Spamihilator

Spamihilator is a full featured anti-spam filtering program that works with any email client. It runs as a local POP server that sits between your email program and your mail server and filters mail based on a built-in filtering mechanism. In addition, you can maintain a blocklist as well as a list of friends (their mail will never be filtered) and customize the filtering with a variety of settings and plug-ins. The program automatically configures popular email clients (Outlook, Outlook Express, Netscape etc.) to work with the filter. Among many other options, you can change the aggressiveness of the filter, block certain attachment types, block specific senders and also add your own spam words to look for. Spamihilator does not delete the spam right away but moves it to a recycle bin from where you can review it, restore items or permanently delete them. A very flexible and capable spam filtering system.
