Give a try to ports/mail/dspam; it uses a combined bayesian algorithm.
If you have problems just email me privately and I'll be glad to help.
but it's extremely easy to setup. User must just fw the spams to an
alias you set up for them.
Here are some statistics:
NGStats for Jan 28, 2004:
43 Systems Participating
639,217 Spams Caught
1,008,491 Innocent Msgs Scanned
758 False Positives
0.07% False Positive Ratio
After the training period (some of this systems are very recently
installed), the results are better, about 99.75 - 99.9% with 0.01-0.10%
>From which uses something called Bayesian Dobly to filter Bayesian Noise
the results seems to be 99.953% ratio and no false positives.
