The three strings that are the most certain never to be registered as TLDs are .corp, .home and .mail. https://features.icann.org/addressing-new-gtld-program-applications-corp-home-and-mail I use .corp merely because it's not a Common Word, and so grepping for it will hit the least number of false matches.
