Anybody familiar with Hostgator (formail) mail forms?

Apparently, hostgator doesn't allow php programming, so I tried to convert my old form into their format. The form seems to work and even redirect to the desired page, but no message to my inbox. Can someone please help me? Here's the form:



<form id="contact-form" name="contact-form" method="post" action="http://www.mydomain.com/cgi-sys/formmail.pl">
<input type="hidden" name="recipient" value="sales@myemail.com">
<input type="hidden" name="subject" value="Inquiry">
Inquiry<br><br>
<p>
<label>Name:<br />
<input name="Name" type="text" id="FName" size="30" />
</label>
</p>
<p>
<label>Email:<br />
<input name="Email" type="text" id="Email" size="48" />
</label>
</p>
<p>
<label>Subject:<br />
<input name="Subject" type="text" id="Subject" size="48" />
</label>
</p>

<p>
<label>Message:<br />
<textarea name="Message" id="Message" cols="50" rows="7"></textarea>
</label>
</p>
<p>
<label>
<input type="submit" name="submit" value="Send">
<input type="hidden" name="redirect" value="http://www.mydomain.com/pages/thank_you.html">
</label>
</p>
</form>
