Training a bayesian filter with messages that it has classified correctly is still beneficial. Imagine a filter that was trained with exactly one ham and one spam message. It's probably not going to do a very good job - but imagine you get lucky and it correctly classifies a large number of messages. Training the filter with those messages will still make it a much better filter, as it will then have a much better idea of what your ham and spam look like (i.e. it has a larger statistical sample to analyze). That's the whole point of Spamassassin's autolearn plugin. It will automatically train itself as it filters, as long as a message exceeds a certain spam or ham threshold. You can configure it with: bayes_auto_learn 1 bayes_auto_learn_threshold_spam 12.0 bayes_auto_learn_threshold_nonspam 0.1 Those are the default threshold values, you can change them to whatever you want. Note that autolearning spam requires at least 3 points from the header, and 3 points from the body, so setting the spam threshold lower than 6 will be the same as setting it to exactly 6. You can see if your messages were autolearned by looking at the headers; you will see one of these: autolearn=ham autolearn=spam autolearn=no Brian -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
