Sending form data to an Email

Hi everyone, I'm trying to take data from a form and email it to a specified email address. I'm using the .NET 2.0-3.5 method of doing this with the System.Net.Mail classes. My problem occurs when I try to setup my connection to my server. My webserver is hosted but our exchange server is local to our network. Port 25 is open on our network firewall to allow smtp traffic through. The error that I get is: "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond " Any Ideas? Thanks, -Jordan ...
