Products Overview   SpamRepellent   OEM SDK Solutions   Products Brochure (.pdf)   Products Overview Mail-Filters uses a different technology from 98% of other spam filters on the market - for one very good reason - we believe our customers cannot accept false positives.  False positives (i.e. the marking of good mail as spam) can lead to more damage than the spam created in the first place (can you imagine missing a customer email because your filter quarantined or deleted it?).  As a result, we've crafted our filters to be the most accurate with false positive rates of less than 1 in 1,000,000 messages while still catching over 95% of the spam. The Technology Spam is subjected to two proprietary anti-spam weapons: The Mail-Filters STAR Engine detects spammer tricks, allowing it to catch new types of spam, like embedded content, HTML and foreign language spam. Mail-Filters Bullet Signatures are small, targeted, and lethal spam signatures handcrafted by human editors. Bullets are not checksums or hash values based on the whole message or single key words, which are easily defeated by today's spammers. Instead, Bullets are based on a combination of attributes of the message that are unique to that spammer (to eliminate false positives), and repeatable from one spam message to the next. Bullets are most often crafted from information in the body of the message, but can also be developed using the subject or other header information. The Bullet Database is constantly updated, as often as once per minute, to insure effectiveness and accuracy.
