Hello!
Having a problem here and am unable to solve it on my own and even dr Google is unable to help.
We have domain A on cloud, from where mail gets forwarded to our local server to domain B. Forwarding is done in SPF-compliant way by using SRS (this part we have no control over). This SRS address ends up in Return-Path header, and sieve vacation replies to this address.
This is all absolutely correct, but also useless, as sending mail to SRS address leads nowhere.
I've tried to edit headers in sieve before passing control to vacation, but that does not work. I tried modifying Return-Path to the value of X-Original-Sender (both in user's sieve file and using scripts in "sieve_before" parameter). Mail gets delivered with changed headers, but vacation acts upon original headers.
Is there a workaround? MTA is postfix (3.1.15), dovecot is version 2.3.4.1 (f79e8e7e4), Pigeonhole version 0.5.4 LMTP as local delivery agent.

That's a broken SRS setup then, if it doesn't handle responses to the sender address there will be some lost mail. Vacation and similar auto responses are _required_ to reply to the SMTP sender address.
