SPAM FILTERING

MailWatch utilizes a layered architecture that combines Brightmail with over twenty filtering techniques to effectively and accurately identify and block spam. Some of the filters are reputation-based, examining the source of the email. Others sift through the message content, applying signatures or heuristics technology. New spam attacks are closely monitored and an average of 30,000 new policies are automatically updated by MailWatch every day. The result is a service that consistently catches over 97% of all spam, with only one “false positive” in one million messages – guaranteed.
