I have just been using SpamSieve for a few weeks & generally so far - so good - since loading SpamSieve accuracy is 96.5% - so presumabaly current outcome is better than 96.5%. I do however have one mail account that receives a lot of spam & SpamSieve seems to be making no progress with this stuff. Is there anything else I can do - perhaps I should try using the “more agressive” setting?
You can see the accuracy for different time periods using the Set Date button at the bottom of the Statistics window.
Probably something isn’t setup properly. Please make sure that the SpamSieve rule(s) in your mail program are at the top of the list.
