Spam filtering stopped working

[Laszlo Nagy]

Hi All,

I upgraded my BSD system recently. Portupgrade also upgraded MailScanner 
and berkley db. For some reason, the new Mailscanner is not doing spam 
filtering. Everything else is working - bad filenames detected, virus 
scanner works. The MailScanner configuration file was not changed since 
last rebuild. The maillog contains no error messages. When starting up 
MailScanner, I see no error messages.

How can I find what the problem is? Where should I start?

Thank you,

   Laszlo
