Alligate is a high performance anti-spam gateway server for Windows.

There are dozens of popular Anti-Spam products available that do a decent job of integrating with your email server and blocking spam. Unfortunately, most of them are designed to work with a specific email server platform and can seriously stress your mail server software and hardware.

Alligate is different. It works with any mail server on any operating system, and requires no special hardware or additional software. It allows you to continue to use your existing Anti-Spam configuration without modification while reducing the load on your current setup by at least 90%. You can add years to the serviceable life of your server.
