First problem - I added my mx records over a week ago and they still wont verify. They are correct. I have verified other domains, so I KNOW they are correct. What is the problem?

Second problem - I am trying to add a new user email, but it is sending a verification. It didnt arrive on the phone, and I am creating the email, so it shouldn't be going to the email. I am a bit confused as to how I confirm the new email (and annoyed I have to do it if I have already verified the domain).  Is it going to send a message to the phone? I cant use internet and phone at the same time. Any suugestions?
