Hi Timo!

I tried the patch with 2.0.19 and the dovecot error messages disappeared.

I still get a lot of this postfix warnings:

SASL LOGIN authentication failed: Connection lost to authentication server

but only for ips which tried a sasl brute force attack.

"Connection lost to authentication server" could this be because of
the dovecot auth penalties?
so far i did not get any complaints from users.

Thanks for your help!
