Postforward is a mail forwarding utility which aims to complement
|
|
the Postfix Sender Rewriting Scheme daemon (PostSRSd).
|
|
|
|
The downside of using PostSRSd from postfix config is that all mail
|
|
is naively rewritten, even when no forwarding is actually performed.
|
|
Such rewritten Return-Path addresses may confuse sieve scripts and
|
|
other mail filtering software.
|
|
|
|
This is where Postforward comes in. Instead of rewriting all incoming
|
|
mail regardless of final destination, mail systems may be configured
|
|
to pipe mail into Postforward only when forwarding needs to happen,
|
|
e.g. in a users' .forward when the forwarded-to mailserver requires
|
|
it, leaving non-forwarded mail unaltered by PostSRSd.
|
|
Postforward will rewrite envelope addresses for piped mail using
|
|
PostSRSd itself and re-inject these messages back into the queue,
|
|
destined for the forwarding recipient(s).
