The rate at which new tokens are added is somewhat the same as the rate that old tokens are discarded. I assume you are auto-learning. It looks like if nothing else, you might have to feed stuff like the spam in question to Bayes. You can adjust the auto-learn thresholds down, this might help a little, possibly something like: bayes_auto_learn_threshold_nonspam -0.5 bayes_auto_learn_threshold_spam 9.0 If you quarantine, consider feeding all the spam in your quarantine to Bayes (after you remove any false positives). Sometimes spam like the one in question will score low on Bayes, but high enough on other stuff to get quarantined. I have a relay server but I use the virtual map to fork a copy of my personal mail to local Maildir style folders. I also quarantine locally to a mail box and use Courier IMAP to access these two accounts. I move spam in my account to a spam folder and check the quarantine for false positives (which almost never happens). Once this is handled, I run a script to learn everything - ham and spam. Everything in both accounts is disposable at this point, so my script also deletes everything once it is learned. I admit I don't do it every day, but at least two or three times a week. I also have a script that deletes anything older than 30 days from both accounts - simply so the server won't croak if I should happen to. :) Gary V ------------------------------------------------------------------------- Take Surveys.
