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 + + +Visit https://www.fehcom.de/sqmail/sqmail.html to +access online man-pages and documentation. + +Date: January, 14th 2024 (feh) |
