SPAMfighter Exchange Module   
http://www.spamfighter.com

SPAMfighter Exchange module (SEM), is the easy-to-use anti-spam/virus solution for Microsoft Exchange Server 2000 and 2003. SEM is powered by the SPAMfighter Server, which is updated by the SPAMfighter community of more than 1 million users across the globe. SEM delivers instant spam protection with no configuration or maintenance what so ever. SEM seamlessly integrates with Microsoft Exchange Server 2000 and 2003, making the solution very fast. As email arrives and the Exchange Server routes it to its addressees, SEM constructs a unique signature for each message and sends it to the SPAMfighter Server for evaluation. If the SPAMfighter Server determines that a message is spam, it notifies SEM and the spam mail is moved to the user's spam folder. A version of SEM is also available with a built-in VIRUSfighter. This means that viruses, worms, etc., are removed before they can impact on users. VIRUSfighter is 100 % integrated with SEM, and is managed via the same interface. This makes for a solution that is both user-friendly and secure.
