Assuming you don't have a server-side methods like PHP, ASP, Perl, etc. the only thing I think you can do is something like this:

Code:
<form action="mailto:[email protected]" enctype="text/plain"><div>
  Name: <input type="text" name="Name"><br>
  Subject: <input type="text" name="subject"><br>
  Comments: <textarea name="comments" cols="20" rows="10"><textarea><br>
  <input type="submit" value="Send Comments"><input type="reset" value="Clear Form">
</div></form>
But that will just open the user's e-mail client.
