Thunderbird Community Forum

I have emails from several people that are all automatically going to a trash folder and being marked read. All of them share the same domain address but from different people. If I move them to the inbox they move on their own back to the trash folder. Help! I have tried all the online advice and nothing seems to help. What can I do to stop this?

The upper task bar on Thunderbird used to have an option that you could erase any email had a junk flame beside it. That way I could erase them all together when I received a spam email.

   I don't have that option on my upper task bar any more.

I have turned off every junk filtering option in Thunderbird, globally and for each account, yet the application started and continues to mark nearly every incoming email I receive as possible junk -- even emails from MOZILLA... It is not my ISP, nor my email provider, as they are not filtering junk, either. The banner on the preview window says "Thunderbird thinks this message is Junk mail", so that tells me it is THUNDERBIRD that is doing this. How can I get the app to stop??? There are no helpful conversations in the forum, since I've tried all of the solutions that were presented. I'm about to just delete the app and use something else which is a shame since I've been using Thunderbird for probably 20 years, but I cannot continue if this problem does not stop.
