I need help, my autoreply isn't working

I’ve spent the last two days trying to add an autoreply email function to my web page. It seems that there are tons of tips out there, but every time I try, it fails. I’m not sure what I’m doing run, and I’m feeling pretty stupid about the whole thing. I hope someone can look at this and tell me why I keep getting:

Warning: mail() [function.mail]: SMTP server response: 550 [email protected] No such user here in E:\inetpub\vhosts\yourdomain.com\httpdocs\testy.php on line 56

here is the code:

$your_email =‘[email protected]’;// <<=== update to your email address
$autosubject = “Thank you for requesting your Free Quote”;
$errors = ‘’;
$Name = ‘’;
$Email = ‘’;

$user_message = ‘’;


$Name = $_POST['Name'];
$Email = $_POST['Email'];

$user_message = $_POST['message'];
///------------Do Validations-------------
	$errors .= "\n Name and Email are required fields. ";	

// validate an email address
if( !preg_match("/^[_a-z0-9-]+(.[_a-z0-9-]+)@[a-z0-9-]+(.[a-z0-9-]+)(.[a-z]{2,3})$/i", $Email) ) {
$errors .= “\n You have entered and invalid email address”;

$errors .= “\n Bad email value!”;
//send the email
//send the email
$to = $your_email;
$subject=“there is an email from a customer”;
$from = $Email;
$ip = isset($_SERVER[‘REMOTE_ADDR’]) ? $_SERVER[‘REMOTE_ADDR’] : ‘’;

	$message = "This is the message from the customer";

$message2 = “This is the message to the customer”;

$headers = “From: $from \r\n”;
$headers .= “Reply-To: $Email \r\n”;

$headers2 = “From: [email protected]”;
$headers2 .= “Reply-To: $your-email \r\n”;

mail($your_email,"$subject","$message",“From: $Name <$Email>\n” . “MIME-Version: 1.0\n” . “Content-type: text/html; charset=iso-8859-1”);

mail($from, $autosubject, $message2, “From: Me <$your_email>\n” . “MIME-Version: 1.0\n” . “Content-type: text/html; charset=iso-8859-1”);

header(‘Location: http://www.mydomain.com/thank-you.html’);

function IsInjected($str)
$injections = array(’(\n+)’,

return true;
return false;

<?php if(!empty($errors)){ echo "
