Custom Domain will now only send messages via iCloud/browser
On my Mac, if I select my custom domain name to send from, I get the error message:
"The server response was: <6.99.9.51.dyn.plus.net[51.9.99.6]>: Client host rejected: Access denied"
However, I can send via iCloud in Safari and my iPads are both happy to send from the custom domain. It's driving me nuts having to reach for another machine every time I want to send mail from that domain.
Any ideas?
Mac Studio, macOS 14.2
