Jerry is correct. Well, on all but that last part, anyway :)
You need to configure your Exchange server to allow relaying from a
specific machine (like your webserver) or specific networks (like you
internal network). In the Exchange System Manager, find the SMTP
Virtual server and open the properties for it. On the "Access" tab
click on "Relay" and add the IP address of your webserver. If you
trust your entire local network you could add that, too. Just make
sure you have it set to allow relay for "only the list below" -- not
"all except the list below."
