Thanks for the heads up, Scott.
I will say that your domain (and one of the other large ones) is absolutely notorious for spamming/blocking emails. The VA.com backend has been set up so that folks in your domain (and the other large one) will actually get two emails sent from two different mail service providers (one of which is Google). So, if neither message has shown up, your provider has blocked/spammed both messages. What is interesting is that there are other folks with your same domain that have received their registration keys without issue, and I do not have any outbound errors in the log for the last several days.
You *may* get your original emails in a day or two- which has happened before (and is totally weird). I've had something similar happen to me recently when trying to get emails from Roku while setting up a device (I use the other large mail service). I retried several times - I think I got one message some time later. Sorry to be blathering on about all that, but it's actually a real sore spot

On a positive note, I almost *never* get messages from Gmail users - and they are not set up to get two emails (the one they receive is not from the Google service). Not sure what Gmail is doing, but it works somehow.
Sorry about that. I hope you continue to enjoy the software!
