Hi,
We have a filter located outside our organization for outgoing mail
which rewrites the Return-Path to their domain, in the form:
username=abc....@theirdomain.com. Once the filter processes the message,
it's forwarded to the destination where these headers are received:
Return-Path: username=abc....@theirdomain.com
From: Foo <usern...@abc.com>
This destination instance also has this configuration for Postfix:
sender_canonical_maps = regexp:/etc/postfix/sender_canonical_maps
sender_canonical_maps:
/^(.*)@abc.com$/ ${1}@xyz.com
What I want to achieve is rewriting sender address when it's received
from a specific domain (concretely, abc.com). As per the
sender_canonical_maps documentation: Optional address mapping lookup
tables for envelope and header sender addresses.
I know the Return-Path doesn't match the regexp, but I believe the From
header does. Why it's not rewritten to usern...@xyz.com? Am I missing
something?
FWIW, this is Postfix v. 2.9.6-1.
Thanks.
