Pegasus Mail's spam filter, as it were, learns particularly well from the mistakes it makes — if you correct them. Fortunately, this is particularly easy, too.
Train the Bayesian Spam Filter in Pegasus Mail
To teach the Spamhalter Bayesian junk mail filter in Pegasus Mail what you perceive as spam and what as good mail:
- Drag a good message misclassified as spam from your spam folder to any other folder (such as the New mail folder, for example).
- Drag spam not detected by the filter to the spam folder (as defined in the Spamhalter preferences).
Train in Place
Alternatively and if you do not like to move mail around, you can classify or re-classify any message in place:
- Click with the right mouse button on the message or messages you want to classify.
- Select Spamhalter classification from the menu and
- choose Train Message(s) as Spam or Train Message(s) as Not-Spam.
