even without providing the port.
-
-In case, no particular ciphers or CA certs are
-required, a colon/semi-colon ':;' can be used as shortcut (line eighteen).
-Generally, any port can be provided after the semi-colon.
-If however, 
-.I port
-equals 
-.IR 465 , 
-SMTPS will be used instead of STARTTLS and if 
-.I port 
-equals 
-.IR 6209 , 
-QMTPS is the chosen transport protocol.
-The settings here overrule previous instructions.
-
-Finally, TLSA lookups can be disabled, prepending a
-domain name with
-.I /
-for the target domain as shown on line twenty.
-
-Note that 'destination' is subject of the
-forwarding rules as provided by
-.IR authsenders ,
-.IR qmtproutes  ,
-and
-.IR smtproutes .
-.SU "ADDENDUM"
-.B qmail-remote 
-needs to read the message from a file in order
-to announce the 
-.I SIZE
-in the SMTP dialogue.
-However, if called through a pipe, it will not
-provide this information to the receiving MTA.
-More severe, a delivery over
-.I QMTP(S)
-will fail.
-.SH "RETURN CODES"
-.B qmail-remote
-always exits
-.I 0
-for SMTP(S) delivery. 
-In case of QMTP(S)
-.I 1
-is returned in case a buffer feed fails and

-.TH s/qmail: qmail-send 8
-.SH NAME
-qmail-send \- deliver mail messages from the queue
-.SH SYNOPSIS
-.B qmail-send
-.SH DESCRIPTION
-.B qmail-send
-handles messages placed into the outgoing queue by
-.BR qmail-queue .
-It uses
-.B qmail-lspawn
-to deliver messages to local recipients and
-.B qmail-rspawn
-to deliver messages to remote recipients.
-If a message is temporarily undeliverable to one or more addresses,
-.B qmail-send
-leaves it in the queue and tries the addresses again later.
-
-.B qmail-send
-prints a readable record of its activities to descriptor 0.
-It writes commands to
-.BR qmail-lspawn ,
-.BR qmail-rspawn ,
-and
-.B qmail-clean
-on descriptors 1, 3, and 5,
-and reads responses from descriptors 2, 4, and 6.
-Communication with 
-.B qmail-todo
-is based on decriptors 7 and 8.
-.B qmail-send
-is responsible for avoiding deadlock.
-
-If
-.B qmail-send
-receives a TERM signal,
-it will exit cleanly, after waiting
-(possibly more than a minute)
-for current delivery attempts to finish.
-
-If
-.B qmail-send
-receives an ALRM signal,
-it will reschedule every message in the queue for immediate delivery.
-
-.SH "CONTROL FILES"
-.B WARNING:
-.B qmail-send
-reads its control files only when it starts.
-If you change the control files,
-you must stop and restart
-.BR qmail-send .
-Exception:
-If
-.B qmail-send
-receives a HUP signal,
-it will reread
-.IR locals ,
-.IR virtualdomains ,
-as well as
-.IR concurrencylocal ,
-.IR concurrencyremote ,
-and in addition
-.IR queuelifetime .
-.TP 5
-.I bouncefrom
-Bounce username.
-Default:
-.BR MAILER-DAEMON .
-.TP 5
-.I bouncehost
-Bounce host.
-Default:

-.B qmail-smtpd
-[
-.I checkprogram
-.I subprogram
-]
-.SH "DESCRIPTION"
-.B qmail-smtpd
-receives mail messages via the Simple Mail Transfer Protocol (SMTP)
-and invokes
-.B qmail-queue
-to deposit them into the outgoing queue.
-.B qmail-smtpd
-must be supplied with several environment variables;
-see
-.BR tcp-environ(5) .
-
-.B qmail-smtpd
-is responsible for counting hops.
-It rejects any message with 100 or more 
-.B Received
-or
-.B Delivered-To
-header fields.
-
-.B qmail-smtpd
-supports ESMTP and offers 8BITMIME, DATA, PIPELINING, SIZE, AUTH, STARTTLS, and SMTPUTF8 options.
-.B qmail-smtpd
-includes a 'Mail From:' parameter parser and obeys 'Auth', 'Size', and 'SMTPUTF8' advertisements.
-.B qmail-smtpd
-supports SMTPUTF8 SMTP envelope addresses and provides 8 bit clean message transmission.
-.B qmail-smtpd
-STARTTLS and SMTPS implementation requires the use of 
-.B sslserver
-from ucspi-ssl.
-
-Authentication is facilitated in case the environment variable 
-SMTPAUTH is set which tells
-.B qmail-smtpd
-to accept LOGIN, PLAIN, and eventually CRAM-MD5 Auth types
-and if additionally a PAM
-.I checkprogram 
-is available which reads on file descriptor 3 the username, a 0 byte, 
-the password or CRAM-MD5 digest/response derived from the SMTP client, 
-another 0 byte, a CRAM-MD5 challenge (if applicable to the Auth type),
-and a final 0 byte.
-.I checkprogram
-invokes
-.I subprogram
-upon successful authentication, which should return 0 to
-.BR qmail-smtpd ,
-effectively setting the environment variables RELAYCLIENT and 
-TCPREMOTEINFO or TCP6REMOTEINFO
-(any supplied value replaced with the authenticated username).
-.B qmail-smtpd
-will reject the authentication attempt if it receives a nonzero return
-value from
-.I checkprogram
-or
-.IR subprogram .
-
-STARTTLS support is enabled setting the environment variable UCSPITLS.
-In this case, 
-.B qmail-smtpd
-communicates with the
-.B sslserver
-program interface through a control socket, a reading and a writing pipe, dynamically
-defined during the session start to be used for transport layer encryption. 
-.B qmail-smtpd
-provides mutual authentication based on X.509 client certs and relaying 
-with additional SMTP Return-Path validation.
-
-.B qmail-smtpd
-may employ additional DNS look-ups for the 'Mail From:' envelope sender 
-address and/or the HELO/EHLO greeting string from the MTA client.
-
-.B qmail-smtpd 
-implements a SPF record check for the domain part of the received
-.I Mail-From:\ <return-path>
-address or
-the
-.I HELO/EHLO
-statement in case the domain information is missing.
-This behavior is triggered by the environment variable
-.BR SPF .
-
-.B qmail-smtpd
-can be advised to communicate with a Greylisting server prior of acceptance, like 
-.BR postgrey , 
-submitting the connection information
-.IR Mail\ From: ,
-.IR Rcpt\ To: ,
-.IR TCPREMOTEIP 
-and
-.I TCPREMOTEHOST 
-given its IPv4/IPv6 address as environment variable
-.IR POSTGREY
-and potentially including the port number (60000 is default) 
-following the IP address separated by a semi-colon.
-For IPv6 LLU addresses the interface name followwing a percent sign can be included:
-.IR fe80::1%eth0;60000 .
-A return value of
-.I 10
-will advise 
-.B qmail-smtpd 
-to defer the SMTP connection providing a
-.I 450\ greylisted\ (#4.3.0)
-response to the connecting MTA, which can be tailored (see below).
-This mechanism shall not be used for SMTP connections on the
-.I Submission
-port.
-Setting
-.I POSTGREY='-'
-disables the lookup.
-
-.SH "TRANSPARENCY"
-.B qmail-smtpd
-converts the SMTP newline convention into the UNIX newline convention
-by converting CR LF into LF.
-Usually, it returns a temporary error and drops the connection on bare LFs.
-
-.B qmail-smtpd
-accepts messages that contain long lines or non-ASCII characters
-and thus is initially capable for SMTPUTF8 support.

