Thomas,
If I understand what you're saying, you want to prevent spammers from circumventing your filtering server, correct?
bingo!
What's happening is spam is still getting by the filter because they connect
directly to your mail server and not to the filter?
right, most recently the Mydoom worm ...
It would be best if you configure a firewall in front of your mail server to
allow incoming pop/imap traffic and deny traffic for incoming SMTP. Route all
mail through your filter, but turn off the filter for those domains that don't
want filtering. Your filter should allow that - if not, you don't have much of
a choice. You will probably need to move those domains to another machine.
Then the firewall would be responsible for only allowing SMTP connections from the filtering server to the "real" mailserver behind the firewall ?
