Your bayes_auto_learn_threshold_nonspam should be a LOT lower than 6. If you've actually been learning emails which score 5.9 as non-spam then you've most likely poisoned your bayes database, especially with 2.55 as many spams are now being proliferated to deliberately score less than 5 with SA2.55 - you should probably clear out your current db and re-run sa-learn on your spam/ham corpus.
Additionally bayes_auto_learn_threshold_spam is set rather low (at 8) - you might learn non-spam as ham, giving you further glitches. The defaults (0.01 for nonspam and 12 for spam) are not arbitrary values, but values that have been found to generally work well in many different areas, I wouldn't bother trying to tweak them unless you find you have a problem. Remember: If it's not broken, don't fix it. -----Original Message----- From: Larry Gilson [mailto:[EMAIL PROTECTED] Sent: 28 October 2003 20:20 To: [EMAIL PROTECTED] Subject: [SAtalk] Bayes spam-ham or ham-spam ratios I am using 2.55. If the answer is different for 2.60, please answer with respect to 2.60 as I will be upgrading *very* soon. I am experimenting with Bayes in a site-wide/gateway configuration. One thing that I believe is affecting my tests is the external Procmail whitelist. I find the number of spams learned to the number of hams learned extremely large. What is the ratio of ham:spam or spam:ham (2:1, 3:1) that Bayes becomes inneffective? Does either ratio make a difference? I am thinking in terms of numbers of messages learned. Should I be thinking differently? Also, my local.cf has the following bayes_auto_learn_threshold_nonspam 6 bayes_auto_learn_threshold_spam 8 Is this appropriate or did I misinterpret the Mail::SpamAssassin::Conf doc incorrectly.
