SpamAssassin update

I made a few updates to SpamAssassin this morning. First I upgraded from version 2.61 to 2.63 which included a few bug fixes and some minor changes to the rules. Second, I enabled real time block list and DCC checking. That means SpamAssassin will query servers on the net to see if email matches a signature of known spam. This should give us even more reliable spam detection. The only down side is that it adds a few more seconds on to the time it takes to deliver an email and uses a small ammount of internet bandwith. Hopefully that is not noticeable. However if anyone discoveres any problems with these chagnes, please let me know so I can roll them back.
