Hello Timo and Urban
I took quite a long time to reply, but as I told you this issue does
not verify very often, so I had enabled verbose logging and just
waited ..
Enabling mail_log plugin and/or lazy_expunge plugin would have helped more (both mentioned in my previous mail).
I summarize the situation - user mmanzoni sometimes does not receive a
message - it does not matter if he is the only recipient or if there
are othersits outlook 2010 is configured for POP3 mail and to leave all messages
on the server, and setup to never delete them (neither after a few
days, neither when he deletes from his trash folder). There are not
any other client that log to that mail account: this is the only one
client that download messagesthe following extract of the LDA log shows what happened: the message
was sent to 4 users (I report just 2 of them: criva, that received it,
and mmanzoni, who didn't)
There's really nothing in the LDA log that could explain why the message gets lost. It most likely was successfully delivered by LDA, but got deleted afterwards for some reason.
You mean that this user's mails are never supposed to be deleted via POP3? Verify that with:
grep 'pop3.*mmanzoni.*del=[^0]' /var/log/dovecot.log
or wherever those POP3 disconnection messages are logged, i.e. you should find lots of messages with:
grep 'pop3.*mmanzoni.*del=0' /var/log/dovecot.log
