Subject:	SCOUG-Programming: SMTP handshaking ?

Content Type: text/plain

I'm writing an email client utility. So far my code does the DNS lookup
on the mail server domain name and then opens a socket to the server on
port 109. (I presume that's the proper port - I looked in
\mptn\etc\services and found it. There's also port 25 but I seem to
remember that's not the proper one.)

RFC 821 doesn't have the handshaking sequence I need. Can anyone point
me at the document that tells the handshake sequence for asking if
there's any mail waiting on the server? I assume there are USER and
PASSword messages involved, maybe HELO and RSET, plus a command that
queries the status of the user's mailbox.

Thanks,

- Peter
