First major release for SpamAssassin since 2007.

This latest version changes how SA rules are updated. Rules in 3.3.0 are now separated from the core product and are updated using sa-update. We have always recommended using this technique, and users who have the ConfigServer MailScanner Front End set up on their server are using this method with 3.2.x versions of SA.

SA users wishing to upgrade should absolutely read the Apache ugrade notes:

http://svn.apache.org/repos/asf/spamassassin/branches/3.3/UPGRADE

Some highlights:
- The DKIM plugin is now enabled by default if perl module Mail::DKIM is installed.
- Many core functions are now moved to plug-ins.
- DCC and Razor now disabled by default (licensing issues).
- Some Bayes options moved to plug-ins.
- Support for multiple "init" files in SA directory.
- NO RULES ARE INCLUDED OUT OF BOX NOW! sa-update handles rules.
