T-Mobile blocking incoming texts

I’m an embedded computer systems designer.  I have created a system based on Raspberry Pi that monitors certain aspects of a user’s home and sends a text to the user if certain conditions apply.  In testing it I have found that texting from that system to my T-Mobile phone fails.

I have turned on external texting (for want of a better phrase) by contacting Customer service.

I have demonstrated that the system works fine in sending email to other destinations than my phone, and I have demonstrated that I can send a text to my phone from gmail.  The problem, then, must be that even though I have loosened up security, T-Mobile seems to recognize and reject a text from msmtp in Linux.

How do we fix that?  Is there a way to turn on error messaging in T-Mobile texting?
