I’m currently using SpamStat to filter my mail.
This evening I got 172 mails. Of these, 138 were recognizsed as spam. Of the remaining 34, another 22 where not recognized as spam. Those are 13% false negatives. Only 12 messages were legitimate. :__
I checked the subjects of the last 150 mails in my spam folder, and found no false positives.
