My server has a personal, family website on it, among other things. Email sent to the people using this family site gets forwarded to Cox.net e-mail addresses. On Tuesday, Cox.net started bouncing the forwarded e-mails. The errors in the bounces e-mail say that the IP address of my server is "locally blacklisted".
I have verified that my server's IP address does not show up on any IP-based blacklist that I can find. I tried sending e-mails to [email protected], [email protected], and to my server provider (800Hosting) and no one has responded.
I talked, online, to a Cox.net representative, and he said to wait 24-48 hours and it should automatically come off the blacklist. He was just an online tech support person, so I do not know how reliable his information is.
It has been close to 48 hours now. Maybe I just need to wait a little longer, and it will magically come off the blacklist, but I want to talk to someone at Cox.net who can help.
Does anyone think it will come off the blacklist, or should I continue looking for a contact at Cox.net to get help?
This doesn't really help in your resolution. But if you have users forwarding their mail from your server to their @cox.net e-mail address, then this may be what is causing your blacklisting. When mail is forwarded from your server to another server (in this case, cox.net) then if spam is forwarded, the final destination server (cox.net) will see that spam as being sent from your server. Because of this, cox.net may be flagging your server as a spam source.
Cox.net is allowing my e-mail to get through again. I don't know if it is because the 24-48 hour waiting period ended, and the tech guy was right, or if it was the e-mails I sent to Cox asking to get off the blacklist. Either way, it is resolved, for now.
