Throttled email error code 451 4.2.0
I use comcast email for my business and personal needs. My clients are getting bounced back or delivery incomplete messages with the error code 451 4.2.0 Throttled - https://postmaster.comcast.net/smtp-error-codes.php#RL000010
These clients have email me previously without any issues, and they are not sending large files or links.

YES is a big problem. All of my emails to our accountant are being returned.

Just heard from a friend who got the same error message. Comcast/Xfinity e-mail has been pretty wonky over the past week. Over several hours last week, Xfinity kept restoring to my inbox e-mails that I had deleted (and emptied my trash) in MacOS Mail.