-.I badmailfrom
-Unacceptable envelope sender addresses.
-.B qmail-smtpd
-will reject every recipient address for a message
-if the envelope sender address is listed in
-.IR badmailfrom .
-A line in
-.I badmailfrom
-may be of the form
-.BR @\fIhost ,
-meaning every address at

-Additionally, any envelope sender address can be filtered
-with a wildmat check:
-
-.EX
-  *@earthlink.net
-  !fred@earthlink.net
-  [0-9][0-9][0-9][0-9][0-9]@[0-9][0-9][0-9].com

-.EE
-
-A
-.I badmailfrom
-file with this contents reject all mail from Earthlink except from
-fred@earthlink.net. It also rejects all mail with addresses like:
-12345@123.com and answerme@savetrees.com. Further, any mail with
-a sender address containing a percent sign (%) is rejected.
-
-This implementation recognises 'extended' addresss in 
-.I badmailfrom 
-allowing to reject mails with particluar spoofed domain addresses:
-
-(1) The address is appended with a '-'. 
-Now, if
-.I TCP(6)REMOTEHOST
-equals 'unknown', mails with the corresponding address are rejected
-(badmailfromunknown).
-
-(2) The address is appended with a '='.
-In case
-.I TCP(6)REMEOTEHOST
-is set mails, whose domain part of the envelope addresses 
-.B not 
-matching 
-the corresponding entry are rejected (badmailfromwellknown).
-
-(3) The address is appended with a '+'.
-If 
-.I RELAYCLIENT 
-is not set and the sender address matches a corresponding entry 
-(anti-spoofing for internal addresses).
-
-(4) The address is enhanced with a leading '~'.
-This requires a (left to right partial) matching of 
-.I TCP(6)REMOTEHOST 
-with the domain part of the envelope address.
-Thus, this specific entry in 
-.I badmailfrom 
-uses 
-.I TCP(6)REMOTEHOST
-in the first place (badmailfrommismachteddomains).
-
-(5) The address is enhanced with a leading '?'.
-Emails with the corresponding sender address pass by all further
-.I  badmailfrom
-tests including the
-.I MFDNSCHECK 
-check.
-
-Note: The 'enhanced' addresses are not subject of the wildmat check
-and are evaluated in lower-case.
-
-The wildmat check is done in the order: 
-Least significant to most significant.

-compatible Plugable Authentication Modules
-(PAM), receiving the envelope address on FD 3
-as 'recip@domain\\0\\0\\0' and returning '0'
-in a case of success and '1' in case of failure.
-The use of a PAM is indicated with a delimiting '|' and
-it will be called with up to five additional parameters;
-while a cdb follows a ':', which can be omitted.
-
-The list of external sources is consulted line-by-line for each
-recipient envelope address until the first positive answer,
-or a final negative response is encountered.
-Which external source to be queried, depends on the domain part of the
-recipient envelope address specified on the left side of the
-.I recipients
-file, while the external resource is provided right from the delimitor.
-
-The addresses' domain part is evaluated in lower-case.
-An exact domain match can be encompassed by means of a leading '@'.
-The '*' is a generic wildcard for all domains.
-Specific domains can be excluded from the lookup by means of a
-leading '!'; thus all recipient addresses are accepted for this domain.
-Additionally, a '!*' can be used as wildcard for all domains not encountered
-before in

