SMTP on NT4 Web server

[biff]

Hello,

Wonder if any one can help me with this:

I have been tasked to setup SMTP on a NT4 web server as a developer created an intranet page that sends out emails to various users. The idea is that once the user has selected the email recipients on the intranet page and submitted the incident form this will go via SMTP (on the web server hosting the web page) to a Exchange 5.5 server and onto the users mailboxes within the business.
I have installed SMTP on the web server (from within NT4 Option pack - IIS Web Server 4) and am now at a loss of how to point the SMTP to the exchange server. Can anyone help/point me in the right direction ?

Thanks in advance.
