Improve employee productivity, reduce liability and reduce mail server load by filtering unsolicited and inappropriate email before it enters your network. Spam is detected through a combination of heuristic analysis, word matching, white and black lists, server authentication, address verification and fingerprint checks.  Spam has grown into a major problem for all companies and organizations. Spam is especially problematic for public email addresses (listed on a website, for instance), or for common email addresses (support@company.com). Spam is also the primary delivery mechanism for Phishing attacks, so it now has security implications.

Anti-Spam solutions should automatically reject, quarantine, redirect or tag and deliver filtered e-mails based on configurable thresholds.  To prevent unintended filtering, Spam filters generally allow you to create your own "white lists" of trusted senders, such as customers and business partners. Business level Anti-Spam solutions should also accommodate different business needs and risk tolerances by allowing adjustments to spam detection rules, thresholds and actions. 

Some of the latest spam fighting technologies, include Bayesian Filtering, Historical Averaging, enhanced Heuristic Analysis, and Sender Policy Framework (SPF) technology.  These new technologies automatically learn to differentiate unwanted messages from legitimate email.  With user controlled teaching tools, such as an Outlook email plug-in, you can train Anti-Spam solutions to get better at catching spam with very little required by IT managers.
