Input text passing extra info to PHP

So I’m building a little contact form in flash and it works, but it is passing along all of the font styling information into the email sent to the client. Kind of annoying. I want it just to send the plain text.

Here’s what I’m using:

This code is in the actionscript, picking up the input text fields and posting them to the PHP file. It also tells a status box to update with current info:

loadVariables("send_email.php?flashmo=" + random(1000), this, "POST");
message_status.text = "sending...";
var i = 0;
function check_status()
{
	if( success == "yes" )
	{
		message_status.text = "Your message was sent successfully!";
		play();
	}
	else if( success == "no" )
	{
		message_status.text = "Your message could not be sent. Please try again.";
		gotoAndStop("stop");;
	}
	if( i >= 20 )
		clearInterval(interval_id);
	i++;
}
var interval_id = setInterval(check_status, 400);

This is the PHP form:

<?php
$contact_name = $_POST['name'];
$contact_email = $_POST['email'];
$contact_phone = $_POST['phone'];
$contact_message = $_POST['message'];

if( $contact_name == true )
{
	$sender = $contact_email;
	$receiver = "chris.graue@gte.net";
	$client_ip = $_SERVER['REMOTE_ADDR'];
	$email_body = "Name: $contact_name 
Email: $sender 
Subject: $contact_phone 
Message: $contact_message 
IP: $client_ip 
Flash contact form from La Bella website";		
	$extra = "From: $sender
" . "Reply-To: $sender 
" . "X-Mailer: PHP/" . phpversion();

	if( mail( $receiver, "Flash Contact Form La Bella - $phone", $email_body, $extra ) ) 
	{
		echo "success=yes";
	}
	else
	{
		echo "success=no";
	}
}
?>

And this is the email I receive:

Name: <P ALIGN="LEFT"><FONT FACE="Helvetica Neue" SIZE="12" COLOR="#492F92" LETTERSPACING="0" KERNING="0">Some Jerk</FONT></P>
Email: <P ALIGN="LEFT"><FONT FACE="Helvetica Neue" SIZE="12" COLOR="#492F92" LETTERSPACING="0" KERNING="0">jerkemail@email.com</FONT></P>
