From FreeBSD's /etc/services
smtp 25/tcp mail #Simple Mail Transfer
smtp 25/udp mail #Simple Mail Transfer
smtps 465/tcp #smtp protocol over TLS/SSL (was ssmtp)
smtps 465/udp #smtp protocol over TLS/SSL (was ssmtp)
It's an obsolete assignment, ignore it.
Beg your pardon? Hardly 'obsolete'!
It's officially obsolete. In fact, port 465 has been reassigned for a
different function. See:
http://www.iana.org/assignments/port-numbers
urd 465/tcp URL Rendesvous Directory for SSM
igmpv3lite 465/udp IGMP over UDP for SSM
...... 465 is the port for SSL/TLS *secure login* and client-server
connection, i.e. userid and passwd not 'en clair'..... etc. Nothing to do
with server-to-server relaying AFAIK....
SMTP is SMTP, and in all cases is "client" to "server". A "mail server" is
acting as a client when it is sending mail to another mail machine via SMTP.
