Comcast rejecting email to/from accounts

Why is Comcast blocking email to and from USCG.MIL accounts? This has been happening for about a week now. I have entered a "ticket" but no resolution so far. Here is a copy of the error message a sender gets back:

A problem occurred during the delivery of this message to this e-mail address. Try sending this message again. If the problem continues, please contact your helpdesk.

The following organization rejected your message: [] is the Comcast server...

Re: Comcast rejecting email to/from accounts

I can't access or any other associated sites on my computer or phone either.  I turned wifi off on my phone and it immediately loaded but when I turned wifi back on, it wouldn't load again..  Hopefully this is resolved quickly.  I tried sending an email as well and received the following error:

"Message could not be sent. Error message from mail transport server: 452 - 452 4.1.1 ... temporary failure"

When I emailed through my gmail account I had no issues.
