Junk messages not moved

Symptoms

Problems some people have experienced with Thunderbird's Junk Mail Controls:

• Thunderbird marks messages as Junk as expected, but it stops moving messages to the Junk folder. Sometimes it starts moving messages again; sometimes some messages are moved but others are not.

• Manually running junk filters ("Tools -> Run Junk Mail Controls on Folder") works as expected, including moving all messages marked as Junk to the Junk folder.

• The Junk Mail Log ("Tools -> Junk Mail Controls -> Junk Mail Log") may erroneously say the messages have been marked as Junk and moved. (needs to be verified)

Solutions

As of 17 November 2004 this problem is a known bug in Thunderbird 0.9 and possibly earlier versions. These solutions have been proposed, but none are verified to always work:

• Workaround: manually run the junk-mail filter: "Tools -> Run Junk Mail Controls on Folder".

• Compact the Junk folder.

• Delete all messages in the Junk folder.

• Not for users with limited computer skills: close thunderbird, find your profile folder and delete the "Junk.msf" file. WARNING: Deleting the wrong file can cause loss of your e-mail.

• Not for users with limited computer skills: close thunderbird, find your profile folder and delete the "Junk" file and "Junk.msf" file. Create a new, empty "Junk" file. WARNING: All messages in the Junk folder will be irrevocably lost. Deleting the wrong file can cause loss of other messages.
