Cannot connect with smtp outbound server
Receiving msg "Sending of the message failed. An error occurred while sending mail. The mail server responded: Please ensure your email address and authenticating user match when sending messages. Please verify that your email address is correct in your account settings and try again."
This started yesterday. I have not changed settings or passwords. Up until a few moments ago, both my xfinity email addresses were affected. Now my primary can send but my secondary address still can't.
