Cactus Spam Filter is a spam blocker. It protects your inbox by learning to detect spam as it's being used.
After a short while it has adapted to your personal mailbox and blocks out most of the junk e-mail.
This spam stopper integrates seamlessly with all e-mail clients that use POP3 such as Microsoft Outlook, Microsoft Outlook Express, Netscape, Opera, Mozilla, Eudora, IncrediMail, Pegasus Mail, Foxmail, and Phoenix Mail.
After you have downloaded and installed it no more settings are required. No account setup and no POP proxies.
Just start your favorite e-mail program and Cactus Spam Filter will instantly protect it.
