Connecting from Outlook via SMTP

I want to develop a small SMTP server for use over s private network, how do i connect to my program using winsock from outlook express by typing in an SMTP server?

eg, if i were creating a http server, i would type http://myip/ into explorer, and listen on port 80 with winsock.

but how do i get a connection from outlook?

It's not hard. Set the server as Outlook's outgoing mail server
