Why is T-Mobile mail-to-SMS gateway sporadically blocking GMail?
I use the mail-to-SMS gateway to text me at different times of the day. For example, to alert me to do something on my to-do list, or to tell me if some long-running program on my PC, such as a backup, is completed.
Often the text comes through as expected. But, quite frequently, I get a message from GMail telling me that the email has been rejected , with a message similar to this:
421 4.1.0 <account@neurogami.com> sender rejected AUP#CDRBL
That email a via a custom domain that uses GMail to handle mail.
The curious thing is that this email (and a few others that are also custom domains with mail handled by GMail) is not really backlisted (as I think CDRBL suggests). Some messages from that account get through. In fact, Google will attempt re-delivery for quite some time if a message is rejected, and very often the mail does eventually get to me (albeit a day or two late).
My guess is that T-Mobile is rejecting messages relayed by one or another Google mail server, but not all of them. When a message is eventually resent via one of the servers T-Mobile seems to like, it gets though.
Meanwhile it sort of makes the mail-to-SMS gateway less than useful, as the idea of text messaging is that it’s fairly immediate.

If you don’t have a mac where you can run my applescript workaround to this problem, you have 2 options: tell the sprint/T-Mobile support people that they need to create a ticket with CloudMark to un-block the email address you’re sending from or switch carriers (which may be a faster fix than calling repeatedly until you get a TMo/Sprint support person who knows what CloudMark is).
Switching is not a real good option for me, so I'll complain. But the idea that every single person who has this issue has to request each and every sending address be white-listed is nuts. But even that doesn't solve all the issues.
Another data point, to show haw crappy CloudMark is: I created a new gmail address, one that can't possibly have been flagged for anything. I've been sending messages using this new account, and at first none were rejected, but they took hours, or days, to arrive. It's insane.
I just checked now for bounce messages, and now even this three-day-old address is getting blocked.
This goes way beyond spam filtering. This is just ineptitude.
To add insult to injury, this Website blocks me if I am using my self-hosted VPN. :) I have to disable it in order to get here and post. I think this is just another example of clueless "filtering"; my colo server must be in some "suspect" IP range so I just get blocked, absent any actual spamming behavior.
