Mac mail stopped working

All 3 older Apple mac minis use the same mac mail, but one has stopped receiving or sending email.

The other 2 are OK.

Connection Doctor says: Connection status: Mail was able to connect to internet.

Then status says: "Could not connect to this comcast.net IMAP server."

Also, when I try to send email, error message says:

"The server 'smtp.comcast.net' cannot be contacted on the default ports."

Spent 2 days and 3 hours total with Comcast for help. I even deleted an address and put it back.

Any help will be greatly appreciated. Thank you.

What year model Mac Mini?

What macOS is it running?

I'm not sure about older macOS Mail versions, but I do know that macOS 10.13 w/Safari 13 and earlier versions, can no longer open Comcast Xfinity Stream.
