there are enough writing their address uppercase while the server was never configured that way, there are enough writing FirstnameLastname@domain.tld and you can hardly find a normal person who accepts that writing a message to "YOU@domain.tld" goes to a different person than "you@domain.tld" or bounce in one of the cases
