OK - I'm an idiot. I'll just admit that up front and get it out of the
way.
Now that that's settled, what is the difference between "SSL" and "TLS"
in a MUA - particularly Thunderbird - in a Postfix context?
I would have sworn I used to use Thunderbird with "SSL" specified and
connected to my Postfix servers fine. Now, I can only connect in "TLS"
mode. What did I break?
It's unlikely you'd forget setting up SSL. You would have likely created a
self signed server certificate and would have installed it on all clients
connecting to the server, just as must be done with web browsers connecting
to a secure site for the first time.
You've likely been using STARTTLS only, which doesn't require a key exchange
as SSL/TLS does. STARTTLS != TLS.
Huh, what? STARTTLS == Start TLS
