I never experienced this problem again (and it was quite frequent). As I
posted here http://www.dovecot.org/list/dovecot/2006-April/012953.html
the problem occurred as a result of my control panel (DirectAdmin)
starting Dovecot while it was already running (I'm not quite sure of
what happened when the control panel issued the command to start
Dovecot, but that was when Dovecot stopped responding). Since I disabled
the control panel's monitoring feature, Dovecot has been working
flawlessly.

No, there was no sign of any error.

There were no replies, the connection would just timeout.

This happened with POP3, don't know if it happened also with IMAP.

passwd-file

No, I didn't try that.


Thanks!
