I have a form with this code:

<form action="home.mpowercom.net/cgi-bin/FormMail.pl" method="POST" NAME="Contact">
<input type=hidden name="recipient" value=" ">
<input type=hidden name="redirect" value="www.bellagrandeentrances.com/thanks.html">
<input type=hidden name="subject" value="Have a question or request catalog">

//besides other fields, i have this field also:

<input type="text" id=email maxlength=75 size=25 name=Email>


When we get an email on outlook express the column "from" is empty. How do I get the email address out of the form to the header of outlook express?
Thanks
Markus
