The "lost connection after UNKNOWN" is because your thunderbird is
using wrappermode TLS, commonly used on port 465.  You need to set
tbird for "STARTTLS".

Yes, but that isn't the problem.

Unreadable, I'm not even going to try.

Good, TLS connection to postfix works when the client is
configured for STARTTLS.

But the client never sent an AUTH command to postfix; if it had,
it would be logged.  Relay access is denied because the client did
not AUTH.

Unreadable, but this is shorter, so I'll try:

STARTTLS issued, TLS connection established.

This time apparently the AUTH worked.  Postfix would have logged a
similar auth successful line.

But relay is still denied.  Probably because you forgot to add
"permit_sasl_authenticated" to your postfix restrictions, or added
it in the wrong place.  Posting a readable "postconf -n" will
probably help.

No, nothing to do with DNS.

Ah, and that's why you get relay access denied.
