This may be the issue
Here are some details on this Government protocol implemented by all Telecom Carriers.
Why it is being done? To support FCC mandate for STIR/SHAKEN, an industry set of rules designed to authenticate and validate CallerID information associated with phone calls using digital signatures.
SHAKEN/STIR is a framework of interconnected standards. SHAKEN/STIR are acronyms for Signature-based Handling of Asserted Information Using tokens (SHAKEN) and the Secure Telephone Identity Revisited (STIR) standards.
What is the benefit to the clients being impacted (what do they get as a result)? Provide a means to mitigate/eliminate illegally spoofed calls from RoboCallers.

EXTERNAL EMAIL
FWIW, AT&T does not suggest using the
txt.att.net email for anything critical. In a previous role I handled public safety CAD, and AT&T (and Verizon, if I remember correctly) made it very clear that if you want to be able to send anything other than a miniscule volume of texts through the email-to-SMS
gateway, you would need to pay for their enterprise messaging service.
If the public safety agency/agencies in question subscribe to the FirstNet service, they should be able to reach out to their principal consultant (account team) and get a good
resolution.

txt.att.net outage?
Know this is a longshot, any chance anyone from the
txt.att.net domain might be able to help us with what we believe is a blacklist block or possibly an outage?
We deal with 911 cad dispatching and is affecting first responders so looking to see if there is a faster way to resolution.
Thanks, in advance.