-As 'last resort', it is possible to include SPF local rules here 
-(on one line), that will be applied before other SPF rules would fail.  
-This can be used to allow certain MX to send mails anyway. Example:
-
-.EE
-include:spf.trusted-forwarder.org
-.EX
-.TP 5
-.I timeoutsmtpd
-Number of seconds
-.B qmail-smtpd
-will wait for each new buffer of data from the remote SMTP client.
-Default: 1200.
-
-.SH "CONDITIONAL CONTROL FILES"
-The control files \fIrcpthosts\fR, \fImorecpthosts\fR, 
-\fIrecipients\fR, \fIbadhelo\fR 
-are 'conditional' control files and evaluated 
-only if the environment variable RELAYCLIENT is not set. 
-On the other hand,
-\fImailfromrules.cdb\fR is only taken into account, if
-RELAYCLIENT is set.
-This allows 
-.B qmail-smtpd
-to relay mail messages from local clients and to filter 
-mails with certain SMTP envelope conditions
-originating from particular clients ('Split Horizon').
-Other conditional control files are 
-\fIbadloadertypes\fR, 
-\fIbadmimetypes\fR
-which depend on the setting of the corresponding 
-environment variables.
-
-Further, the control files \fIspfexplain\fR and 
-\fIspflocalrules\fR are only evaluated if the 
-environment variable 
-.I SPF
-is defined and greater than 0 and 
-.I RELAYCLIENT
-is not set. 
-
-.SH "ENVIRONMENT VARIABLES READ"
-Environment variables may be defined globally in the
-.B qmail-smtpd 
-startup script and/or individually as part of the
-.BR sslserver 's
-cdb database.
-The environment variables may be quoted ("variable", or 'variable') and
-in case of global use, have to be exported.
-.B qmail-smtpd
-supports the following legacy environment variables, typically
-provided by
-.B sslserver
-or
-.B tcpserver:
-.IR TCP(6)REMOTEIP ,
-.IR TCP(6)REMOTEHOST 
-.IR TCP(6)REMOTEINFO 
-and 
-.IR TCPLOCALPORT
-as well as
-.IR RELAYCLIENT .
-Additionally, 
-.B qmail-smtpd
-may use several environment variables for different purposes.
-.P
-Controlling the SMTP HELO/EHLO:
-.IP
-.TP 5
-.I HELOCHECK=''
-enables a check of the provided HELO/EHLO greeting against
-the content of the control file
-.IR badhelo .
-In case no HELO/EHLO greeting is given, SMTP
-connections can be rejected, if
-.I HELOCHECK='!'
-is set. Checks on the presence and the content of
-the HELO/EHLO greeting string is facilitated, setting
-.IR HELOCHECK='.' .
-To enforce the match of the HELO/EHLO greeting with 
-the remote host's FQDN (
-.IR TCP(6)REMOTEHOST ), 
-use
-.IR HELOCHECK='=' .
-.TP 5
-.I HELOCHECK='A' | HELOCHECK='M'
-enable DNS A/MX lookup for the HELO/EHLO greeting string.
-In addition, the HELO/EHLO string is checked against 
-the content of
-.IR badhelo .
-.TP 5
-.I UTF8
-display the 
-.I SMTPUTF8
-greeting string. This is off by default.
-.p
-Since
-.B qmail-smtpd
-is 8 bit clean, setting of
-.I UTF8 
-has no real consequences except for displaying this
-setting in the log as
-.IR ESMTP[SA]UTF8 .
-.P
-Controlling the SMTP Mail From:
-.IP
-.TP 5
-.I LOCALMFCHECK
-is used to enable a 'Mail From:' address Verification (MAV) for RELAYCLIENTs.
-Thus, the domain part of the 'Mail From:' envelope sender address
-has to match an entry in
-.IR rcpthosts
-or
-.IR morercpthosts
-control files, if not explicitly defined otherwise.
-
-If LOCALMFCHECK='!' is set, the control file
-.I mailfromrules.cdb
-is evaluated and the MAV is facilitated employing the environment variables
-.IR TCP(6)REMOTEINFO ,
-.IR TCP(6)REMOTIP ,
-or
-.I TCP(6)REMOTEHOST
-as a key.
-However, if LOCALMFCHECK='=' is provided, 
-.IR TCP(6)REMOTEINFO 
-(i.e. set by Auth) has to match the 'Mail From:' 
-envelope address (case insensitive).
-Alternativley, using LOCALMFCHECK='?' the email address
-embedded in the DN of a X.509 client is used and compared 
-against the 'Mail From:' envelope address.
-Of course, this requires
-.B sslserver
-to request a client cert for mutual authentication.
-
-Note: Adding a qualifier to LOCALMFCHCEK,
-the domain part of the 'Mail From:' address is compared
-against the provided string.
-.TP 5
-.IR MFDNSCHECK
-enable DNS MX lookup for the domain part of the 'Mail From:' envelope sender address.
-.TP 5
-.I SPF='0'|'1'|'2'|'3'|'4'|'5'|'6'
-SPF Records will be evaluated for the current SMTP session in case
-.B SPF
-is defined. The value of 
-.B SPF
-may be given between 1 and 6 to enable SPF checks.
-.I 1 
-selects 'annotate-only' mode, where
-.B qmail-smtpd
-will annotate incoming email with a
-.B Received-SPF
-header, but will not reject any messages.  
-.I 2 
-will produce temporary failures on DNS lookup problems 
-so you can be sure always to have a meaningful Received-SPF header.  
-.I 3 
-selects 'reject' mode, where incoming mail will be rejected 
-if the SPF record says 'fail'.  
-.I 4
-selects a more stricter rejection mode, which is like 'reject' mode,
-except that incoming mail will also be rejected, when the SPF record
-says 'softfail'. Further,
-.I 5 
-will reject when the SPF record says 'neutral', and 
-.I 6 
-rejects, if no SPF records are available at all 
-(or a syntax error was encountered).
-If 
-.B SPF 
-is given as 
-.IR 0 ,
-SPF checks are disabled.
-
-Note: Additional control files are
-.I spfexplain 
-and
-.IR spflocalrules .
-
-.P
-Controlling the SMTP RCPT TO:
-.IP
-.TP 5
-.I MAXRECIPIENTS
-is the number of Rcpt To:'s
-.B qmail-smtpd
-will accept in a SMTP session.
-If MAXRECIPIENTS ist not set, any number is allowed.
-.TP 5
-.IR TARPITCOUNT
-is the number of Rcpt To:
-.B qmail-smtpd
-accepts before it starts tarpitting.
-Default: 0 which means no tarpitting.
-.TP 5
-.IR TARPITDELAY
-tarpitdelay is the time in seconds of delay
-to be introduced after each subsequent Rcpt To:.
-
-Smart Rejection Notes:
-If
-.IR TARPITCOUNT
-is set and
-.IR TARPITDELAY
-= 0 (default)
-.B qmail-smtpd
-will issue after recognising
-.IR TARPITCOUNT
-invalid Rcpt To: a Recipient failure;
-thus additional Rcpt Tos will not be accepted.
-If, however
-.IR TARPITCOUNT
-is set and
-.IR TARPITDELAY
-= 999
-.B qmail-smtpd
-will issue after
-.IR TARPITCOUNT
-invalid Rcpt To: a Recipient failure
-.TP 5 
-.I RECIPIENTS450
-tells
-.b qmail-smtpd
-to issue a SMTP reply '450' (temporary rejection) 
-instead the default '550'
-in case the recipient was not listed in any
-.I recipients 
-cdb.
-
-.P
-Controlling the email body:
-.IP
-.TP 5
-.I BADLOADERTYPE='c'
-tells
-.B qmail-smtpd
-to evaluate the control file
-.I badloadertypes.cdb
-with the starting string 'c'.
-If 
-.I BADLOADERTYPE='-'
-is set, the check is disabled.
-In case
-.I BADLOADERTYPE='+'
-is defined, the check is disabled for
-.IR RELAYCLIENTS .
-.TP 5
-.I BADMIMETYPE
-see control file
-.IR badmimetypes.cdb .
-In case
-.I BADMIMETYPE='-'
-is set; 
-.I badmimetypes.cdb 
-is not considered; thus the check is disabled.
-Setting
-.I BADMIMTETYPE='!'
-the mime type is rejected if it includes whitespaces;
-even without the control file
-.IR badmimetypes.cdb .
-Providing
-.I BADMIMTETYPE='+'
-the check is disabled if in addition
-.IR RELAYCLIENTS 
-are recognized.
-
-.TP 5
-.I BASE64
-tells QHPSI to enable virus checking only if a base64 encoded
-attachment was identified.
-.TP 5
-.I DATABYTES
-see control file
-.IR databytes .
-.TP 5
-.I QHPSI
-is used by 
-.B qmail-smtpd
-to supply the name of the virus scanner and it's path.
-.P
-Environment variables for SMTP authentication: 
-.IP
-.TP 5
-.I SMTPAUTH
-is used to enable SMTP Authentication for the 
-Auth types
-LOGIN and PLAIN.
-In case
-.TP 5
-.I SMTPAUTH='+cram'
-is defined,
-.B qmail-smtpd
-honors LOGIN, PLAIN, and additionally CRAM-MD5 authentication.
-Simply
-.TP 5
-.I SMTPAUTH='cram'
-restricts authentication just to CRAM-MD5.
-If however
-.TP 5
-.I SMTPAUTH='!'
-starts with an exclamation mark, Auth is required. 
-You can enforce 'Submission' using this option 
-and binding
-.B qmail-smtpd
-to the SUBMISSION port \'587'\.
-In particular,
-.TP 5
-.I SMTPAUTH='!cram'
-may be useful.
-In opposite, if
-.TP 5
-.I SMTPAUTH='-'
-starts with a dash, Auth disabled for particular
-connections.
-Note: The use of 'cram' requires a CRAM-MD5 enabled PAM.
-.P
-Setting up the TLS/STARTTLS environment:
-.IP
-.TP 5
-.I UCSPITLS
-enables encrypted SMTP communication 
-via STARTTLS in case 
-.B sslserver
-is provided.
-If
-.I UCSPITLS='!'
-is set, STARTTLS is required; while setting
-.I UCSPITLS='-'
-disables STARTTLS.
-Further, 
-.I UCSPITLS='?'
-may be used to force the client to present a X.509 cert 
-for authentication purpose which may be refined 
-requesting
-.I UCSPITLS='@' 
-to additionally fetch the email address
-from the client's cert to be perhaps subject of 
-.IR LOCALMFCHECK .
-.P
-Other environment variables used:
-.IP
-.TP 5
-.I DELIVERTO
-mail address for special recipients.
-.TP 5
-.I RBLSMTPD
-feed from 
-.B rblsmtpd
-including the information received from the
-inquired RBL hosts and displayed as
-.I X-RBL-Info: 
-message header.
-.TP 5
-.I POSTGREY
-triggering the call of
-.B qmail-postgrey
-and feeding it with the IP address and port of the 
-.I greylisting
-server. If 
-.I POSTGREY 
-is set to
-.I -
-no lookup is performed.
-
-.SH "CUSTOMIZABLE RETURN MESSAGES"
-In case of rejected or defered SMTP connections
-.B qmail-smtpd
-can provide additional informations in the SMTP reply message
-which are sandwiched between the reply code and the EMMSC.
-.B qmail-smtpd
-recognizes these environment variables:
-.TP 5
-.I REPLY_GREYLISTED
-following 450 greylisting
-.TP 5
-.I REPLY_HELO
-following 550 Bad Helo
-.TP 5
-.I REPLY_MAILBOX

