This is quite a decent anti-spam platform. It does however taque some finnesse in configuring it. The interface is clean and functional but can be a little confusing until you guet used to using it. I have not experienced many crashes. And of coarse its open source and free and it worcs so theres three positives.

Excellent resuls if configured correctly.
