function reroute_email_test_mail_alter(&$message) {

  // Only alter the email for the key test_reroute_email.
  if ($message['key'] != 'test_reroute_email') {
    return;
  }

  // Prevent Warning from drupal_mail because body is not an array, only if
  // message has already been processed by reroute_email.
  if (is_string($message['body']) && isset($message['headers']['X-Rerouted-Mail-Key'])) {

    // Record to be checked in test in the log entries.
    watchdog('reroute_email_test', 'A String was detected in the body: <pre>!body</pre>', array(
