Thank you for your reply. I still have a fair amount of spam going to unsure, .ome going to ham and some ham listed as unsure.
I have set my Pegasus filters to move unsure into the unsure folder. By doing this, I see a very minimum of spam get through to my "new Mail" folder. I train on the unsure to classify spam as spam yet sometimes ham gets wrongly assigned as unsure or spam. I look forward to those rare misclassifications of ham because they mitigate the ratio of unsure spam & ham listed as spam (which are always retrained). I suppose what I need to know is if there's an imbalance between the spam/ham ratio, does that affect the accuracy of Spambayes? After all is said & done, more spam than ham needs to be corrected and the ratio seems destined to be skewered to the left.
