[Dovecot] Sieve Vacation for redirected email
I posted this elsewhere, but under an old post. I apologize for the repeated question.
Hello Dovecot Users,
Dovecot 2.1.7
Our emails are redirected from the home office causing all vacation
responses to fail with, "discarding vacation response for implicitly
delivered message; no known (envelope) recipient address found in
message headers".
I need to use the Sieve Vacation option but cannot figure out how to
get it working for us. If I send to the local address, it works fine.
If I send to the redirect address, it fails with above error.
Unfortunately, all of our emails are redirects from a single domain.
There's got to be some way to make it work.
Any help would be greatly appreciated,
Dave

Postfix and dovecot handle everything nicely, but the vacation piece reports no known recipient, or if I add my address, it reports that can't send to itself.

Something's screwed up somewhere with your delivery. That Return-Path is wrong: it should be <friends@sender.com>. Vacation will only reply to the Return-Path address, so if that's wrong then the replies will never go to the right place (and, in this case, they'll never be sent since the Return-Path is your address).
Note that this would also apply to a bounce: if a message bounced because you were over quota, that bounce would loop and get thrown away and you'd never see it.
If your forwarder is rewriting MAIL FROM to work around SPF breakage, you need to switch to using SRS or something equivalent to get vacation to work.

From: Dave Gattis <friends@sender.com> To: SUMACO Gattis Dave <dave.gattis@domain-a.com>
You have two problems:
a) "no known (envelope) recipient address found in message headers" means, that the vacation :addresses list does not contain
dave.gattis@domain-a.com
because vacation probes the entries of the :addresses list against To and CC.
b) the messages are _resend_ not forwarded by spamcop.main.ch to your MTA. By doing so the original *envelope* sender address is lost, which is *not* the entry in "From:". Therefore vacation would send the reply to:
dave.gattis@domain-a.com
which is the return path per your excerpt. You could verify that by finding the envelope sender in the postfix logs, I guess; or by fixing a).
Actually, I'm not sure if pigeonhole can pick up the address to reply to from a mail header - I do not see any hints in the sample config. So, maybe, you need to ask spamcop.main.ch to preserve the return address.
Note: Changing the envelope sender is not bad by itself, it solves several problems with forwarding; a well-known MTA can do this, too: http://social.technet.microsoft.com/Forums/en-US/exchange2010/thread/8006eab... , but you get other problems rewriting the sender address.
