Email to text not working

I have a website that sends an email to text my phone number at the AT&T SMS gateway The email is sent as This was working fine until just recently. Now the email fails, with part of the returned error message having Action: Failed and Status: 4.2.0.

I'm guessing that AT&T's SMS gateway suddenly doesn't like the domain that email is coming from. Any ideas on how to fix this?

Our company has been doing Email to text for 5 years and recently it stopped working.  So something happened on ATT side.  Any suggestions?

Maybe recently our company sender email address is getting blocked?
