Spam is a problem for everyone nowadays. If you run a Microsoft Exchange server, finding a cheap spam filtering solution is not easy. Most commercial programs want to charge you by the mailbox and most open-source solutions are meant for Unix like systems.

Open Relay Filter Enterprise Edition by vamsoft ( http://www.vamsoft.com/ ) costs $200 per server and provides a very comprehensive list of anti-spam features. It offers greylisting, Active Directory integration, SURBL support, and much more. It even will work with open-source software like ClamAV and SpamAssassin. Vamsoft offers a 30 trial version, too. If you run a Microsoft Exchange server, it is certainly worth a look.
