MacBook OS (Big Sur) Mail App stopped functioning
The Mail App on my MacBook has stopped functioning. The credentials have been verified on another device and the work fine. The credentials do not appear to even reach my mail server as I get no server error message as conformed by my Service Provider (SP). Further, if my credentials are wrong, the SP blocks my IP Address and requires manual intervention by the SP to unblock the IP Address. This has not occurred.
Has anyone else experienced problems like this?
MacBook Air 11″, macOS 11.7
