Thomas, If I understand what you're saying, you want to prevent spammers from circumventing your filtering server, correct?
What's happening is spam is still getting by the filter because they connect directly to your mail server and not to the filter? Unfortunately, if you allow some access to SMTP on the mail server, then it will always be open for the internet to get around your filter - regardless of your MX records. If you have EXPN and/or VRFY turned on then spammers can easily interrogate your Courier mail system - which negates the whole reason for having a filtered server. 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. D -- Derrick T.
