Is there any bayes scores in the headers of the messages?
Are you running any extra rules from
Are you properly set up to not accept mail to non-existent addresses?
Does your exchange server have a non-public address that can only be reached 
by the mailscanner box? Otherwise the spammers will find it.

MailScanner is like deodorant...
You hope everybody uses it, and
you notice quickly if they don't!!!!
