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

Remote-MTA: dns; d79033a.ess.barracudanetworks.com. (64.235.153.10, the server

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?
