+.TH s/qmail: srsforward 1
+.SH NAME
+srsforward \- forward mail to one or more addresses including a SRS extension
+.SH SYNOPSIS
+in
+.BR .qmail :
+.B |srsforward
+.I address ...
+.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
+.BR srsreverse .
+.SH "ENVIRONMENT VARIABLES"
+.B srsforward
+reads the environment variables
+.IR HOST ,
+which is used to determine the 
+.IR srsdomain ,
+.IR DTLINE ,
+and 
+.IR NEWSENDER .
+.SH REFERENCE
+.B srsforward 
+uses srs2.c from 
+.IR libsrs2 .
