Send kode

Er det nogen der kan se hvorfor denne kode ikke virker? Den skulle gerne sende hvis to og goto er udfyldt:

<?
if (isset($_POST['to']) and isset($_POST['goto'])) {
  $myname = $_POST['name'];
  $myemail = $_POST['email'];

  $contactname = $_POST['to'];
  $contactemail = $_POST['to'];

  $message = "Fra (Navn): " . $_POST['name'] . "\r\nFra (Email): " . $_POST['email'] . "\r\nFirma: " . $_POST['company'] . "\r\nTekst: " . $_POST['text'];
  $subject = $_POST['to'];

  $headers .= "MIME-Version: 1.0\r\n";
  $headers .= "Content-type: text/plain; charset=iso-8859-1\r\n";
  $headers .= "From: ".$myname." <".$myemail.">\r\n";
  $headers .= "To: ".$contactname." <".$contactemail.">\r\n";
  $headers .= "Reply-To: ".$myname." <$myreplyemail>\r\n";
  $headers .= "X-Priority: 3\r\n";
  $headers .= "X-MSMail-Priority: Medium\r\n";
  $headers .= "X-Mailer: MobileServices";

  if (mail($contactemail, $subject, $message, $headers)) {
      header($_POST['goto'] . '&send=true');
  } else {
      header($_POST['goto'] . '&send=false');
  }
} else {
  header('index.php');
}
?>
