Hello all,
Not sure if this is the place to ask this, just trying to track it
down. I'm running Cyrus 2.2.12 with Postfix 2.2.2 for only 45 users.
Every once in a while, but much more recently, users are receiving
emails sent a few days ago - again. The recent repeat emails were all
from users on our network sent to all users on our network. The
headers appear like regular, legit emails. Any thoughts as to what
could be going on or where to begin looking.
Any input is greatly appreciated. Thanks.
We saw a situation like this some years back, which was caused by
misconfiguration between postfix and cyrus. The specific problem we saw
was that when a local user sent a message to a group of local users, and
one member of the group (mailing list, alias expansion or whatever)
generated a 4XX (temp fail) error on delivery, then we would see the
whole list get the message again when the cause of the temp fail was
cleared up (such as quota getting fixed).
I don't remember the exact fix, but it involved switching from
mailbox_transport to local_transport in postfix, and switching from
alias_maps to virtual_alias_maps as well. This causes the redelivery
attempts to occur post-alias expansion rather than pre-alias expansion.
I know this is off topic for the cyrus-imapd list, but thought others
may find it helpful.
Cheers,
-nic
