Email to SMS via @tmomail.net Not Working

As of Sept 11 my alarm systems stopped sending me notifications via email to sms utilizing NUMBER@tmomail.net. After some troubleshooting we have concluded that the email system is failing:

 

Could not deliver message to the following recipient(s):

Failed Recipient: NUMBER@tmomail.net

Reason: Remote host said: 452 4.1.0 server temporarily unavailable AUP#MXRT

Is anyone else experiencing this issue? Any idea how to fix it? How to escalate it? We will be missing security/fire/medical alerts!

  • According to this answer, use of certain words in the message can trigger SPAM-filtering (which this looks like).

    In that answer, @HeavenM , Community Manager, says:

    … Are you sending these messages from your personal email address or from an automated email service? Does the email that you are sending from include words like admin, info, alert, test, contactus, or sales? (This is not a complete list of words in the email address that are filtered but gives you an idea.) The tmomail.net message route is not designed for ANY business messages …

     

    Also, this page defines “Consumer” vs “Non-Consumer” messages. It seems backwards, but “Consumer” messages are the ones people send to themselves or their friends, like right from your phone. “Non-Consumer” messages are the ones businesses send, such as when you get an authentication code from your bank or a reminder from your scouting organization, etc - anything that’s sending for a business or organizational purpose. “Non-Consumer” messages have to be set up with TMO or a messaging service.

    Beyond that, regular tmomail.net messages are supposed to work as long as they don’t meet the SPAM criteria.
