is your frontier SMTP server set to use authentication? Have you updated the SMTP server password to use an app password created using the Fonteir web site? Yahoo requires the use of oAuth, but as frontier has no oauth secret Thunderbird can not use it. You will probably need to create an app password for any of the connections to function going forward.
