Cannot send text message to mms.att.net, only txt.att.net
We use a messenger application that allows for users to self-subscribe by sending a text to an email address. When the application picks up the registration email, it uses the person's @mms.att.net address. When we attempt to send a message to their @mms.att.net address, we get the "The email sent failed." message from no-reply@ address.
In order to correct this right now, we have to manually go into the database and change everyone's @mms.att.net address to txt.att.net. Since this is a dynamic service for our events, this is an unmanageable solution. All messages are sent from one email address, is there a way to get that email address whitelisted so our messages will get through?