-.SH NAME
-qmail-todo \- schedule state change of message for delivery
-.SH SYNOPSIS
-.B qmail-todo
-.SH DESCRIPTION
-.B s/qmail 
-with a high local and remote concurrency number 
-is able to deliver a tremendous amount of messages (throughput).
-Depending on the provided resources however,
-often this can not be achieved since
-.B qmail-send
-becomes a bottleneck on delivery.
-
-.B qmail-send 
-preprocesses all new messages before deploying them for 
-.I local
-or for 
-.I remote 
-delivering. In a particulur run,
-.B qmail-send 
-does one 'todo' processing, but has the ability to close multiple jobs. 
-Due to this layout, potentially 
-.B qmail-send 
-can not feed all the new available (local/remote) delivery slots 
-and therefore, it is not possible to achieve the maximum throughput.
-
-This is a minor problem, given
-.B qmail-send 
-is able to complete this in short time; but due to
-many file system calls (fsync and (un)link) a 'todo'
-run is expensive and throttles the throughput.
-
-.B qmail-todo
-solves this 'silly qmail (queue) problem'
-which is apparent only on system with high injection rates,
-delegating the scheduling of 'todo' runs to a dedicated process.
-
-.SH "COMMUNICATION"
-.B qmail-todo
-interfaces with 
-.B qmail-send
-on file descriptors \fI[1,8]\fR on sending
-and \fI[7,0]\fR for receiving. 
-.B qmail-todo 
-communicates with
-.B qmail-clean
-on file descriptors \fI[2,0]\fR for sending
-and \fI[3,1]\fR for receiving.
-
-.B qmail-todo 
-and
-.B qmail-send
-share an extended and peristent message exchange format:
-
-.EX
-D[LRB]<mesgid>\0
-  Start delivery for new message with id <messid>.
-  The character L, R or B defines the type
-  of delivery: Local, Remote, or Both, respectively.
-.EE
-
-.EX
-L<string>\0
-  Dump string to the logger without adding additional
- '\\n' or similar.
-.EE
-
-.B qmail-todo 
-sends "\\0" terminated messages, whereas 
-.B qmail-send 
-just sends one character to

