Why the heck doesn't this work? (PHP / Flash mail form.)

I’m trying to make a really basic contact form using Flash and PHP. I’ve done this many times before, but this particular one doesn’t work at all. :look:

I’m starting to rip my hair out.

Here is my PHP file, which is in the same directory as the .SWF file:

<?php
$sendTo = "ryanragona@gmail.com";
$subject = "Ragonadesign.com Contact Form";
$headers = "From: " . $_POST["name"];
$headers .= "<" . $_POST["email"] . ">
";
$headers .= "Reply-To: " . $_POST["email"] . "
";
$headers .= "Return-Path: " . $_POST["email"];
$message = $_POST["message"];
mail($sendTo, $subject, $message, $headers);
?>

I’ve attached my .FLA file. It behaves just fine locally (doesn’t send me an email, of course, but it does go to the ‘thank you’ screen and appear to work) but when I put it on my server it doesn’t do a ■■■■■■ thing.
:fight:
http://ragonadesign.com/contact.html

I’m going nuts. :crazy: I have no idea what I botched with this one. Any ideas?

Thanks.

See lower post for .FLA file attachment.
