How do you set a default automatic email notification using Dreamweaver

Hello:

I am currently creating a form on a webpage using Adobe Dreamweaver. This form is used for users to register for an event and I would like when they are finished filling out the form that the 'Submit' button autmatically sends that information from the form to a default email address. This button would not send the user to Outlook, it would just automatically send the information to the recipient address. I've seen a few websites that have this capability so I'm pretty sure that it is possible to do it, I just don't know how. Much help would be appreciated!!
