1 of 1 people found this helpfulThanks for your reply. I looked through those posts, but couldn't find an answer. I'm using gmail SMTP to send my email and Gmail seems fine with my authentication/authorization. When I look at the headers of the email, it passes SPF, DKIM, and the other checks mentioned in those posts. I'm not sure why my emails are being blocked all of a sudden and what the rules are that I need to follow for them to work successfully with the tmomail.net service. Thanks again for your help!

From what I read, it appeared that there was some learning/training to identify good/bad inbound messages. Since it's something on the backend, probably out of scope for a customer facing support portal. Did you try the enterprise support that was referenced? Wonder if any of the @tmo_ users can comment...

Hey, magenta2540820!
I'm not sure why it stopped all of the sudden, but as j.a.r.v.i.s mentioned, you aren't the only one this is happening to. I just chatted with one of our Engineers regarding this and here are a few things he recommended trying:
- If you're a DIGITS user, we recommend installing the app on your phone. Messages are successfully being sent and received through the app.
- If there's an option for the email to be sent via HTML format, it should force the email to stay as MMSC. I know this option isn't always available especially if it's coming from a larger company such as your home automation system.
If neither of these workarounds work, the next step would be to contact Tech Support and file a ticket with them. The more tickets that are filed, the easier it is for our Engineers to determine why this is happening.

Having same problem. Started last week.
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:
host d79033b.ess.barracudanetworks.com [64.235.150.252]
SMTP error from remote mail server after end of data:
550 permanent failure for one or more recipients (+1404xxxxxxx@tmomail.net:blocked)
I've had no problems for many years....except when sending a url. I have to remove http.

I am getting the same message as of last week and reported it to Tmobile support but they do not have an answer yet the very same barracuda network device is associated with Tmobile.
This is part of what I get back as being blocked.

Hey, is anybody here hearing anything concrete about what these "RATE LIMITS" are for sending to: TMOMAIL.NET ???
I'm sure that's the NUMBER ONE (1) REASON why MOST of us are here reading this Thread RIGHT NOW...
So MOST ALL of us,
1) NEED to get a certain email "unblocked" from our NUMBER@TMOMAIL.NET account
and also
2) NEED to KNOW what these RATE LIMITS are that got us "BANNED" in the FIRST PLACE.... It's PRETTY HARD to KNOW when they aren't posted up anywhere and it's literally almost TABOO to find any information at all on the Subject... it's really riddiculous: the Internet is supposed to stand for the EXACT OPPOSITE kind of thing...supposed to be a Wealth of KNOWLEDGE...Guess i'm WRONG on that....
CAN ANYBODY Help ??

My home automation system's messages suddenly stopped on January 23rd (day of last message).

Started failing for me two days back. But, I had not used it in a while, so I cannot say when the problem *would have* started for me. That said, all fail, to all tmomail.net addresses, from all email accounts/servers. Also, I tried plain text and html. Nothing in this thread is pointing in the right direction for issue I am seeing. Is it working for anyone? I am curious because I would like to use it, but have no huge need so I am not putting in a ticket. Thanks to anyone for any help .

PS: I can hit Verizon, AT&T, Sprint and even Tracfone people from my email today. So, it is not on my side.

I too started having the same issue. I have an extensive network system/home automation/live support system at home (IT guy here) and rely on getting security/power outage/system changes, etc notification via my TXT messages on my T-Mobile phone. I cannot stress how important it is that I don't miss any of them.
Well, yesterday I was configuring a new set of APC Smart UPSs with NMCs and email and text notifications were sent int the process. I tested notifications through management console and everything passed but I never got any messages. It wasn't until I checked my email that I noticed that except for the initial set, they were ALL rejected.
XXXXXX2XX6@tmomail.net

I have the same issue, and it started yesterday. I was able to send messages from my Gmail account, but now they come back as Error 550 - blocked. It's very frustrating as I like to send myself notes from my PC to my phone.

nocebeca, so sorry to hear that you're having issues with your tmomail.net messages! When you're sending out the messages, are they in plain text (without any HTML)? Also, it's definitely worth checking to see if you have a tmomail.net block placed on your line. You can reach out to 611, use the Message Us link on this page, or reach out to T-Force via Facebook or Twitter. I can't say as to why a block would suddenly appear there, but it's worth a check. If there isn't a block, you will need to have your rep file an engineering ticket. Let us know how it goes!
-
Thanks for the quick reply. I've already checked on my T-mo app on my phone, and there are no blocks. I knew that already as I regularly used to send myself notes. I sent my msg from Outlook in whatever format it is set to, but again that should not be the issue as I sending only reminders (text only). I will reach out to T-Mo if it the issue continues. Thanks again!

did you activated digits for the line to which you are trying to send email to text? I have observed that if digits if activated, it immediately starts blocking tmomail.net messages.
did you find any solution to this problem?

I am seeing this behavior as well. The irony is that I run a website that supplies rebates to T-Mobile Customers when they purchase new phones, and these customers are not getting their SMS confirmations because they are being blocked by T-Mobile's barracuda network dragons. I would appreciate knowing what magic incantations are needed to get past this blockage. An example message blockage looks like this:
2019-03-10 21:19:40 1h3CPb-000678-8Z ** {phonenumberdigits]@tmomail.net R=dkim_lookuphost T=dkim_remote_smtp H=d79033b.ess.barracudanetworks.com [209.222.82.141] X=TLSv1.2:ECDHE-RSA-AES256-GCM-SHA384:256 CV=yes: SMTP error from remote mail server after end of data: 550 permanent failure for one or more recipients ({phonenumberdigits}@tmomail.net:blocked)

Is there any solution to this? We host domain emails for a client that uses a program to send text reminders to her patients before their appointments. T-mobile is blocking.
How do we correct?
Here is an example (I've replaced the recipient phone number with x's and the sender email with y's) :
<XXXXXXXXX@tmomail.net>: host
d79033a.ess.barracudanetworks.com[209.222.82.159] said: 550 permanent
