This is what I have own master.cf and it works perfectly with iOS, iPadOS, and
macOS Mail.
submission inet n - n - - smtpd

I leave mail settings at “Automatically manage connection settings” and Robert
is your father’s simian brother.
The keys are that submission uses smtpd_tls_security_level and smpts uses
smtpd_tls_wrappermode
Also, as Viktor eluded to, you should not be using port 25 for accepting mail
from MUAs.
Though I enabled smtps a while back, I am not sure the anyone is actually using
it. I certainly haven’t seen it in the logs, but I do not keep mail/log for
very long and I don’t check for smtps in it often enough to be sure. Still, it
dodoesn’t hurt having it, and it may help at some point.
