Cox not receiving emails from Microsoft (hotmail.com, msn.com)
For a message sent from a msn.com account to a list that includes multiple cox.net addresses, eventually a non-delivery notice comes back saying all the cox.net recipients were unreachable. The message for all of them is exactly the same:
<username-deleted>@cox.net

I cannot get individual messages to my cox.net account from various Hotmail.com and msn.com accounts. I expect I'll get non-delivery notices for these in a day or two.
Something is broken. How do I get this message in front of someone who can DO something? Cox Chat and Tier 1 phone reps were typically useless. ("What device are you using? What is your operating system?") THIS IS A MAIL SERVER PROBLEM. PLEASE HELP.

Have you had the opportunity to send a message to one of the affected addresses, making it the only recipient at the time?

I started having the same issue Sunday morning. A friend who is sending emails from Hotmail through Outlook with MSN has not been able to get an email to me all week. As of yesterday afternoon, it appeared that some of the delayed emails were being received. Is the issue resolved?