-.SH NAME
-qmail-users \- assign mail addresses to users
-.SH OVERVIEW
-The file
-.B SQMAIL/users/assign
-assigns the local part of mail addresses to users. For example,
-
-.EX
-   =joe.shmoe:joe:503:78:/home/joe:::
-.EE
-
-says that mail for
-.B joe.shmoe
-should be delivered to user
-.BR joe ,
-with uid 503 and gid 78,
-as specified by
-.BR /home/joe/.qmail .
-
-Assignments fed to
-.B qmail-newu
-will be used by
-.B qmail-lspawn
-to control
-.BR qmail-local 's
-deliveries.
-Use
-.B qmail-newu (8)
-to generate
-.I users/assign.cdb
-from
-.IR users/assign .
-A change to
-.B SQMAIL/users/assign
-will have no effect until
-.B qmail-newu
-is run.
-.SH STRUCTURE
-.B SQMAIL/users/assign
-is a series of assignments, one per line.
-It ends with a line containing a single dot.
-Lines must not contain NUL.
-.SH "SIMPLE ASSIGNMENTS"
-A simple assignment is a line of the form
-
-.EX
-   =local:user:uid:gid:homedir:dash:ext:
-.EE
-
-Here
-.I local
-is an address;
-.IR user ,
-.IR uid ,

-
-If there are several assignments for the same
-.I local
-address,
-.B qmail-lspawn
-will use the first one.
-
-.I local
-is interpreted without regard to case.
-.SH "WILDCARD ASSIGNMENTS"
-A wildcard assignment is a line of the form
-
-.EX
-   +loc:user:uid:gid:homedir:dash:pre:
-.EE
-
-This assignment applies to any address beginning with
-.IR loc ,
-including
-.I loc
-itself.
-It means the same as
-
-.EX
-   =locext:user:uid:gid:homedir:dash:preext:

-
-for every string
-.IR ext .
-
-A more specific wildcard assignment overrides a less specific

-
-.SH "SYNOPSIS"
-.B qmail-vmailuser
-.I [homedir]
-.I [-C]
-.SH "DESCRIPTION"
-.B qmail-vmailuser
-is a maildir verification PAM supporting 
-.I VMailMgr 
-and 
-.I Vpopmail 
-users for virtual domains.
-Invoked via 
-.BR qmail-smtpd 's
-recipient mechanism, it checks the
-existence of the recipient directory
-for the provisioned virtual users in
-.IR SQMAIL/control/virtualusers . 
-
-.B qmail-vmailuser
-follows 
-.BR checkpassword 's
-interface specification evaluating the 
-SMTP forwarding path (RCPT TO:) taken from 
-discriptor 3 with a length of max 128 bytes.
-
-The forwarding path 
-.I vuser@domain
-is tokenized to determine the 
-virtual user in
-.I SQMAIL/control/virtualusers
-given by
-.I domain
-in the first step and then validating for
-.I vuser
-the existance of (v)user's mail directory
-in lower case while substituting dots by colons.
-.SH "USAGE" 
-.B qmail-vmailuser
-is called as PAM from
-.BR qmail-smtpd 's
-control file
-.IR SQMAIL/control/recipients :
-
-.EX
-  domain|bin/qmail-vmailuser
-  *|bin/qmail-vmailuser /homedir -C
-.EE
-
-No specific settings are required to support
-either 
-.I VMailMgr 
-or 
-.IR Vpopmail , 
-except for the 
-.I homedir 
-and perhaps the option
-.I -C
-evaluating 
-.I vuser 
-in case respect mode.
-Since
-.I homedir 
-defaults mostly to
-.IR /home ,
-this argument can be omitted.
-.SH "SECURITY"
-For successfull operation
-.B qmail-vmailuser
-requires to stat
-.IR vuser 's
-directory though without reading 
-it's actual contents. Due to
-restrictions given by 
-.IR Vpopmail ,
-.B qmail-vmailuser
-needs to belong to 
-.I vpopmail:vchkpw
-or gnerally to be
-root-owned and 'sticky'.
-.SH "RETURN CODES"
-If for the provided
-.I vuser@domain
-the user directory does not exist
-.B qmail-vmailuser
-exits 1.
-If
-.B qmail-vmailuser
-is misused, it may instead exit 2.
-If there is a temporary problem,
-.B qmail-vmailuser
-exits 111.
-In case

