FTP Extension:




This note describes an extension to the File Transfer Protocol
provides for "sending" a message to a logged-in user, as well
variants for mailing it normally whether the user is logged in or not

Several systems have a SEND command or program which sends a
directly to a user's terminal. On the SAIL (SU-AI) and
(MIT-(AI/ML/MC/DMS)) systems the concept has been broadened to
SEND'ing to users on other network sites; to support this, three new
commands were added which have a syntax identical to the existing
command. For reference, the latter is

MAIL <recipient name>
If accepted, returns 350 reply and considers all succeeding
to be the message text, terminated by a line containing only
period, upon which a 256 completion reply is returned.
errors are possible

The new commands, with their special replies, are

XSEN -- Send to terminal

Returns 453 failure reply if the addressee is refusing or
logged in

XSEM -- Send, Mail if can't

Returns 009 notification reply if message cannot be SENT

XMAS -- Mail And Send. (couldn't resist this one

No special replies

Note that for XSEM and XMAS, it is the mailing which determines success
not the SENDing, although XSEM as implemented uses a 009 reply (
addition to the normal success/failure code) to indicate that
the SEND failed, an attempt is being made to mail the message instead
There are no corresponding variants for MLFL, since messages
in this way are generally short, and neither I nor Brian
(implementing respectively the ITS and SAIL servers) wanted to bother

if you see any problems within the linking, don't worry be happy,
this is version 0.1 of the Relevance System and you gotta expect some crappy subroutines sometimes,
just be content we did not write this in Java, which would have made this "bigger and better" HAHAHHA.
