Training the baysian filter

Post by johnd34 »

Has anyone tried training the filter by forwarding emails to a 'spam' mailbox, or will this give negative score on the senders and not the content.
The senders will be authenticated so i can save them with the rule to always allow their mail, but would that allow them to be processed for training?

Thanks

My experience with the built in Mail Enable Bayesian is that it is virtually untrainable (in auto mode) (Years of Auto training has resulted in an epic .02% detection). Even After rigorous manual training it seems like it never gets it (At one point i had got it to a very short lived 40%. Within few months it was down to less than 10%). I've been trying to use the MailEnable Bayesian Filter since it was first introduced years ago.

If you use SpamAssassin in a box (it's difficult to train due to its daemon nature) but OOB it has a 90-95% detection rate.

I have used the ASSP Spam project several times in the past. This (used to be a great project) unfortunately due to it being "a man in the middle" solution it actually makes the spam situation worse because it auto accepts all e-mails to any sender.

I used the SpamAssassin when the new integration features were introduced in (7.0 ?) and it is really great albeit a bit of a pain to setup. My only complaint and the reason I'm not using it now is that there seems to be no way to control what e-mail is sent to it and what e-mail is not sent to it. And the Spam Assassin is insanely CPU hungry on (Windows?) running a Quad Core Xeon E5620. Our mail server relays a lot of outbound business e-mail that include large file attachments and I could find no (working) way to configure Mail Enable or SpamAssassin to ignore this e-mail.

That's merely based on my my experience using it (MailEnable Standard user since 3. and Pro since 4 or 5).
