Im running a good combination of Spam Assassin, ClamAV and the DNSBL. SpamAssassin does a very good job filtering great deal of the spam messages that are currently know. ClamAV eliminates potentially risky attachments in an efficient way without adding more that 5 or 6 seconds delay to the delivery of the Email. And finally for DNS blocking I use three services that block know spammers IP, they are zen.spamhaus.org dnsbl.sorbs.net bl.spamcop.net This 3 services do an IP lookup of the originating IP and determine if they are know spamming address and in that case drop the connection inmediatly, elmininating this way more that 60% of the spam traffic to my site. BTW I use sendmail, but I think every other MTA should be able to configure this DNSBL. Hope these helps you. And very important if you are in a low budget since everything I use in here is open source and free services. Ing.
