SpamButcher is an advanced anti-spam filter. Its spam blocker can stop 98% of spam. Every few minutes the anti-spam software checks for new messages in your inbox. If it finds any unwanted email, it's moved to a holding area for your later examination. It exhaustively examines the text of each message, where it originated from and other information within the email. SpamButcher even takes into account common tricks used by spammers to sneak past other spam filtering systems. SpamButcher's email filter uses a fuzzy logic expert system to determine which messages are spam, and which aren't. SpamButcher can optionally send you scheduled reports of blocked spam via email. With supported email clients, inadvertently filtered messages can be restored directly from the reports. SpamButcher will work as a spam stopper for Windows users whose mail accounts are accessible via the POP3 protocol. This includes most non-web-based mail accounts. SpamButcher does not work with AOL or Hotmail accounts.

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.
