Now the question is, OK, that attempt may be some attacker trying to get in, this happens but... HOW is he succeeding to TRY to connect, if dovecot doesn't appear to be listening at all??? And of course, does this help in any way to figure out what is wrong with my configuration?

Thanks, Marco

Try adding

protocols = imap

Hi Aki,

adding this right before the service imap-login part of dovecot.conf worked, thanks!

Now, what about that authorization attempt? What happened, why, how... and is that as sign of some weakness in the system, and how should I fix it?

Thanks, Marco
