You have set the action property to fire the mail client up, that's why it's popping up.
If you want to have a normal form with a submit button you need to post the information to a server-side script that has access to an smtp service,
e.g.
Code:
<form action="http://mydomain.com/email.aspx" method="post">
Name:
<input type="text" name="name"><br>
Email Address:
<input type="text" name="email"><br>
Domain Name:
<input type="text" name="domainame"><br>
<input type="submit" value="Submit">
</form>
I'm sure your host will have an smtp service, so this means you just have to implement some php or asp/asp.net or even pearl if you don't have access to any of the above.
