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.
