Is there an example domain that has success receiving e-mail at iCloud+?

Even after following these instruction for my domain DSLWest.com absolutely no mail has ever landed in the iCloud account for user deecapp. We are now losing our domain because we can't do password recovery via e-mail.

Final goal: I’d like to keep DSLWest.com with OpenSRS registrar but want to move e-mail hosting to Apple/iCloud+ since this is just maintenance account. I’ve used the following instructions and you can see by the dig output below that it seems to be setup properly.

Ideas?
