Cannot send emails to myself using Apple Mail. Otherwise other addresses work fine.
Recently, using Apple Mail and Monterey OS, I've not been able to send emails to myself or my wife using @Cox.net. Emails to other servers work fine. There's no indication of a problem when sending the email but it never shows up on my Cox server.
So glad to see I'm not the only one with this problem. It happens every time I go to visit friends in Florida. The Cox mail works just fine, but the. Apple mail not at all. All outgoing messages get stuck in the out box.
