just a week or two ago I read discussion where the 465 was preferred,
because SSL is mandatory there, so there's no chance for clients to

SMTPS (which is what you use on port 465) is an obsolete protocol that there's

I know.
SMTP+TLS on port 587 is the modern solution.
I have just explained that I have _read_ opinion of someone who preferred
SMTPS and why they did.
You can read it at:

You should configure your MTA not to accept unencrypted connections on
port 587.
Why do you tell _me_?
I have encountered an issue with submission/starttls a few years ago, so,
when I configure mail submission, I set up both submission+starttls and
smtps.