-.TH s/qmail: setforward 1
-.SH NAME
-setforward \- create a forwarding database
-.SH SYNOPSIS
-.B setforward
-.I cdb
-.I tmp
-.SH DESCRIPTION
-.B setforward
-reads a table of forwarding instructions from its standard input.
-It converts the table into a forwarding database.
-The forwarding database can be used by
-.BR fastforward .
-
-.B setforward
-writes the forwarding database to
-.IR tmp ;
-it then moves
-.I tmp
-to
-.IR cdb .
-.I tmp
-and
-.I cdb
-must be on the same filesystem.
-
-If there is a problem creating
-.IR tmp ,
-.B setforward
-complains and leaves
-.I cdb
-alone.
-
-The forwarding database format is portable across machines.
-.SH "INSTRUCTION FORMAT"
-A forwarding instruction contains a
-.I target\fR,
-a colon, a series of commands, and a semicolon.
-Each command is a
-.I recipient address\fR,
-.I owner address\fR,
-.I external mailing list\fR,
-or
-.I program\fR.
-Commands are separated by commas.
-
-For example,
-
-.EX
-   root@yp.to: god@heaven.af.mil, staff@af.mil;
-.EE
-
-says that mail for
-.B root@yp.to
-should be forwarded to the recipient addresses
-.B god@heaven.af.mil
-and
-.BR staff@af.mil .
-
-When
-.B setforward
-sees # it ignores all text from # to the end of the line:
-
-.EX
-   # this is a comment
-.EE
-
-.B setforward
-ignores all other line endings,
-so you can split a forwarding instruction across lines.
-It also ignores spaces and tabs.
-Exception:
-you can put a space (or tab or comma or whatever)
-into a target or command by putting a backslash in front of it.
-(However, NUL bytes are not permitted anywhere.)
-.SH "TARGETS"
-When
-.B fastforward
-sees the incoming address
-.IR user@host.dom ,
-it tries three targets:
-.IR user@host.dom ,
-.IR @host.dom ,
-and
-.IR user@ .
-It obeys the commands for the first target that it finds.
-Target names are interpreted without regard to case.
-
-All the commands for a single target must be listed in a single instruction.
-Exception: an owner address can be listed in a separate instruction.
-.SH "RECIPIENT ADDRESSES"
-If a command begins with an ampersand,
-.B setforward
-takes the remaining bytes in the command as a recipient address:
-
-.EX
-   boss@yp.to: &god@heaven.af.mil;
-.EE
-
-.B fastforward
-sends each incoming mail message
-to the recipient address.
-The recipient address must include a fully qualified domain name.
-It cannot be longer than 800 bytes.
-
-If a recipient address is itself a target in the forwarding table,
-.B fastforward
-will recursively handle the instructions for that target.
-Note that
-.I @host.dom
-and
-.I user@
-wildcards do not apply here;
-they apply only to the incoming address.
-
-If a command begins with a letter or number,
-.B setforward
-takes the entire command as a recipient address:
-
-.EX
-   boss@yp.to: god@heaven.af.mil;
-.EE
-.SH "OWNER ADDRESSES"
-If a command begins with a question mark,
-.B setforward
-takes the remaining bytes in the command as an owner address:
-
-.EX
-   sos@heaven.af.mil: ?owner-sos@heaven.af.mil;
-.EE
-
-.B fastforward
-uses that address as the envelope sender for forwarded mail,
-so bounces will go back to that address.
-(Normally, if a message is forwarded to a bad address,
-it will bounce back to the original envelope sender.)
-.SH "EXTERNAL MAILING LISTS"
-If a command begins with a dot or slash,
-.B setforward
-takes the entire command as the name of a binary mailing list file created by
-.BR setmaillist :
-
-.EX
-   sos@heaven.af.mil: /etc/lists/sos.bin;
-.EE
-
-.B fastforward
-will read and obey the commands in that file.
-The file must be world-readable
-and accessible to
-.BR fastforward .
-.SH "PROGRAMS"
-If a command begins with a vertical bar or exclamation point,
-.B setforward
-takes the rest of the command as the name of a program to run:
-
-.EX
-   dew@: |dew-monitor;
-.EE
-
-For a vertical bar,
-.B fastforward
-feeds the message
-to that program.
-An exclamation point works the same way except that
-.B fastforward
-inserts
-.BR $UFLINE ,
-.BR $RPLINE ,
-and
-.B $DTLINE
-in front of the message.
-.SH "DUPLICATES"
-When
-.B fastforward
-is building the recipient list for a message,
-it keeps track of the recipient addresses and external mailing lists
-it has used.
-If the same command shows up again, it skips it.
-For example:
-
-.EX
-   everybody@yp.to: programmers@yp.to, testers@yp.to;
-   programmers@yp.to: joe@yp.to, bob@yp.to;
-   testers@yp.to: joe@yp.to, fred@yp.to;
-.EE
-
-A message to
-.B everybody@yp.to
-will be sent to
-.B joe@yp.to
-only once.
-(This also means that addresses in an internal forwarding loop
-are discarded.)
-
-Exception:
-If a target has an owner address,
-commands for that target are considered different
-from commands for ``outside'' targets.

