I only have two clients configured: Thunderbird 78.13.0 on Linux and
Thunderbird 91.2.1 on Windows. Behavior is the same on both.
I will see if I can get another client configured. Windows Mail is
included on Windows 10, so I can try that. I have a client system
running Ubuntu, and I bet that there are a LOT of mail clients available
there.

The message is deleted by dovecot immediately. I double checked this by
purging a message on my Linux client and saw the message immediately
disappear on my Windows client. It happened even faster than I would
have expected. IMAP seems to be a very good protocol! I can't say it
definitively without more evidence, but the problem *seems* to be in
FTS, not imap or core dovecot.

When I have some real time available, I will look into debug logging.
I'm going to have to research exactly where to put those config options.
Thanks,
