Thunderbird and Junk / Spam Messages
To deal with the large amount of unsolicited email ("spam" or "junk mail") that most people have to cope with, Thunderbird uses an adaptive filter that learns from your actions which messages are legitimate and which are junk.

Junk filter options
The filter is enabled by default. You can set system-wide preferences that determine what happens to messages marked as junk. These settings will be used by all your email accounts (although some settings can be overridden in the account settings, as shown below). To access the preferences, click, select the panel and then select the tab.
Per account settings
The configuration in the account preferences for each of your email accounts will override similar settings in the preferences described above. Clickand select in the left pane for the account to see these settings.

As you mark messages, Thunderbird learns the characteristics of your junk mail and can start automatically classifying messages.
Tell Thunderbird what is NOT junk
During the early learning stages, it is a good idea to look at the messages that have been classified as junk and un-flag any that have been incorrectly classified by clicking on thebutton.
