Mail Version 13.0 not receiving or sending mail from any server.
My Mac Mail is not receiving or sending emails from yahoo, gmail, iCloud, any email account I have. This began last night, 4/17. No changes have been made to the account.
I've checked Preferences, Server and see nothing that indicates an issue. But all my email accounts are offline and will not reconnect.
