You can approach 100% accuracy to block spam by picking a very high threshold, like 10 or 12 points. I think it's pretty safe to block at those levels (best to 550 reject via some sort of milter). For lower scores (between 5 and 10), just tag with a Subject header and leave the filtering decision up to users. Instead of doing: > 5 ... tag > 10 ... block You can also do something like: > 5 ... tag > 8 ... tag and folder into a "spam" folder Or some mix. As far as rule sets goes, the URL module is the best rule set you can use. Start with that and other baseline rules and see where that gets you.
