Well, if you TELNET to the SMTP port of a system running MultiNet and type
HELP, it will indeed list SAML and SOML as valid commands.  They will, however,
only send mail, and not interactive messages.  And, if you try SEND FROM:,
the SMTP server will cheerfully tell you "502 Command not implemented".

A question.  What should an SMTP server that supports the SEND/SAML/SOML do
if RCPT TO: specifies a non-local user?  I just took a (very) quick glance 
through RFC 821 and didn't see anything...

Does anyone see much interest in this functionality being supported? 
Particularly in the SMTP server?
