I'm using a custom procmail setup build over the years around Bogofilter [1]. I find it still works well, even though Bogofilter is more or less unmaintained at this point. I'm only aware of one serious bug in the upstream distribution [2], but a patch for that exists. The running yearly average false negative rate for me is currently 6.5%, which isn't perfect but it's survivable. It's hard to say what false positive rate is, but over the years I can't remember an instance where I would go fishing in the spam folder for a mail I knew I should receive (I do have classification settings very much biased towards false-negative rather than false-positive) [1] http://bogofilter.sourceforge.net http://bogofilter.sourceforge.net [2] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=733622 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=733622
