Got it.
Before I follow up with a few questions, I was reading MS wiki and 
specifically in regards to using the bayes filter with SQL. Has anyone 
tried that? Pretty good? It looks fairly simple to setup. If its worth 
it, I may look at that and implement it.

Alright. Disabled 'bayes_auto_expire' in local.cf.

Setup Mailscanner.conf as suggested.

Rebuild Bayes Every = 43200


On the second part, just so im clear, something like this would suffice?

sa-larn --force expire /path/to/bayes
or
sa-learn --force expire /path/to/spam.assassin.prefs.conf

Could I run the force expire right now? Network traffic is fairly light 
right now. I'd like to give it a go.

Thanks,

Jason
