[comp.protocols.tcp-ip] SEND et al in the SMTP mail spec

imp@solbourne.com (Warner Losh) (05/01/91)

I was wondering, does anybody know what implementations of SMTP
support the following commands:
	SEND FROM:
	SOML FROM:
	SAML FROM:

I know that MRC's TOPS-20 Mailer does, and the ITS and WAITS mailers
do.  Are there any others?

	TGV Inc.s MultiNet TCP/IP for VMS supports these.
	You can probably get more info from sales@tgv.com...

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?

I'd return an error message with code 551, myself.  RFC 821 lists this as:
	551 User not local; please try <forward-path>
Yes, I know this isn't listed as an explicit possibility under the SEND
command.  One of the few holes in RFC 821.

The ITS mailer will forward as requested and use the SEND/SAML/SOML on
the next hop as well.  This was used to support interactive messaging
between Chaos only and IP only hosts.  It will even drop SOML back to
MAIL if the next hop says "Not supported", it will bounce a SEND, I'm
not sure about SAML, probably will MAIL and bounce the SEND half.

  FTP Software's SMTP server for MS-DOS supports SEND, SOML, and
SAML.  If someone connects to our SMTP server and uses SEND it will
print the message to the screen as it's received.  If they use SAML
or SOML, the server will print the message to the screen and then
send a copy of the message to the recipients.

I did a hack to sendmail a long time ago to make it support SEND. I believe
the diffs are in the archives of comp.sources.unix on uunet.uu.net.
