Spam Filtering

SpamAssassin is an intelligent email spam filter

All webhosting accounts with New Winnipeg Media include free spam filtering thanks to Spam Assassin.

SpamAssassin's practical multi-technique approach, modularity, and extensibility continue to give it an advantage over other anti-spam systems. Due to these advantages, SpamAssassin is widely used in all aspects of email management, filtering incoming as well as outgoing email.

SpamAssassin uses a wide variety of local and network tests to identify spam signatures. This makes it harder for spammers to identify one aspect which they can craft their messages to work around.

SpamAssassin's primary features are:

Header & body phrase tests

Bayesian filtering

Automatic address whitelist/blacklist

Manual address whitelist/blacklist

Collaborative spam identification databases (like Razor)

RBL (Realtime Blackhole Lists)

DNS Blocklists
