Hello,

G.6.  Clarify where the protocol stands with respect to submission and TLS 
issues
 1.  submission on port 587 or port 465

RFC 8314 says in the Introduction:

â??This memo now recommends that:

o Connections to Mail Submission Servers and Mail Access Servers be made using 
"Implicit TLS" (as
defined below), in preference to connecting to the "cleartext" port and 
negotiating TLS using the
STARTTLS command or a similar command.â??

My reading is thay the above text clarifies to prefer 465 over 587.

Some of us disagree about how well this advice matches reality. See
you at the BOF.

R's,
John
