SPAMfighter Exchange module (SEM), is an anti-spam/virus product for Microsoft Exchange Server 2000/2003/2007 or Microsoft Small Business server. SEM is powered by the vendor's SPAMfighter Server, which they state is updated by the SPAMfighter community of more than 5 million users across the globe.

SEM delivers spam protection with, according to the vendor, no configuration or maintenance. It integrates with Microsoft Exchange Server 2000, 2003 and 2007. As E-mail 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, which is integrated with SEM and managed via the same interface.
