When I did spamassassin I relied on the content scores and bayesian database and it worked quite well after I culled a huge amount of example junk email and good email and fed it into the bayesian database (1000s of emails).

I have since bought Ironports as our needs grew. These use a shared reputation database between all Ironport customers that every appliance sends updates to and receives updates from based on "outbreak filters", which I suppose work like spamassassin's content scoring.

It would be nice if there was a shared bayesian database between all spamassassin users.
