Sending email failed on account that has worked in the past
I am trying to send email from one of my 3 comcast accounts. This is one I have not used in a year or so, not since upgrade to Supernova. When I try to send a message from this little-used comcast account I get this failure note: "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."
My other 2 comcast accounts work just fine.
I have reviewed the account setting and can find nothing amiss. The only difference between the two good ones and the bad one is my name and the email address. The outgoing servers are the same <smtp.comcast.net>, the server names and types are the same: IMAP Mail Server, imap.comcast.net, the Ports are the same: 993, the connection security is the same: SSL/TLS, and the authentication is the same: Normal Password. And as far as I can tell I have not changed anything in this account since it worked well about a year ago.
What am I missing? Do you have any suggestions? I am unsure what the message means by "authenticating user."
Thank you.

Open Account Settings and select a Comcast account in the left pane, e.g. the one with [email protected]. Then click Edit SMTP server in the right pane. Is the User Name for the smtp [email protected] or something else? Repeat for other accounts and report which, if any, have a mismatch between the account address and the smtp User Name.
Thank you. Yes, on my non-working comcast account the user name had somehow changed and was showing the user name from one of the other accounts, the main comcast account. I'm guessing that in the conversion from the prior TBird version to Supernova that got somehow changed.
The curious problem I now have is that when viewing your message in TB when I click the green box that says "Mark it as solved" that used to bring me to the support page where I could write a note. Of late, when I click it, it just opens a blank screen in Firefox. The URL it goes to is this <https://support.mozilla.org/en-US/questions/1426438/solve/1608675?watch=bgMcbHqQbv&utm_campaign=questions-reply&utm_source=notification&utm_medium=email>
The URL of the page I am now on as I type this note to you is this <https://support.mozilla.org/en-US/questions/1426438>
I note that the URL I am on matches the first section of the non-working URL, but there is much added at the back end. Any thoughts on this issue? Not a biggie, but curious if it can be solved. Thanx again.
Make sure you have separate smtp servers for each account, and that each account uses the smtp with a matching User Name, even if all other smtp settings are identical:

Not sure about the URL you received. There is normally a long URL, such as the one for the 'Post a Reply' button in the notification I received in your last reply:
The forum software occasionally malfunctions. You can report it on the contributors forum:
So, the long URL you pasted in your last reply worked for me to get back here, but the long URL attached to the button, did not.
