    Email to SMS Problems

    meadowsvarsity2000

      I run a small Boy Scout Troop communication list.  I send out weekly email to sms reminders about activities.  Tmobile has blocked the email address I use.  I just got the following from sixteen (16) of my Tmobile users:

      The response from the remote server was:

      550 permanent failure for one or more recipients (x@tmomail.net:blocked)

       

      Final-Recipient: rfc822; x@tmomail.net

      Action: failed

      Status: 5.0.0

      Remote-MTA: dns; d79033a.ess.barracudanetworks.com. (64.235.153.10, the server
        for the domain tmomail.net.)
      Diagnostic-Code: smtp; 550 permanent failure for one or more recipients (x@tmomail.net:blocked)

      I checked with barracuda and they said I wasn't on their list, it must be on Tmobile's end

      How do I get unblocked?
