I had an email account xxx@me.com: Can't access it : Used for security of my domain

Hi, I had an ??? @ me.com email account that was used as my security for my domain DNS etc. Now 123Reg say I must verify myself via the email they have sent to that address !! Catch 22 is now in progress.

Any idea how I might go about fixing, re-creating the email account so that I can verify myself :(
