Set up your own mail server like Hillary. It’s always with you and no one can turn it off except you or your power company. And no one other than you has access to it. That’s why Hillary had it.
Hilliary didn’t set up her own mail server. The tech she hired set it up with gmail underneath. So any snooper, governmental or private, could slip a few bucks to a goolag employee and get above top secret information, compartmentalized information, letter level information etc.
