I’ve found this website when tried searching spam killer in google.com last month and I’ve not much time to learn more about it. But I think it’s an interesting program to kill the spam mails!
Just take a look:
The Apache SpamAssassin Project
The Powerful #1 Open-Source Spam Filter
Free software: it is distributed under the same terms and conditions as other popular open-source software packages such as the Apache web server.
