The easiest thing to do would be to follow the code found
here, which uses mailto as the form action. Now I will say that you shouldn't use this method, if at all possible. It could work, but there are a lot of issues with it.
You're better of building something in say PHP that the form submits to and it will process the information, validate it, and then email it to you. There are plenty of tutorials out there, but
here is on I just found that might help you out.
