I Need Help With Thunderbird's Message Filtering

I did something to my Thunderbird email filters that causes most if not all new messages to go to the trashcan. Here is how my filters are set up. All of the filters are pretty much set up the same way:





Hopefully somebody can find something wrong with my setup and help me fix it.

I'm posting this here because the Mozilla help site does not allow the posting of images.

 

Your Sunjoy rule is set to "Match any", not "Match all messages". It should only catch the three From entries shown; that screenshot alone doesn't explain unrelated mail being deleted.

First untick Enabled for the deletion filters and leave Trash alone. Both "Delete Message" and "Delete From POP Server" are selected, so testing against real mail can also remove the server copy.

Click Filter Log (bottom right in your first screenshot) and enable logging. If there are existing entries for a good message, the rule name should identify the culprit. If not, temporarily replace BOTH delete actions in a suspect rule with "Add Tag", re-enable just that rule and receive a test message. That lets you see what matches without deleting it.

Could you post the conditions/actions for SpamAssassinYes and Spam? Those aren't visible in the screenshots, and their names don't establish what they actually match.

 

Thank you for replying.

I'm having a bit of trouble understanding your 2nd paragraph. I did untick Enabled for SpamAssassinYes and for Spam, but I don't know what you meant by "leave Trash alone.

I read the Filter Log and will post the results. Looks like it has something to do with "Sunjoy".

I got confused while reading your 3rd paragraph.

Here are the filter setups for SpamAssassinYes, Spam, and the filter log:







Thanks again for your help.
