Authentication required message
After I updated my Mac OS ... I can get receive emails in my Mac Mail but I can not send/reply.
It keeps telling me:
The sender address( my email here) was rejected by the server smtp.comcast.net.
The server response was: Authentication required
Select a different outgoing mail server from the list below or click Try Later to leave the message in your Outbox until it can be sent.
I have NO idea what that means or how to fix it.
Can someone help me with this?

Good morning! I am sorry to hear you are running into issues after an update. I want to check some basics first to ensure this is not the issue. Can you check if the third-party client access function is enabled. Please review steps in the link below to resolve your issue.
