Thunderbird Community Forum

I have been using maildir as the message storage format for six months. I have known that the implementation is not complete and that there are several known bugs, so using it is risky.

My reports that I have not experienced any problems may have encouraged other people to use maildir, so now I must report a problem.

Twice recently, my IMAP inbox did not show all messages. Repairing the folder worked the first time. The second time, repairing the folder causes all messages in the folder to disappear. Worse, it seems that it deleted the inbox file in the file system.

I do not know if this data loss was due to maildir. It may have been.

I have returned to using mbox.

Last week my usually reliable 'Thunderbird 115.8.01 on iMac 10.13.6 has suddenly gone haywire.

* In the folder pane, multiple folder duplicates reappearing even after deleting them. (See images) * And when I delete messages, they appear in the trash folder, only to disappear and repeatedly reappear - back into the message INBOX. * Also, after making a change in the Notification section to turn off the notice sound, and although the sound turned off, so did the auto-disappear function. Now I have to manually "close" each and ALL notification notices one-by-one. The new problem is: now the notification option section has disappeared in settings. (No image for this one. Nothing there!) Bug? Or something else?

Please help. P.S. I ran both of my antivirus programs twice. Each over different days and both declared' my system clear and clean.
