421 4.2.0 sender rejected AUP#SNDR
I manage a few mail servers for my employer. We noticed that we are being blocked by T-Mobile (relay=tmo-east.mx.a.cloudfilter.net). We send a lot of messages to our customers' SMS gateway addresses daily.
As of today, all of our messages have started. On the servers we saw bouncing back with 421 sender rejected AUP#SNDR messages.
Is there any way you could whitelist our mail server IP addresses? I know you are making some changes to fight spam, but it is hurting our clients who want to get notified on new property listings.
I can email the logs to you at an appropriate email address or complete a whitelist form if you would like, along with a list of our mail server IP addresses.
Please assist us with this issue.
I also learned that with my current Sprint plan, I have 60G mobile hotspot data. I also learned that our current taxes in NJ total $2.26. Assuming the taxes will be roughly equivalent, that puts the 5G Start Unlimited plan at $112.26/mo for 2 lines.
That’s roughly $4.26 more per month with 55G less hotspot data.

So in preparation for making the switch to Verizon, I stopped by a T-Mobile store to drop off a Sprint Voice Pro device that they sent me awhile back to replace my Airave when my wife and I upgraded our phones (because they weren't compatible with the Airave anymore).
I brought up the issue of the email-to-text not working and the server bouncing back the emails with an error. The guy there confidently stated it was because of the Sprint network integration and said that migrating my account to T-Mobile would fix it. I couldn't remember at the time whether you ( @sdynak ) were already on TMo, but now I see you are when I review this thread.
So apparently the guy was bullshitting. Plus, they wouldn't take back the Voice Pro, but assured me that when I change providers, I'd be sent an RMA kit (though I'm really skeptical I won't get a whopper of a bill for it, given how discombobulated they all seem to be).
I did look at the magenta max plan though and it does appear to be cheaper than what I'm paying now. But if it won't solve this problem or the randomly slow texts or the choppy calls from inside our house even with WiFi calling enabled...
I am with T-Mobile and not from Sprint and on Magenta Max so it seems what he is telling you is BS.
And to add I have seen zero improvement since switching to Magenta Max. I was expecting priority service in crowded areas and nothing. I don't have anything other than my own experience and no actual data or facts. Just had issues with data in every crowded situation since I switched.

not a whole lot to block your signal out on the water as long as the antenna is pointed your way and youre close enough lol.
homes/businesses the signal gets to fight against mother nature plus every wire/piece of metal in your home

Hmmm… Yeah, the lack of a hotspot is somewhat of an issue. I rarely use it, but when I do, it's usually really important.
Exactly.. same here. How can I work from the boat without it 🤷🏻
does your phone have a signal when out on the boat?
Yes, I just boat in the Barnegat Bay in NJ.. there is actually better service where I typically go vs. my home believe it or not LOL.

So I just chatted with a Verizon sales rep. Sounds like if you already have FIOS (which I do), you get $5/line/mo off from whichever plan you select. So if I went with the "Start" plan which includes 5 gigs of mobile hotspot, it would be $55/mo with autopay and paperless billing and FIOS discount. That's the same as the welcome plan just with the hotspot added. So $110/mo + taxes (compared to $108 with taxes/fees with Sprint/T-Mobile). They said taxes depend on the state but they suggest expecting 10-15%. The upper end of that range would make my total (2-line) bill $126.50. It's less hotspot data than I currently get, but I'm hoping the calls will be less choppy and that their email-to-text feature actually works - and would experience shorter latency than I was getting with T-Mobile compared to when it *was* working (which could have occasionally been in excess of 24h since this past April).
Nice.. please, if you don't mind let me/us know how the e-mail texting works out and overall if you are happy once you get a good test drive. I don't have FIOS and it is not available to me. I can only get Verizon DSL which is a no go. I am stuck/cornered with Comcast/Xfinity. I understand they use Verizon so might be looking at that once the time comes.
