Re: sending text to my cell phone using @tmomail.net no longer working?

AND GUESS WHAT… THIS IS NOW WORKING AGAIN !! I just successfully sent a Text to my tmo phone using GMAIL and it went thru ! Opening a ticket just to get my email account workingis not a good way to resolve a systemic problem. The issue is still present for me with Outlook and Gmail...using my business' Internet email servers works fine. This is a much bigger problem that T-Mobile needs to address. Personally as an Internet Engineer myself, I find it troublesome it's taking them this long to resolve the issue which started a month ago.16Visto4likes0ComentariosRe: sending text to my cell phone using @tmomail.net no longer working?
Actually I made a mistake with my dig command. I forgot to ask for the MX (mail exchange) record which is the email address of T-Mobile's systems: dig -t mx tmomail.net @8.8.8.8 ; <<>> DiG 9.18.12-0ubuntu0.22.04.2-Ubuntu <<>> -t mx tmomail.net @8.8.8.8 ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 27536 ;; flags: qr rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 512 ;; QUESTION SECTION: ;tmomail.net.

Despite repeated attempts to contact the recipient's email system it didn't respond. Contact the recipient by some other means (by phone, for example) and ask them to tell their email admin that it appears that their email system isn't accepting connection requests from your email system. Give them the error details shown below. It's likely that the recipient's email admin is the only one who can fix this problem. For more information and tips to fix this issue see this article: https://go.microsoft.com/fwlink/?LinkId=389361. Similar response from my gmail accountit...almost seems like an aggressive email filter is in place with T-mobile. You might want to update your ticket with this info.2Visto1like0ComentariosRe: sending text to my cell phone using @tmomail.net no longer working?
Looking at this more it would seem T-Mobiles email to sms server(s) have no IP information associated with the DNS record, so no way for mail servers to send to them. If it was working from some email clients that's because the DNS info probably hasn't yet aged out of their cache, but those clients will eventually stop working as well. This is why some clients are still working while others are not. This is basic Internet 101, it's a bit shocking no one at T-Mobile is aware of this issue! dig tmomail.net @ns10.tmobileus.com ; <<>> DiG 9.18.12-0ubuntu0.22.04.2-Ubuntu <<>> tmomail.net @ns10.tmobileus.com ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 60699 ;; flags: qr aa rd; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 1 ;; WARNING: recursion requested but not available ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 1232 ;; QUESTION SECTION: ;tmomail.net.

I use this service for texting security alerts from cameras. Does no one at T-Mobile monitor their email to SMS gateways?!? Service doesn't work from either my google or outlook accounts.20Visto1like0Comentarios
