function mailingListSub($email, $listname, $domain) {
   $pwd  = substr(md5(time()),0,6);
   $args = "&email=".urlencode(stripslashes($email)).

   $header .= 'Content-Length: ' . strlen($args) . "\r\n";
   $header .= "Connection: Close\r\n\r\n";
   $fp = fsockopen($domain, 80, $errno, $errstr, 30);

   if (!$fp) { // ERROR
       fclose($fp);
       return false;
