Thunderbird keeps marking non-junk messages as junk - how do I fix this?

more options

This is maddening - I have not external filters that would influence T-Bird to do this. I have marked the e-mails as Not Junk and they almost immediately return to the Junk folder (even e-mails from Mozilla are ID'd as Junk).

Is there any fix for this?

Other people reporting this problem have discovered that their provider is doing this. For a test move one of the problem messages to the Inbox under Local Folders. If it does not get marked as junk there then Thunderbird is not guilty.

I have done that multiple times. Still moves to Junk...

Just to be sure, you moved the message to the inbox of the LOCAL FOLDERS account not the inbox of your email account.
