This issue started occurring around the end of last week (5/12/22). Anytime a client or I try to send a specific link to a phone number (EX: 1234567890@tmomail.net) we receive the following error: 

“Google tried to deliver your message, but it was rejected by the server for the recipient domain <a href="http://tmomail.net" target="_blank">tmomail.net</a> by <a href="http://tmo-east.mx.a.cloudfilter.net" target="_blank">tmo-east.mx.a.cloudfilter.net</a>. [54.147.231.4]. The error that the other server returned was: 421 4.2.0 qhKynrJLCON26qhKznxskm internal error AUP#BL”

Is the link within the message breaking some kind of policy, or what exactly does the internal error mean?

My messages are compliant with the guidelines in that article you linked. I only send messages to myself. It's not spam. Yet my messages to myself are being blocked with the same error. This has been going on for nearly 2 weeks now. I have not received a single SMS from my home automations. Many of these SMS messages are mundane, but some are very important. We need more precise guidelines on how to use the email-to-text feature in a manner that will not result in our email addresses getting blocked and how to get an email address unblocked. If I was to send another person a message and it was blocked, they have no possible way of knowing that T-Mobile blocked a legitimate message. That is pretty heavy-handed. You should implement the equivalent of a spam folder so that users themselves can whitelist senders so that they can correct inappropriate spam flagging. The current system is unreasonable and unacceptable.

are you sending these links to your customers through your phone or from a computer to their phone?
