ok these go in to dovecot config file
switch various debug = yes
also make sure debug log path = syslog so everything goes to the system logger
also best to try with ssl enabled first as that can cause complications until you are up and running.

Looks like the logs are missing all the useful things that would've hopefully come after this. The error is coming from lmtp, not auth.
How can I ask Dovecot to produce more logs concerning lmtp?
From the postfix side I just have: "lost connection with pc-serveur.my_domain.org[private/dovecot-lmtp] while receiving the initial server greeting" I'd like to know why...
