How to narrow down disappearing mail problem
I recently hat some issues with one of my accounts. At first some random mails disappeared right after receiving them, which made me question my sanity. Last week, I was able to witness a mail being recieved, appearing in search results, disappearing in the client and disappearing the mail from the server about a minute later.
While I was still wondering about this and looking for solutions (I tried the "Repair Folder" last week), I found no apparent changes, until yesterday, when about 9 months worth of emails turned into thin air. (Not in the inbox, not in the trash, not in the archive or on the server). Fortunately our IT department has backups and could also confirm my suspicion that the deletion was issued from Thunderbird.
I think there is a severe bug somewhere, but at the current moment I don't have the smallest clues to write a useful bugreport. Where would you start collecting evidence for this?
(Running Thunderbird, version=128.6.0, on Windows10, when this happened)
Thanks, Daniel

Do you have any Message Filters that say to perform a 'Delete Message' ? If you use Message Filters there is a 'Filter Log' button - click on it. If it's not enabled then select the 'enable' checkbox so it's useful to see what's filtering and where in the future. If it is enabled then it should give you a list of what has been moved deleted etc. That will tell you what filter (if any) is performing the delete. Then you can modify the appropriate message filter and -or selecting 'Move message to' and select the server Trash folder.
