Apple Mountain Lion is the fourth or so version of my Apple Mail and SpamSieve working together.
Until lately very successful with almost 100% correct filtering, every now and then a false positive.
Well trained corpus with: 3156 good news, 4077 spams (56%), 458.853 words …
Filtered news: 63.510 good news, 9799 spams, 4spams per day, 107 false positives, 709 false negatives, 98,9 correct
But since a few days I am getting loads of spams through nit knowing how it could happen.
Can’t help, can you?
