Online Form Solution

I manage one of our company's intranet sites. We're using RoboInfo software. I basically just publish documentation for our users. I want to add online forms to my pages so they can be filled in and I can receive in my inbox. I am looking at the best solution. I did have a basic html form online using POST, but the user gets those annoying popup warnings (one from IE, one from Outlook).

I wanted to create a php form, but my IT department says they can't install php on the server. Now I'm looking at an ASP form, which should work on the server. I've found scripts here that seem simple enough to set up. Do I need to know the smpt and port # to get an ASP form working? Anyway I can determine the smpt without contacting IT (they probably wouldn't tell me!). Any other solutions I can look at in creating online forms?
