I have this script setup to send a mail to myself when someone fills out a form. What I want is the same thing mailed as a reciept to the person that filled out a form but only with a change of it's content. It should come from no-reply@domain.com so they can't reply to the reciept and the only change in the content that is mailed should be a line of added text like "This is a reciept of your inquiry - you can not reply to this"
<?
$subject="Domain.com Inquiry: ".$_GET['subject'];
$headers= "From: ".$_GET['email']."\n";
$headers.='Content-type: text/html; charset=iso-8859-1';
mail("ADMIN_EMAIL@gmail.com", $subject, "
