Ok, we have this setup now
Internet ---> Filtering server (Running postfix/spamassasin/uvscan/anomy) ---> Courier mailserver
Is there a way to setup the courier server so it only accepts mail coming from the filtering server, also this must be done on a domain level, not all domains have their mail filtered.
You can control where mail goes for a given domain by setting up your DNS MX records correctly.
If the Mydoom worm is doing that, then simply rename mail.domain.com to jsadhfjh.domain.com, and make the appropriate configuration changes. Problem solved.
not if i got 1500 users who access the server via mail.domain.com ...
