I believe this is simply Postfix telling me the connection isn’t properly authenticated, as setting up the exact same credentials on another client (non OE) works.  It is only with OE on XP that I am unable to send/authenticate.

Sounds like a problem with postfix talking to your XP client, not a
dovecot problem.

If you've changed the tls settings in postfix recently, you likely
broke compatibility with older clients.  If you need further help,
feel free to ask on the postfix-users list.  Be sure  to include
"postconf -nf" and "postconf -Mf" output, along with related log
entries demonstrating the problem.
