Is there a way to allow tlsv1.0 minimum for unauth connection and allow

Why would you want unauthenticated connections on port 465? (smtps).
It's AFAIK a submission port.
SMTP<->SMTP is (should be) always on port 25, with or without STARTTLS.
Port 465 is submission with TLS wrapper-mode, and port 587 is submission
(with or without STARTTLS).
I don't know if there are any smtp clients (in the sense of postfix smtp
"client") using 465 for sending to a smtp server (in the sense of postfix
smtpd..)
