How to email MMS to phone?
I'm new to T-Mobile, but I've Googled this question and read to use my phone number with @tmomail.net as the address to send to my phone. Every time I try, it comes back with the 550 error. W...
I use Gmail. I was previously with AT&T, and created a contact called "My
Cell phone" with the email phonenumber@txt.att.net. This worked for years.
When I switched to T-Mobile, I changed the contact email to
phonenumber@tmomail.net.
This is where the problem started. Even though I changed the address, it
would not work. I've since deleted the contact and used
phonenumber@tmomail.net, and it works now. Thanks for the update.

carriers dont adjust to apps..the apps get adjusted to the carrier.
There is *definitely* an issue with T-Mobile where it comes to ‘tmomail.net’, @fireguy_6364 . I have been using this service to receive "on call" alerts for work issues for years. A couple of years ago, the reliability of tmomail.net messages started decreasing. At the time, I had a discussion with a VP of T-Mobile who works with the 'tmomail.net' product: it seems they've been having massive issues with SPAM, so they've tightened their SPAM rules more and more over the years.
I have periodically changed my alert message format, as well as the email provider with which I send the messages. Upon analyzing the failure messages I receive (in my junk mailbox hours after the message was sent), I usually can fix the issue (ie, ensure the message headers contain minimal SPAM signals). However, in the last few months, the messages have been failing with "server temporarily unavailable AUP#MSRT".
AUP stands for Acceptable Use Policy, which suggests my messages are once again being marked as SPAM by T-Mobile's services. Further, the failure messages are coming from 'tmo-west.mx.a.cloudfilter.net' - which is the company T-Mobile uses for SPAM filtering.
I use this service for a week every month, during which I am on call for work support. Work emails the messages to my mail account - usually a few messages per week from work, and one test message per day from myself to ensure my tmomail is working - so it's not a ton of messages. I use an app I wrote to send the 'tmomail.net' message from my current email account such that it is not "forwarded" (which is a SPAM signal) - it is a brand new message sent specifically from that account. AND, it's single messages, coming from my own mail account to my own phone - I'm not doing "business" or "mass marketing email" or anything of that genre. Yet, still...
As for mail services, I went from a couple of generic email services, to gmail, then to iCloud when gmail started getting blocked. All of them worked for a short time, after which 'cloudfilter' started blocking the messages. As I noted, the messages I get from iCloud account now say either the above, or occasionally that cloudfilter refused to talk with iCloud.com. And the failures are ALWAYS from 'tmo'-something at cloudfilter - so it’s definitely T-Mobile causing the problem.
