This project provides a antispam daemon to detect and greylist or reject spam in your MTA by analyzing the smtp envelope using different rules.
At the moment Postfix and Exim are supported. The daemon runs on Windows (using .Net 3.5) as well as on Linux (using Mono 2)
The library is released under Apache License 2.0
Feel free to use the daemon. If you use it, I would be nice, if you send me your feedback and link to this page.
Amazon.de gift cars are welcome. ;-)
