That's it. Thunderbird tried to talk ssl to a plain imap service, which horribly failed.
Well, having an IMAPS-only dovecot on port 994 fixed things for Thunderbird,
Why is it on port 994 -- is that a typo?
No. I'm testing the water for dovecot deployment, and have set up dovecot side by side with another IMAP daemon (so a loaded and active mailstore is available).
Thunderbird seems to run fine now; a matter of applying the proper ssl_listen to get that port pure SSL, alongside a clear-plus-starttls one.
It looks like Mail.app treats "non-standard" ports differently. On the standard port (993), the "SSL" option seems to do pure SSL; but with another port specified, it does clean-plus-starttls (and hence fails horribly, because it's talking to a pure SSl service).
