Hi,
My home automation system sends me SMS messages using T-Mobile's tmomail.net email to SMS gateway. I have been using it successfully for a number of months, but recently, my messages have been blocked. I have included a sample rejection notice below. Does anyone know precisely why my messages are being blocked all of a sudden and how to get around this?
Thanks so much for your help.
