Hi
Can someone help, or direct me to the correct ng, my question is this:
RFC821(SMTP) is used to send mail from one smtp server to another,
but how does the client program, e.g. outlook express, interface to
the smtp server, does it use RFC821 as well ?

Hello,

Yes, email clients use the same SMTP protocol, the only difference is the
direction (in most cases, email clients do "relaying"). MS Outlook in
Corporate (?) Mode however, uses MAPI to submit emails to Exchange.

The client uses the SMTP server to send, but requires a POP3 server to
receive.
