Hello everyone,
I have following configurations (and more) at /etc/dovecot/local.conf in a
"/VirtualUserFlatFilesPostfix/" setup :
[partial file content begins]
[snip]
When incoming mail goes to a mailbox that does not exist, an error is logged
by Dovecot, letter remains at Postfix queue, and no rejection message to
sender (here host is /mail.example.net/):
Wouldn't it make sense to prevent postfix from attempting to deliver (via LMTP)
messages addressed to invalid users?
i.e. using virtual_mailbox_maps and/or virtual_alias_maps, as needed.
[partial]$ cat /var/log/dovecot.log

^^^ weird message, but maybe it's dovecot's way of saying "file not found" :)
Good luck.
