Can't Send mail via Thunderbird
I have a frontier.com account that uses Yahoo as its server. After changing to Windows 11 >_< I updated Thunderbird and now I can receive messages to my frontier.com address but I can't SEND any. Why? I get this error message over and over: "Sending of the message failed. An error occurred while sending mail. The mail server responded: Request failed; Mailbox unavailable. Please verify that your email address is correct in your account settings and try again."
