The Bayesian spam filter in Mozilla Thunderbird, Netscape or Mozilla identifies spam by calculating for each incoming message how likely it is junk. These calculations are based on how you have classified previous messages.
This means that Netscape or Mozilla Thunderbird can make a very good guess on what your spam and your good mail looks like. It also means that you have to train the spam filter a bit so it can get an idea what you perceive to be spam.
To train the spam filter in Mozilla Thunderbird, Netscape or Mozilla:
- Open the message you want to classify.
- Click the Junk toolbar button.
- Alternatively, click in the Junk Status column in the message list.
Either action will toggle the junk status of the message. You can use it to mark junk not (yet) recognized by Metscape or Mozilla, but you can (and should!) also use it to reclassify mail that has been wrongly labeled spam by Mozilla Thunderbird or Netscape.
If you find the spam filter in Netscape or Moziila Thunderbird classifies mail satisfactorily, you can have it move spam to a special folder automatically.
