Hi, Al,

That may be, but it would surprise me.   The carriers still get paid by virtue of charging the recipients for the SMSes, and in this particular case cutting off this line of communication is leaving money on the table, as email->SMS deliverability is desired yet optional/secondary functionality of the app.

Hi, Jaren,

There appears to be a misunderstanding.  The messages in question are in fact 1:1 interpersonal communication between my client's customers (the people who use my client's iPhone messaging app) and their correspondents (to whom we're trying to deliver via the email->SMS gateway).    We're not sending ads, newsletters, or other such cruft.


In any event, back to the original question:  I would really appreciate any contacts at Tmobile who can help me sort this out.  All of the Tmobile postmaster addresses I've tried have bounced.   I've posted on the developer web forum, but that forum is specifically geared toward people developing on Tmobile phones, which isn't us.
