I'm convinced that there really is no safe way to communicate through emails. If the government puts enough pressure on other countries and email companies, they will get the info they want. I fail to see how we can direct a machine to mars, land it, drive the damn thing around the surface for over a year, get samples, analyze them yet when it comes to deciphering an email, they stand around it like a group of cavemen
Those that think it's safe, I guess keep using it...as for me, I'll keep trying to tie a note to my dog's leg and give him directions as to where to deliver it
