Can you please enable telemetry and tell me what it shows in this case.
You'll need to create a directory /var/imap/log/$username/ where $username
is your username.  You'll need to make sure that directory is owned by
the cyrus user.

I'd like to find out what's going on!

All looks fine.

I don't run this myself, but lots of people do - it should be working
fine.  I should probably set up a test instance with it on!

This is the only thing I can see that looks maybe-strange.  Are you
actually using a non-lower-case username to log in?  I wonder if there
are bugs in the "detect if it's your INBOX" code if the username doesn't
actually match up.
