Postfix VERP support
====================
Postfix supports variable envelope return path addresses, which
means that each recipient receives a customized copy of the message,
with the recipient address encoded in the envelope sender address.
This concept was popularized by the qmail MTA and by the ezmlm
mailing list manager.
When VERP style delivery is requested, Postfix delivers mail with
sender address prefix@origin for a recipient user@domain, with a
sender address that encodes the recipient as follows:
prefix+user=domain@origin
so that undeliverable mail reveals what address was undeliverable.
The + and = are the default VERP delimiters. You can specify non-
default delimiters in main.cf with the default_verp_delimiters
configuration parameter (default value: +=). Specify two characters;
the first delimiter should match the $recipient_delimiter setting.
Using VERP with majordomo etc. mailing lists
============================================
In order to make VERP useful with majordomo etc. mailing lists,
you would configure the list manager to submit mail as:
sendmail -V -f owner-listname other-arguments...
This text assumes that you have set up an owner-listname alias that
routes undeliverable mail to a real person:
/etc/aliases:
owner-listname: yourname+listname
In order to process bounces we are going to make extensive use of
address extension tricks.
You need to tell Postfix that + is the separator between an address
and its optional address extension, that address extensions are
appended to .forward file names, and that address extensions are
to be discarded when doing alias expansions:
/etc/postfix/main.cf:
recipient_delimiter = +
forward_path = $home/.forward${recipient_delimiter}${extension},$home/.forward
propagate_unmatched_extensions = canonical, virtual
(the last two parameter settings are default settings).
You need to set up a file named .forward+listname with the commands
that process all the mail that is sent to the owner-listname address:
~/.forward+listname:
"|/some/where/command ..."
With this set up, undeliverable mail for user@domain will be returned
to the following address:
owner-listname+user=domain@your.domain
which is processed by the command in your .forward+listname file.
It is left as an exercise for the reader to parse the To: header
line and to pull out the user=domain part from the recipient address.
VERP support in the Postfix SMTP server
=======================================
The Postfix SMTP server has a new command XVERP to enable VERP
style delivery. The syntax allows two forms:
MAIL FROM:<sender@domain> XVERP
MAIL FROM:<sender@domain> XVERP=xy
where x and y are the VERP delimiters. When no VERP delimiters
are specified, Postfix uses the two characters specified with the
default_verp_delimiters configuration parameter.
VERP support in the Postfix sendmail command
============================================
The Postfix sendmail command has a -V flag to request VERP style
delivery. It is not possible to override the default VERP delimiters.
VERP support in the Postfix QMQP server
=======================================
When the Postfix QMQP server receives mail with a an envelope sender
address of the form:
prefix-@origin-@[]
Postfix generates VERP sender addresses using prefix@domain as the
original sender address, and using "-=" as the VERP delimiters.

/* NAME
/* bounce_notify_verp 3
/* SUMMARY
/* send non-delivery report to sender, server side
/* SYNOPSIS
/* #include "bounce_service.h"
/*
/* int bounce_notify_verp(service, queue_name, queue_id, sender,
/* verp_delims, flush)
/* char *queue_name;
/* char *queue_id;
/* char *sender;
/* char *verp_delims;
/* int flush;
/* DESCRIPTION
/* This module implements the server side of the bounce_notify()
/* (send bounce message) request. If flush is zero, the logfile
/* is not removed, and a warning is sent instead of a bounce.
/* The bounce recipient address is encoded in VERP format.
/* This routine must be used for single bounces only.
/*
/* When a message bounces, a full copy is sent to the originator,
/* and an optional copy of the diagnostics with message headers is
/* sent to the postmaster. The result is non-zero when the operation
/* should be tried again.
/*
/* When a bounce is sent, the sender address is the empty
/* address.
/* DIAGNOSTICS
/* Fatal error: error opening existing file. Warnings: corrupt
/* message file. A corrupt message is saved to the "corrupt"
/* queue for further inspection.
/* SEE ALSO
/* bounce(3) basic bounce service client interface
