Email-to-SMS not working

For the past 3-4 months I, along with other IT folks at my place of work, are not receiving our email-to-sms alerts sent from our mail server.  I have scoured the internet looking for answers, emailed abuse_rbl@abuse-att.net as well as mobilityabuse@att.com, and performed my own testing.  I have not received any response from either of the above emails.  My testing reveals that sending the email-to-sms from a GMail account works without issue, however sending from our business email does not.  I receive no bounce back or rejection email.  It is like the email is lost into the oblivion.  Our email-to-sms alerts have worked for 20 years and sometime late 2023 they stopped being received.  Verizon customers receive the email-to-sms alerts, as well as T-Mobile users.  I have seen several people in these forums with the exact same issue on AT&T but none have posted what their path to resolution was.  Lastly I have tested sending to both the @txt.att.net and @mms.att.net addresses, neither are received.

I thought I would give an update.  We contacted our external mail relay to find out if there were bounce backs, because we were not receiving any via email.  They found some.  AT&T is rejecting our emails.  Now that I have a rejection response I can send that over to abuse_rbl and hopefully get this resolved.  Below is an example of the bounce back:

PROCESSED|encode|plaintext|FROM:sender_email|TO:mobile_number@txt.att.net|SUBJECT:Alert: Server is Up|


to=<mobile_number@txt.att.net>, relay=att-e2xms-east.mx.a.cloudfilter.net[]:25023, delay=12, delays=11/0/0.47/0.94, dsn=2.0.0, status=sent (250 2.0.0 <sender_email> sender rejected)
