I'd check your postfix main.cf config for something obvious. My hunch is that the dovecot process is handing off the reply message to your MTA with the correct from address (I'm actually using /usr/sbin/sendmail for outbound mails/replies) and the MTA is rewriting the from address.

Hello everyone.
I'm running dovecot (1.2.9) with postfix (2.7.0) on an ubuntu 10.04.1. I'm hosting mail for several domains and using the dovecot local delivery agent. Everything has been working great.
However, today I set up a sieve script to send out-of-office replies (vacation) for one of our users. I tested it and got the response just fine. However, when looking at the "From" header of the auto-reply, I noticed that the domain name was wrong.
My postfix master.cf line for doing local delivery is:
dovecot unix - n n - - pipe flags=DRhu user=mail:mail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${nexthop}
My LDA configuration is:
protocol lda { postmaster_address = postmaster@our-primary-domain.com hostname = our-primary-domain.com mail_plugins = sieve quota_full_tempfail = yes deliver_log_format = msgid=%m: %$ rejection_reason = Your message to <%t> was automatically rejected:%n%r }
So, our main "administrative" domain is: my-primary-domain.com, the mail server being mail.my-primary-domain.com. I sent an email to a user: janedoe@my-other-domain.com and the LDA with Sieve successfully sent me a reply. However, the "From" was: janedoe@mail instead of janedoe@my-other-domain.
According to: http://wiki.dovecot.org/LDA/Sieve#Vacation_auto-reply
Vacation uses envelope sender and envelope recipient ... taken from: ... V 1.1+ ... Envelope recipient: -a parameter to deliver if given, otherwise -d parameter to deliver. If neither is given (delivering to system users), the $USER environment is used.
Just for kicks I tried changing my master.cf to use -a instead of -d but then all mail delivers to user "mail" completely breaking all mail delivery. Anyhow, vacation auto-responders are fundamental to operations here and we manage mail for several separate companies. We need the "From" address to reflect the domain of the actual company. I'm stumped as to why sieve isn't getting/using the envelope sender's domain. I'm hoping someone here can point out (a hopefully obvious) mistake.
I've attached my four pertinent config files as etc.tgz only slightly scrubbed.
Any help is greatly appreciated.
