sorry, I must be missing something. Why would postfix be talking directly
to dovecot? Or play middleman between some external entity and dovecot? Or
did you mean something else?
Postfix (which is likely to be your SMTP server) uses (very often) Dovecot
for the SASL authentication.
The communication between Postfix and Dovecot is usually via a Unix socket and
not IMAP, which explains why it was (always) working even if IMAP wasn't
working.
Check postconf -n and you will likely have something like
..
smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth
..
I'd advise you to put the server offline (or firewalled appropriately) until you
have everything set up, to avoid making things worse.
Good luck!
Bernardo
Thanks

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
I'd guess it's coming via postfix.
Aki
