That's nice to know. :-)

My dovecot is running alongside another IMAP server.  Dovecot, with SSL
enabled, runs on port 994.  What I really wish to do, is to make it an
SSL-only service.

Thunderbird, in my test setup, is configured to use SSL.  I did notice,
though (if a bit unexpectedly) that the service on port 994 is plain,
albeit with STARTTLS.  Mutt and Apple's mail recognize that, switch
to TLS, and work.  Maybe Thunderbird doesn't handle this equally gracefully;
will try tomorrow.
