Its easy and it gets most of the Spam. I have to browse the spam because it sometimes sees a false positive, but once I OK an e-mail address it's never challenged again.

One good thing about it is that it looks at all the other people's designated spam and if an address exceeds a threshold it stops it from you as well, without asking.

It checks all incoming e-mail and routes suspected spam to a spam folder. The real prize is its automatic update feature, which keeps its spam lists current - like a virus checker.