-.SH DESCRIPTION
-.B srsforward
-forwards mails for dedicated recipient
-.I srsdomains 
-to the specified list of addresses
-while extending the SMTP 'RCPT TO:' envelope address with 
-SRS (Sender Rewriting Scheme) information.
-It is a simple wrapper around
-.B qmail-queue 
-rewriting the SMTP recipient address. The forwarded email
-ought to be acceptable for SPF enabled recipient MTAs. 
-Additionally, it mitigates the forgery of addresses for bounces.
-.SH "CONTROL FILE"
-.B srsforward 
-reads the control file 
-.IR srsdomains .
-Here, you can specify 
-
-.I srsdomain:SRS_secret1 SRS_secret2 ...|[+,-,=]|[srsaddress(.)]
-
-.I srsdomain
-is 
-.B s/qmail's 
-recipient domain; typically
-.I defaultdomain 
-or any domain given in
-.IR rcpthosts .
-.I srsdomain 
-can be simply expressed as '*', thus the
-following informations are
-applicable for all 
-.B srsfoward
-domains as default values, while
-particular 
-.I srsdomain 
-settings have precedence.
-Reversely, recipient
-domains can be disable for SRS fowarding:
-.IR !nosrsfoward.example.com: .
-
-.B srsforward
-accepts several 'secrets' for each
-.I srsdomain
-separated by empty spaces. 
-
-.BR srsfoward 's
-.I delimiter
-is a character chosen out of the set
-.I +,-,=
-with default
-.I = 
-and thus is optional.
-
-.B srsforward
-may include
-.I srsaddress
-to construct the domain part of the RCPT TO:
-envelope address for SRS fowarded mails. If 
-.I srsaddress 
-ends with a dot '.',
-this name is used to prepend the original 
-host name and typically is chosen as
-.IR srs. .
-Otherwise, the original host name is
-used as default 
-.I srsaddress 
-for forwarding and also relevant for 
-potential bounces being subject of

-and to forward the bounce mail to its original address.
-.SH "SRS DOMAINS"
-In order to accept emails for SRS modified
-return addresses, you need to setup those in
-.IR rcpthosts .
-If your domain is
-.I example.com
-in
-.I rcpthosts
-you probably want to set up additionally
-.IR srs.example.com .
-However, 
-.I .example.com
-would be fine as well.
-.SH "VIRTUAL SRS USER"
-SRS can facilitate a virtual user typically named
-.I srs
-and thus requires an entry like
-.I srs.example.com:srs 
-in
-.IR virtualdomains .
-.SH "DOT QMAIL"
-.B srsreverse
-is called from a 
-.I dot-qmail
-file which could be
-.IR SQMAIL/alias/.qmail-srs-default .
-.SH "CONTROL FILES"
-.B srsreverse
-reads the control file 
-.I virtualdomains
-to exfiltrate the (virtual) SRS user name for the received domain, 
-if given. With the evaluated
-.IR srsdomain ,
-.B srsrevers
-fetches the
-.I SRS secret
-from 
-.I srsdomains 
-in order to validate the SRS bounce address.
-.SH "ENVIRONMENT VARIABLES"
-.B srsrverse 
-reads the environment variables
-.IR DTLINE ,
-.IR HOST ,
-and
-.IR RECIPIENTS .
-.I HOST 
-is used to determine the 
-.IR srsdomain .
-The forwarding bounce address is reconstructed from
-the local part of 
-.IR RECIPIENTS .
-.SH VERP
-The Sender Rewriting Scheme SRS can be considered 
-as tailored form of VERP: Variable Envelope Return Path. 
-The chosen primary delimiter
-.I =
-is recognized by

