ozzzo Posted December 14, 2006 Share Posted December 14, 2006 I sometimes get spamcop emails saying "IP.IP.IP.IP is an open proxy." What testing is done to determine this? I've tried the tests listed at http://www.spamcop.net/mky-proxies.html but they always say it's not an open proxy. Link to comment Share on other sites More sharing options...
