Ok, here are my first results. Unfortunately, Outlook/OE actually
doesn't work with dovecot 2.0. Here are the traffic logs in comparison
to doveot 1.2. Tell me, if you need more detailed traffic. Plain and
login mechanisms are enabled on both versions. Note that dovecot 2.0
complains about login command...

With TB 2.x/3, everything works fine.
