Postforward is a mail forwarding utility which aims to compliment the
Postfix Sender Rewriting Scheme daemon (mail/postsrsd).
The downside of using PostSRSd 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,
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).
