Formulario de conto em flash + Php

Boa Tarde, Tenho um formulario de contato em flash, mais quando vou enviar a mesagem não está chegando para o email.

Php

<?php

// read the variables form the string, (this is not needed with some servers).

$subject = $_REQUEST["subject"];
$message = $_REQUEST["message"];
$sender = $_REQUEST["sender"];

// include sender IP in the message.

$full_message = $_SERVER['REMOTE_ADDR'] . "\n\n" . $message;
$message= $full_message;

// remove the backslashes that normally appears when entering " or '

$message = stripslashes($message);
$subject = stripslashes($subject);
$sender = stripslashes($sender);

// add a prefix in the subject line so that you know the email was sent by online form
$subject = "Contact form ". $subject;

// send the email, make sure you replace email@yourserver.com with your email address
if(isset($message) and isset($subject) and isset($sender)){

	mail("xxxxxxxx@hotmail.com", $subject, $message, "From: $sender");
}
?>
