Hi,
I'm looking for a suggestion on the best setup for sending an a u t o
r e s p o n s e with a c h a n g e o f a d d r e s s notice,
with a Postfix/Dovecot mail server, while still forwarding the message.
Option 1: virtualmail...@olddomain.tld -> alias ->
unixacco...@newdomain.tld (this account has auto response enabled)
Alternatively, this could use two virtual mailboxes, however I can’t
seem to configure Sieve to work without Dovecot handling the message.
Option 2: virtualmail...@olddomain.tld —> alias ->
virtualmail...@newdomain.tld (this account has auto response enabled)
The existing configuration uses Postfix virtual_mailbox_domains to
receive mail from both domains (old and new accounts). Two new,
replacement, recipients are UNIX accounts. Mail is redirected using
virtual_mailbox_maps to rewrite recipient addresses to the new address.
Since this happens before delivery, it is not possible to set an auto
response (e.g. a vacation message) strictly for the old addresses
because .forward + vacation work at time of final delivery, and possibly
not at all for virtual mailboxes.
I did get fairly far with the Pigeonhole project and Sieve, but
eventually discovered that it will not work for aliases, and, if I
removed the mail forwarding and just used a virtual mailbox (see error),
sieve does not process because postfix delivers the message without
Dovecot.
Error:
Jan 9 00:46:42 inet dovecot: lda(user)<11193><VvDSMCqpFl65KwAA+arxkQ>:
sieve:
msgid=<CAKge6ZKYBux=7nrwuvupycpuxs_t5gxznuflvsqsu8a3c5a...@mail.gmail.com>:
discarding vacation response for implicitly delivered message; no known
(envelope) recipient address found in message headers
(recipient=user@localhost, and additional `:addresses' are specified)
It would seem this has to be done with before-queue content filtering,
however the principles of operation do not include auto responses (and
with mail looping risks, this is understandable).
In general terms, I would imaging having a fairly straightforward method
of accomplishing this would be very useful for all the organizations
that go through names changes, merges, etc.
Thanks for any suggestions!
Robert
