Unable to deliver email to comcast.net email addresses

Hi,

We have been unable to send to Comcast.net email addresses for over 14 days.

The message is:

[Edited: "Personal Information"] Throttled - try again later. Please see https://postmaster.comcast.net/smtp-error-codes.php#RL000003

Unfortunately, we are not throttled, we are blocked. I can clear the outbound queue and send just one email and it will never be sent and all we see is the above message. I've sent in multiple requests to unblock that IP to no avail. Our sender score is good and we're not on any blocklists. How can we get email moving to our Comcast.net customers again?
