Cox Email rejecting American Express Emails
How do I get Cox to stop rejecting emails from American Express?
I do not have any rules or filters set-up.
Here are the email addresses being rejected:
I had this problem with one of my Cox email accounts a few years ago, so I switched to another Cox email account now the second Cox email account is also rejecting these emails.
I've had the same problem with Capital One and Humana.
Who do I need to reach out to in order to fix this issue?
