Anti-Spam Filter

Anti-Spam Filter is an innovative self-learning system, offering you spam protection without deleting the important correspondence. Anti-Spam Filter maintains its own collaborative spam-tracking database, which uses the signatures of spam messages. It is different from other anti-spam programs, in the way that you're not the only one to "teach" it, but all of our project users contribute to it. Upon studying many spam-detection algorithms, we have come to a conclusion that only a human being is truly a hundred percent capable of telling spam from regular messages. Even the most complex algorithms can make mistakes, and can either pass the spam through or, much worse, delete an important letter. The only way of generating a real spam killer is uniting all of our efforts. Aside from initial spam filters, provided by our program and created by our developers, Anti-Spam Filter presents a claim submission practice, in case you have got some spam coming through. The process is ultimately simplified - to report spam you just have to make two mouse-clicks. Anti-Spam Filter features: 1. 100% guarantee that an important letter will never be deleted 2. A regularly updated collaborative spam-tracking database 3. Spam- and virus-containing emails eliminated 4. Foreign spam blocked 5. Multiple email accounts protection 6. Any POP3 compliant email program supported
