Code

function httpbl_se($ip = NULL) {
  if ($response = httpbl_dnslookup($ip)) {
    $iplink = _httpbl_iplink($ip);

    // positive threat, type is search engine (0)
    if ($response['threat'] && $response['type'] == 0) {
      if (variable_get('httpbl_log', 1) > 2) {
        watchdog('httpbl', t('Search engine lookup for %ip was positive (%response)', array(
          '%ip' => $ip,
          '%response' => $response['raw'],
        )), WATCHDOG_NOTICE, $iplink);
      }
      return TRUE;
    }
    else {
      if (variable_get('httpbl_log', 1) > 2) {
        watchdog('httpbl', t('Search engine lookup for %ip was negative (%response)', array(
          '%ip' => $ip,
          '%response' => $response['raw'],
