function reroute_email_module_implements_alter(&$implementations, $hook) {

  // Testing with isset is only necessary if module doesn't implement the hook.
  if ($hook == 'mail_alter') {

    // Move our hook implementation to the bottom.

      $group = $implementations['queue_mail'];
      unset($implementations['queue_mail']);
