I have a php challenge. Let's see who can find the solution first!

Here is your test. Below is a simply php for sending an email to yourself and an autoreply to the person filing it out. However, they way it's set up right now, you get the following errors

Warning: mail() [function.mail]: SMTP server response: 550 <customeremail@aol.com> No such user here in E:\inetpub\vhosts\yourdomain.com\httpdocs\test.php on line 56

Warning: Cannot modify header information - headers already sent by (output started at E:\inetpub\vhosts\yourdomain.com\httpdocs\test.php:56) in E:\inetpub\vhosts\yourdomain.com\httpdocs\test.php on line 58

Here is the code. Let's see who is the best:

<?php
$your_email ='ME@mydomain.com';// <<=== update to your email address
$autosubject = "Thank you for requesting your Free Quote";
session_start();
$errors = '';
$Name = '';
$Email = '';

$user_message = '';

if(isset($_POST['submit']))
{

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


    $user_message = $_POST['message'];
    ///------------Do Validations-------------
    if(empty($Name)||empty($Email))
    {
        $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";
}

if(IsInjected($Email))
    {
        $errors .= "\n Bad email value!";
    }
    if(empty($errors))
    {
        //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: Me@mydomain.com";
$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 to validate against any email injection attempts
function IsInjected($str)
{
  $injections = array('(\n+)',
              '(\r+)',
              '(\t+)',
              '(%0A+)',
              '(%0D+)',
              '(%08+)',
              '(%09+)'
              );
  $inject = join('|', $injections);
  $inject = "/$inject/i";
  if(preg_match($inject,$str))
    {
    return true;
  }
  else
    {
    return false;
  }
}
?>

@-suppress mail() and check its return value.

Oh, and

Trying to trick us into solving your problem by phrasing it as some sort of "contest" is insulting. There's nothing wrong with asking people for help if you don't know the answer.
