sending text to my cell phone using @tmomail.net no longer working?

I'm having the same issue.  I only have the phone to get MMS alerts from our alarm system.  If they can't fix soon this I'll be shopping for a new carrier.

The alarm sends through a gmail account,  when I send an Email with the same attachment via my swbell Email account I get the MMS text on my phone.  I know the gmail account is sending the message because I have it bcc another Email account.

Hey id10ts at T-Mobile add a white list that we can edit for the Email to MMS gateway.  I assume after some number of similar messages they block the sender as spam.  STUPID!
