Thunderbird has several ways to detect "junk mail". It's easy to use: just turn the feature on, then "train" it to identify those messages that are "junk".

This page explains how to use this feature.

1. Open the "Junk Mail Controls" window

Start Thunderbird and click Tools, then Junk Mail Controls:

3. Specify the action for Junk Mail

Switch back to the Settings tab.

You can choose various actions and destinations for messages Thunderbird flags as junk. For example, to move messages into the junk mail folder, check the Move incoming messages determined to be junk mail to: box, then choose the Junk folder:

4. Training Thunderbird

To "train" Thunderbird, you need to tell it which messages are junk. To do this, right click on a junk message and choose Mark and As Junk:

That's all it takes to train Thunderbird to filter unwanted mail to a special folder.
