I've worked in IT for almost 45 years. I have spent the last 3 years working on security. Hillary's email server was protected by out of date commercial security with known holes, based on what I've read. Any foreign intelligence service with reasonably good hackers could get in, copy everything and get out without a trace. For part of the time, a subcontractor was backing up Hillary's server to the cloud. The possibility that Hillary was using the server as part of a pay to play scheme involving the Clinton Foundation only makes it much worse. At that point Hillary can be blackmailed with information stolen from the server.
