The SpamButcher Spam Blocker Utility

SpamButcher was the first commercially released spam filter to use fuzzy logic to distinguish spam from legitimate email. After several years research and development, this system has been tuned so that it can eliminate over 97% of spam, with a lower risk of false positives than other spam utilities.

Amongst other features, the application includes user-definable blacklist and whitelist entries, user-created filters and DNS blocklist (DNSBL) support. SpamButcher can provide filtering for up to 9 different email accounts.

Since it operates as a stand-alone spam utility application, it doesn't tie you down to a single email client. You can benefit from a spam-free inbox even if you're checking email via your PDA or cell-phone.

Some spam blocker utilities need regular 'profile' updates in order to maintain their ability to stop unwanted email. Some even charge you to keep the application up to date. SpamButcher is a single purchase. After buying, future updates and support for SpamButcher are free of charge.

SpamButcher's licensing even allows you to use it on one additional system (with the same primary user) without extra cost.
