Thanks for the clarification. In the postfix log, it states the following reason for rejection: Mar 3 08:34:34 mail postfix/smtpd[28049]: NOQUEUE: reject: RCPT from unknown[10.0.0.2]: 550 5.1.1 : Recipient address rejected: User unknown; from=<> to= proto=ESMTP helo= So it seems that the RCPT TO is rejected because the server (relay) doesn't accept the SRS adress as recipient. Is there any way to manipulate the RCPT TO from pigeonhole to match the To header? Seems like I have to look into postfix if there is a way to decode the RCTP TO. Unfortunately, I am still not too knowledgeable about SRS, but will try to find out more. Best regards, Matthias -- Matthias Petermann

Hello,
we face an issue with the vacation extension of pigeonhole. Our
upstream mail server (from which we pull our E-Mails with POP3) uses
SPF and performs a SRS re-write of the Return Path. Once the mail is
processed via our local postfix, it is delivered via dovecot deliver
(using the lda). When the recipient has a vacation rule enabled in
sieve, the out-of-office note cannot be sent, as pigeonhole tries to
use the Return-Path (which is not accepted as sender by the mail server).
We are using the following dovecot / pigeonhole versions:
dovecot-2.3.2.1
dovecot-pigeonhole-0.5.2
As of my understanding, the problem was addressed in pigeonhole
version v0.4.21 by introducing the
sieve_vacation_to_header_ignore_envelope setting. Anyway - even when
this is set to "yes" pigeonhole still uses the Return-Path instead of
the "From:" header which I had expected:
Feb 27 13:22:26 mail dovecot:
lda(customer)<48383><3o+yOQGBdlz/vAAAZU03Dg>: Error: sieve:
msgid=: failed
to send vacation response to
SRS0=gwGXg6ad=RC=petermann-it.de=matth...@example.com: program returned error> (temporary error)
Are my expectations wrong or did I miss some precondition?
That setting is only about the composition of the "To:" header for the
outgoing vacation message (it's in the name). It has nothing to do with
the RCPT TO envelope address used for that message. Why exactly do the
mail servers reject the vacation message (I am not too familiar with SRS).

Stephan.
