How does the White House prevent Obama's emails from being forwarded?
DanHulton: I doubt they implement or worry about technology to absolutely prevent anything the president ever emails from ever leaving the office.  Copy + Paste into a new email solves that pretty cleanly.The issue however, is what if someone unknowingly or accidentally forwards something the president wrote?  There's easy-to-setup and use technology in pretty much all mail servers to check for and prevent that.(I'd find it super neat however, if there were a program that took all of the president's emails and inserted extra random spaces/punctuation/etc. so that if there WERE leaks, they'd be identifiable.)
