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=<e081d2ba-21d5-c32b-3750-69fe0c8a76d2@petermann-it.de>: failed to send vacation response to SRS0=gwGXg6ad=RC=petermann-it.de=matthias@example.com: <Sendmail program returned error> (temporary error)
Are my expectations wrong or did I miss some precondition?
Best regards, Matthias