-* Generating Ed25519 signed message:
-*
-* 1. RSA SHA1/SHA256 signatures are generated in streaming mode together with
-*    their hashes. Two different 'contexts' (ctx) are used here:
-*    m_Hdr_shaXctx      => Used for signing (EVP_Sign...) -- covering the header only
-*    m_[B,E]dy_shaXctx  => Used for hashing (EVP_Digest..) -- covering the body only
-*
-* 2. Private keys
-*    For hybrid signing we need two distinct keys:
-*    - RSAKey
-*    - ECCKey
-*    These private keys needs to be passed concurrently to the signature functions.
-*    Given those keys, the signature operation itself is executed in one step.
-*
-* 3. Public keys
-*    The 'public keys' need to be deployed in the DNS:
-*    - The RSA public key is DER-header enriched base64-encoded; thus is 9 byte larger
-*      than the 'naked' public key, which size depends on the given parameters. 
-*    - The Ed25519 public key is also base64-encoded with a constant length of 60 byte.
-*
-* 4. DKIM message preparation scheme 
-*    According to RFC 6376 Sec. 3.7, we have a conducted hash for
-*    - the previously available headers in the message; 
-*      selected and given in order by h=...,
-*    - any existing DKIM signature fields b=...,
-*    - except for previous added 'X-Authentication ...' header fields,
-*    - and all (new) synthezised DKIM header tokens; except of course for the 
-*      signature itself - treated as 'null string': b="".
-*    All this is subject of canonicalization (adding/removing CRLF, whitespaces ...).
-+    As a result, the input for further calculations depends on this order given.
-*
-*    Results following the 'preparation scheme':
-*    -  The message body hash is included in the DKIM header   => bh=[m_[B,E]dy_shaXctx].
-*    -  The message signature (including the result of bh=...) =>  b=[m_Hdr_shaXctx]
-*
-*    We consider SHA256 as default hash function and SHA1 as exception (on demand).
-*
-* 5. Generating (ECC) signatures
-*    According to RFC 8032 Sect 4., we have two possible Ed25519 signature schemes:
-*
-*    a) PureEd25519, as a one shot signature calculation swallowing the 
-*       complete message and employing a shortened SHA-512 hash input.
-*    b) HashEd25519 working again in 'streaming mode' and permitting a choice 
-*        for the hash function - which is in RFC 8463 - defined to be SHA-256.
-*
-*    RFC 8463 in Sect 3 is a bit ambiguous about the signing function:
-*    Ed25519-256 vs. PureEd25519. 
-*    In fact (after consulting John Levine), it is PureEd25519.
-*
-*    In order to allow parallel RSA/Ed25519 processing, we need to generate:
-*    m_Hdr_sha256ctx  => Used for RSA signatures
-*    m_Bdy_sha256ctx  => The SHA256 hash of selected header parts and body (RSA)
-*    m_Edy_sha256ctx  => The SHA256 hash of selected header parts and body (Ed25519)
-*    m_Hdr_ed25519ctx => The signature of the messsage header using PureEd25519
-*                        following the 'preparation' scheme
-*
-*    Now, two cryptographic informations are provided in the header:
-*    bh=[m_Edy_sha256ctx]  => The SHA256 digest of the message (BodyHash),
-*     b=[m_Hdr_ed25519ctx] => The PureED25519 signature.
-*                             including the value of bh=... (EmailSignature)
-*                             having a length of 512 bits => 64 bytes.
-*
-* 6. Hybrid signatures (RSA and Ed25519)
-*    They involve 
-*    m_Hdr_sha256ctx  => Used for RSA signatures
-*    m_Hdr_ed25519ctx => PureED25519 signature
-*    m_Bdy_sha256ctx  => SHA256 digest of the message (BodyHash) for RSA
-*    m_Edy_sha256ctx  => SHA256 digest of the message (BodyHash) for Ed25519
-*
-*    The EVP_DigestFinal routine has to be replaced by EVP_DigestFinal_ex.
-*    However; after the first call, its content seems to be garbeled.
-*    A common MD for both RSA and Ed2551 seems to be infeasible.
-*
-* ------
-*
-* The particular function and variable names chosen here do not obviously match 
-* what they are intended to do. However, in order to keep traceablility of the 
-* changes, I left those untouched.

-/** @file qmail-dksign.c -- generate signature and attach in DKIM header to outgoing message
-
-    Steps:
-    ------
-    a) DKIM controls:  get private key for sending domain
-    b) Prepare two staging files at queue/dkim (before and after signing)
-    c) Read input at fd0 and insert CR for every line and store at dkim/x/pre
-    d) DKIM sign the message with provided private key and store at dkim/y/post
-    e) Copy signed file from fd to 0
-    f) Invoke qmail-remote (respecting the \r\n)
-    g) Remove staging files (pre/post)
-
-    Hack for hybrid signatures:
-    ---------------------------
-
-    a) selector is a link to RSA private key
-    b) selector2 is a link to Ed25519 private key
-    c) Both are provided in the 'selector' field of dkimdomains separated by colon
-    d) The coupled selector information is provided to qmail-dkim as: -yselector ,-Yselector2
-    e) The RSA privat key is given unaltered
-    f) The Ed25519 private is supplied as additional argument

-/*** wildmat.c.orig	Wed Dec  3 11:46:31 1997 */
-/*  $Revision: 1.1 $
-**
-**  Do shell-style pattern matching for ?, \, [], and * characters.
-**  Might not be robust in face of malformed patterns; e.g., "foo[a-"
-**  could cause a segmentation violation.  It is 8bit clean.
-**
-**  Written by Rich $alz, mirror!rs, Wed Nov 26 19:03:17 EST 1986.
-**  Rich $alz is now <rsalz@osf.org>.
-**  April, 1991:  Replaced mutually-recursive calls with in-line code
-**  for the star character.
-**
-**  Special thanks to Lars Mathiesen <thorinn@diku.dk> for the ABORT code.
-**  This can greatly speed up failing wildcard patterns.  For example:
-**	pattern: -*-*-*-*-*-*-12-*-*-*-m-*-*-*
-**	text 1:	 -adobe-courier-bold-o-normal--12-120-75-75-m-70-iso8859-1
-**	text 2:	 -adobe-courier-bold-o-normal--12-120-75-75-X-70-iso8859-1
-**  Text 1 matches with 51 calls, while text 2 fails with 54 calls.  Without
-**  the ABORT code, it takes 22310 calls to fail.  Ugh.  The following
-**  explanation is from Lars:
-**  The precondition that must be fulfilled is that DoMatch will consume
-**  at least one character in text.  This is true if *p is neither '*' nor
-**  '\0'.)  The last return has ABORT instead of FALSE to avoid quadratic
-**  behaviour in cases like pattern "*a*b*c*d" with text "abcxxxxx".  With
-**  FALSE, each star-loop has to run to the end of the text; with ABORT
-**  only the last one does.
-**
-**  Once the control of one instance of DoMatch enters the star-loop, that
-**  instance will return either TRUE or ABORT, and any calling instance
-**  will therefore return immediately after (without calling recursively
-**  again).  In effect, only one star-loop is ever active.  It would be
-**  possible to modify the code to maintain this context explicitly,
-**  eliminating all recursive calls at the cost of some complication and
-**  loss of clarity (and the ABORT stuff seems to be unclear enough by
-**  itself).  I think it would be unwise to try to get this into a
-**  released version unless you have a good test data base to try it out
-**  on.
