The reason is we received the email with the following details [spamCop (220.127.116.11) id:3200297675] but thank you for your thoughts regarding the problem. We are aware of the CBL & PBL issues and are following that up with the respective groups.
Hi, Email from our PowerMTA email server has generated problem stating we are running an open proxy on the server. The port 8080 had been open on the server but has now been closed by a firewall. Is there anyway to perform the same test Spamcop did to verify the problem has been resolved? The IP address in question is 18.104.22.168. Thanks, David
