weird postfix sasl problem with Outlook

[DULMANDAKH Sukhbaatar]

Hello all.

I'm been using dapper on my mail server until the last weekend. During
last weekend I've upgraded my system to gutsy. After that SMTP
authentication for postfix is not working for Outlook. On thunderbird
and evolution I can send any mail using smtp authentication, but on
Outlook postfix saying "Relay access denied" or something like that.
In addition Outlook configuration worked fine with Dapper.

Here is little excerpt from main.cf:

smtpd_sasl_auth_enable=yes
broken_sasl_auth_clients = yes
smtpd_sasl_type=dovecot
smtpd_sasl_path=private/auth

After all I've no clue where the problem is, and how I can fix it. Did
I missed something? Any clues?
