Hey,

Bottom line, you as the creator of the site, need to know the SMTP details of an SMTP Server that you want to use to send the email. You will likely already have this service from your web host, so they should be able to tell you the details.

Then, on the server side, you take all the information from the form, place it into an email, and then send it. The client, i.e. the user of your application, doesn't need to provide any email details, as they are already known.
