Email was not designed with privacy from net operators in mind, in a time where actual NSA programs would had been considered a bad horror fiction movie. It relies in sending in plain text your private mail, with little to none encryption for headers (for the content was added some encryption, hard to use, and almost not used at all), sending to whatever server the dns claim that could accept mail for you, and is pretty easy to send mail that appears to come from you. Reality has changed. Is needed something that is easily usable by everyone, that certifies that the message really comes from you, that prevents interceptions in the path and that is strongly encrypted. Maybe it don't need to be that way for everyday, public mail, but for the one that is meant to be private and authenticated.
