Hi Experts,
I got a zimbra e-mail server and I had this particular problem it took zimbra 5 days to notify the senders that the adress was invalid...

in zimbra.log after 40 hours :
Mar 13 07:56:35 mydomain postfix/smtp[15788]: 5A90834115: to=<jblow@invalidaddr.com>, relay=none, delay=147372, delays=147369/0.02/2.4/0, dsn=4.4.3, status=deferred (Host or domain name not found. Name service error for name=invalidaddr.com type=MX: Host not found, try again)

the senders should be notify immediately if the e-mail is invalid.
in this particular case the e-mail was sent march 11 and my user received the error march 16.

Thanks,

postconf -e maximal_queue_lifetime=3d
postfix reload
or
zmlocalconfig -e maximal_queue_lifetime=#d
zmmtactl restart

You can also tweak bounce_queue_lifetime (the mailer deamon messages themselves), queue_run_delay, minimal_backoff_time, maximal_backoff_time


Personally I still wouldn't set it for less than a day, since there's perfectly valid reasons such as temp errors or too many connections etc on the other end.
