I am experiencing a persistent "ghosting" issue where deleted messages reappear in the "All Mail" folder. Environment: Mac Mini M2, macOS 15.2, Thunderbird 140.7ESR. Configuration: Gmail IMAP with "Auto-Expunge OFF" and "Immediately delete the message forever" selected in Gmail Web settings. Behavior: Using Shift+Delete or emptying the Trash in Thunderbird appears to work locally, but upon restart/re-index, messages return to the "All Mail" folder. Even after 2+ days, a search on the Gmail web interface still reveals the "deleted" items. Issue: The EXPUNGE command does not seem to be successfully committing to the Gmail server in this specific version build. Note that the TB has gone through some major rebuilds from 140.6 back to 128 ESR to 140.7ESR in the period from early Jan till 2 weeks ago. Very recently, TB became once again very slow on a start up, including after rebuilding of the large All Mail file of 66K items. A month ago, I added Satechi with 2TB drive split evenly between Time Machine and Other data. Significant oscillations took place in free memory on the MacHD between 60BG and 10 GB, currently at 58GB. Safari is my browser.
