New install of ver. 2.0.3.2 (upgrade from ver 2 failed), trained with 2500 SPAM and 3000 HAM recent messages from this domain.

I have found that even with RBL checking on (orbs disabled per NoSpamToday default settings) I need to set the Reject & Redirect threshold to 3.0 in order to get the most effective blocking.

With the default being 5.0 considered "very aggressive" and posts I've seen recommending 5.7, I'm wondering whether with the Bayes auto learning turned on that I'll have to increase the threshold over time.

I've trained the Bayes database with 2500 SPAM and 3500 HAM messages.

I'm currently monitoring the redirect mailbox for false positives, and over three days have found none (extensive use of Whitelist feature).

Thanks for any input.

I think it also depends on how many (additional) filter sets you use...
