That's probably because 821 never even mentions TELNET. It's implemented  
on TCP.

It just so happens (not quite by accident) that using ASCII over TCP/IP is  
compatible with TELNET over TCP/IP.

You have to go back to RFC 722 to actually see a mention of TELNET. And  
even then, it doesn't refer to what SMTP does.

TELNET is irrelevant when talking about mail standards.
