I used my bellsouth email account for a very long time on my iMac. It got to a point that I could no longer send or receive mail. I could not fix the problem, so I decided to delete the account and reboot, and then add it back. Upon doing so, I got the message "unable to verify account name or password"; so I am stuck. The account name and password are correct, because I can access it in Safari by using the same credentials. How can this be fixed?
Maybe they've gone & done this like other providers with notifying users...

Yahoo App password…
Generate and manage third-party app passwords
Some older, third-party email apps (that do not use our Yahoo branded sign in page) require you to enter a single password for login credentials. To access your Yahoo Mail account on these apps, you'll need to generate and use an app password. An app password is a long, randomly generated code that gives a non-Yahoo app permission to access your Yahoo account. You’ll only need to provide this code once to sign in to your third-party email app.
