SPAMfighter Exchange module (SEM), is the easy-to-use anti-spam/ antivirus solution for Microsoft Exchange Server 2000/2003/2007/2010/2013 or Microsoft Small Business server. SEM is powered by the SPAMfighter Server, which is updated by the SPAMfighter community of more than 8 million dedicated spam fighters across the globe. SEM delivers fast spam protection with no configuration or maintenance. SEM integrates effortless with Microsoft Exchange Server 2000, 2003, 2007, 2010, 2013, making the solution very fast and easy to use. 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 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 users. This makes for a solution that is both user-friendly and secure.
