SpamAssassin 3.0 is out! Notable in this release is the inclusion of a check against the Spam URI realtime blocklists (a huge help in the fight against spam), use of Sender Policy Framework tests (a huge help in the fight against fraudulent return address information), better integration with databases for storage of preferences and filter information, and a move into the Apache Software Foundation. If you run a mail server, you’d be doing yourself and your users a favor by hopping over and grabbing it.
