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 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 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.

You know what? The hotspot data made me stop and think. If I'm going to pay more for less, I decided to search for people on Verizon that have the same problem that I'm trying to avoid… and I found them. There are users using phone@vtext.com (or whatever) to use email to text that are getting blocked but instead of cloudfilter.net, it's cloudmark.net (I think) that is bouncing back their emails. In fact I found a threads from consumers and business. The guy with the business said cloudmark has a form to submit to have his email domain whitelisted, but no one is responding to it. And he claimed there's no one at the cell carrier (Verizon) that even manages these things.

So it seems like there's no permanent way to avoid this issue… Really getting frustrated.

And Cloudfilter runs via Amazon web services, which, if you sign up and read their stuff about email filtering, it has a mechanism for creating a "verified identity" for an email address. It's a long shot, but I started trying to do that, but it made me think that maybe if I send from my email that is on my sprint account… maybe it would magically work? I don't know. I'm grasping at straws.

they own Cloudfilter.net

Finally talked to an engineer (Dan) that is familiar with the spam filtering they do. (I thought I commented this before here, but I don't see it, so... I learned that the domain sending the "sender rejected" error [cloudfilter.net] is owned by markmonitor.com, which is the company that must have been contracted out by T-Mobile to do spam filtering.)

Dan said that he was already familiar with this issue because he is handling the same exact issue for another customer. And apparently he doesn't have the capability of solving the issue directly. He created a ticket for the appropriate team to try and resolve the issue and said he would call me back.

I have 2 gmail accounts (one for my home automations that is blocked by markmonitor and one that I use as my primary email). I noted that if I send emails from my primary account, *sometimes* those messages get through and sometimes they're blocked. The other account however hasn't gotten a message through since 2 weeks ago and I checked that account for "sender rejected" error bouncebacks. I have 142 such bounceback errors. That's about 10-12 messages per day on average over the past 13 days (though I don't know if any of those bouncebacks are repeated - I don't think so - each one is maybe the 3rd bounce-backs in a series of temporary delays that ends in the "sender rejected" error).

Dan said that it could take 24 hours for the spam team to address my issue. I guess we'll find out...

Messages are again getting through.  It took a few hours after hanging up with Dan the other day for my messages to start coming though. Started getting messages that were sent within the past 2 days in random order.

Dan referred to the spam filtering company as "Cloudmark". He said he has access to a ticket system to create tickets about issues like this. He said that regular users don't have access to that ticketing system, but I did find this web form where you can submit a request to unblock an email address: https://www.cloudmark.com/en/contact.

Cloudmark responded to Dan's ticket saying that "users" had reported messages coming from my email account as spam, which is obviously bullshit since I only EVER send messages to myself. They lifted the block on the email address, which is why messages started coming through.

The problem is that it could start happening again and there are no magic words I can say to a tech support person that will get me to someone who knows what to do.

I also brought up the issue of randomly delayed messages. Dan said he would create a ticket with cloudmark to address that.

For any others hampered by the random delays of home automation messages sent via your phonenumber@tmomail.net, I have written an AppleScript that can send either SMS (if your phone is on your WiFi) or iMessage (if you're not on the same WiFi as the computer sending the text). The messages get through without the random delay caused by the spam filtering and I don't *think* it's subject to getting blocked.

The only problem is that it kind of defeats the purpose of wanting to send an SMS (if you don’t have a data signal), but I learned on Reddit that soon all calls and SMS messages will require a data connection anyway due to the decommissioning of the 2G network.

DM me if you'd like the script. I'll probably blog it eventually.
