The only substitute for good manners is fast reflexes.
for getting
mail (IMAPS/POPS), rather than for sending mail
(SMTP/STARTTLS). I don't know. If so, it might only
affect e.g. Dovecot's choice of certificate rather than
Postfix's. But chances are, if you use both, you'll
probably want them to use the same certificate.

they'll only support TLSv1.2+. The only alternative
would be to close port 25, use port 465 (TLS-only)
instead, and hope that all mail servers that want to
send them email try to use port 465. But that's not
