Start with http://www.ietf.org/rfc/rfc821.txt

            RCPT <SP> TO:<forward-path> <CRLF>

         This command gives a forward-path identifying one recipient.
         If accepted, the receiver-SMTP returns a 250 OK reply, and
         stores the forward-path.  If the recipient is unknown the
         receiver-SMTP returns a 550 Failure reply.
