Yes we allow you to run FromMail type scripts, we strongly recommend that you use the nmsFormMail script for your "form to email" script rather than any of the alternatives as it is by far the most secure FormMail script we have come across.
For additional security we recommend you give your script an alternate name rather than formail.php, formmail.pl or formmail.cgi (plus upper/lowercase varients) in order to make things more difficult for automated scanners looking for vunerable mail scripts.
