: Thanks for any input.
Unfortunately when you use MAILTO: in the ACTION of a form, it's up to the browser to determine what to do with this action and usually the default action is to open the default email program.
The only way to send an email to someone is to send the form data to a script of some sort that can "talk" to a mail transport agent (MTA) like SendMail or the like.
I THINK there are a few "FREE" MTA's out there but I can't think of any off hand. All you need to do is find one, point your form to it (as per the MTA's instructions) and it'll do the rest for you without IE popping up a New Mail Message window.
Hope this helps!
