Re: LDA-based vacation responses bouncing

Looks like my virtual_mailbox_domains setting in postfix was not doing
the proper lookup, so it thought my domain was local. I've fixed that,
so this is no longer an issue.

LDA-based vacation responses bouncing

[micah anderson via dovecot]

I've got dovecot vacataion auto-responses working via sieve, but when
the responses are sent, they are sent as if they are to be locally
delivered, which causes them to bounce for domains that I am not local
for. How can I get dovecot's sieve vacation response to check the domain
is local or not?

Here is an example of what happens:

The LDA notices it needs to send a vacation response:
2019-05-14T10:50:47.827466-07:00 brant dovecot: 
lda(u...@example.org)<14817>: sieve: 
msgid=<20190514135045.012486@localhost>: sent vacation response to 


but that response was sent via the postfix pipe through the dovecot lda
transport... because that is local, and the domain it is sending to is
not local, it bounces:

2019-05-14T10:50:47.92-07:00 brant postfix/pipe[14821]: C998381539: 
to=, relay=dovecot, delay=0.11, delays=0.04/0.01/0/0.06, 
dsn=5.1.1, status=bounced (user unknown)

Postfix is set to do this:

dovecot  unix-   n   n   -  -   pipe
  flags=DRhu user=mail argv=/usr/bin/spamc --connect-retries=1 -H -d 10.0.1.92 
-s 1024 -t 100 -u ${recipient} -e /usr/lib/dovecot/dovecot-lda -f ${sender} 
-d ${recipient}


require ["fileinto", "vacation"];
vacation
  :days 2
  :subject "Helllo"
"Hi";
