I'm using spambayes as my only spam filter, and I am very pleased with it. False negatives and false positives are both very rare. It has an "unsure" category for anything it's not sure about, which turns out to be spam most of the time; the thresholds are adjustable. Unfortunately it's not in Debian, not sure why. I got it from sourceforge IIRC. > Assuming that it is a useful way of dealing with spam, what's the best > way to implement it?

The filter. dman has a useful exim config hack that makes exim use the filter as a transport; this has been referred to on the list a few times recently. His example uses spamassassin, which can do Bayesian filtering as well as its other stuff. -- Pigeon Be kind to pigeons Get my GPG key here: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x21C61F7F
