Freeware In Anti-Spam

With xTerminator you can check e-mail while its still on server, automatically filter unwanted messages, manually check messages before deletion (optionally), save bandwidth, lessen the chance of virus infection, Clean multiple accounts, create custom filters, block all but friendly messages (optional), auto-reply with pre-defined message.

Built-in Challenge/Response System allows you to send people a question (like, whats my pets name?) that, if correctly answered, will provide them with a password so their messages will not be deleted again or even automaticall added to your "Friendly Content" list.

The new Learning Filter (Bayesian Filter) uses the rules of Thomas Bayes (English mathematician, 18th century) and calculates a certain Spam-Probability for every E-Mail. You can train this filter! So it will know your messages even better than you. Hence the recognition rate will continuously increase.

In addition Spamihilator uses a Word-Filter, that searches messages for known keywords.

Of course, Spamihilator supports Plugins. These useful additional filters protect your system against annoying spam mails.
