Using TBird 3.0.4 for a while now and suddenly it marks ALL incoming mail as Junk and fails to move it to the Junk folder. No settings were changed all all appear to be ok. Anyone else experience this?

Have you looked at the full headers of these messages to see what their spam score is?

even mail from myself is now marked as Junk, also why isn't the supposed Junk being moved into the Junk folder as it is supposed to be? I'm afraid there has been some sort of corruption of the Junk filter internal to the app.

Did you check your junk folder config and that the folder designated for junk exists? Is this an IMAP or POP account? If IMAP, is the Junk folder local or on the server? Do you have any rules setup?

Note that my suggestion about checking your spam scores relates to mail being marked as junk by your mail server, Thunderbird doesn't write spam x-headers.

Note that this just suddenly started to happen, no setting were adjusted and all were checked and are the way I left them. Messages are being marked Junk locally, group addressed messages are not seen as Junk on another Mac with T-Bird.
