No matter what I do I can't get Poco's Bayesian Filters to give the same performance in blocking Spam as I can with PopFile running on my OE, both on the same mail accounts. On Poco, I am running Strict Bayesian with the other filters disabled.
Twice I have deleted the DBGood.ini and DBSpam.ini and retrained Poco's Bayesian Filters but I seldom see better than 96%. which I have today. I presently have 13,988 Junk Words and 7,062 Good Words.
By contrast, PopFile on OE is at 98.85% today running on the same mail accounts. Yes, I know I can disable Poco's Bayesian Filters and use PopFile but I really want to try and get everything done with Poco.
When I have some Spam messages which were not filtered out, I highlight them and then Shift+Control+- to move them to the Junk Mail folder. It is my understanding that this action also trains Poco's Bayesian Filters. Am I correct? It certainly changes the statistics.
Poco's implementation of Bayesian Filtering seems overly complicated in regards to training as compared with PopFile which I can train in two days to get 98+%.
