BitDefender Antispam:
How about just reading your mail, for a change?
Spam is a growing problem, both for individuals and for organizations. It comes in a wide range of shapes and sizes, and theres a lot of it.
BitDefender AntiSpam 7 incorporates three different proprietary modules to keep your personal inbox spam-free:
Heuristic filter
The heuristic filter performs set of tests on all the message components, (i.e. not only the header but also the message body in either HTML or text format), looking for words, phrases, links or other characteristics of spam.
Bayesian filter
The Bayesian filter module classifies messages according to statistical information regarding the rate at which specific words appear in messages classified spam as compared to those declared non-spam (by the admin or by the heuristic filter).
White list/Blacklist
Crude, but effective. Know your friends, know your enemies. Thats all there is to it.
These techniques are used in conjunction by the BitDefender AntiSpam filter, to determine whether a certain piece of mail should make it to your inbox or not.
