I've never seen .email in the wild or on a LAN. If it was for servers, wouldn't email-server.local, .lan, .home, .corp, etc. make more sense? And using it as a part of an address like [e-mail] seems redundant.

Emirates airlines use .email as their email only domain for booking emails, but their customer service center emails comes from Emirates.com
