Since 10/02/2026 I have not been able to *send* email from my sbcglobal/yahoo/att email account. Error: "sending message content to the server failed." The server response was: Error sending message for delivery."
Connection Doctor shows green dots for everything. Sometimes iCloud messages will send, but never the yahoo messages.
I am able to receive all messages. I have had this sbcglobal account since 2000s, rather not lose it for nothing.
I have tried deleting the Key Chain, deleting the account, adding the account, calling ATT (worthless), and AI search. Nothing works.
