SpamAssassin – A major new release!
“SpamAssassin is, by any measure, the most popular open source spam filtering software. It has won numerous awards, and has been incorporated into many commercial filtering appliances. On Tuesday, the SpamAssassin developers announced version 3.3.0, their first major update since 2007.
In general, any message with a SpamAssassin score of 5 or more is considered to be spam. It’s very rare for a single test to contribute enough to the score to be definitively spam or definitively not spam; instead, the effects of multiple tests are cumulative.” – via @returnpath
