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 (firstname.lastname@example.org:blocked)
Final-Recipient: rfc822; email@example.com
Remote-MTA: dns; d79033a.ess.barracudanetworks.com. (22.214.171.124, the server for the domain tmomail.net.) Diagnostic-Code: smtp; 550 permanent failure for one or more recipients (firstname.lastname@example.org:blocked) Last-Attempt-Date: Tue, 11 Apr 2017 16:18:25 -0700 (PDT)
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?
E-mail to SMS is not considered very reliable. Is there a reason you use that rather than just e-mail?
14 - 15 year old kids don't check emails. Group Texts are annoying. It is a fast and easy way to remind kids/parents what is going on with the Scout group that day/week.
It should be reliable. It worked perfectly, until it was blocked by Tmobile. All of the other service providers work perfectly.
Have you tried sending the e-mails one-at-a-time? T-Mobile is pretty aggressive about blocking SPAM and your e-mail's might have been flagged as such. Also, T-Mobile used to market their E-Mail-to-text tools. They discontinued them and only left the e-mail-to-SMS system in place without much support.
Hey meadowsvarsity2000! I think email to messaging is definitely a creative way to get a kid's attention - we want you to be able to use it. Can you take a look at this thread: Text Message via Email and let me know if the suggestions from our engineer to force the message to convert to MMS are helpful?
Happy Sunday, meadowsvarsity2000! I just wanted to stop by and see if you'd had a chance to look over that link or test any of the suggested methods to force the message to deliver over MMS. How is everything going with your troop communications?
