How does the White House prevent Obama's emails from being forwarded?
mdasen: It's never impossible to forward an email.  Heck, you can simply take a screenshot and forward that along (or even write down the contents and re-type it).  A forwarded email is just as suspect as a screenshot that can be photoshopped.I think the way that they prevent it is that you'll get fired if you do it.  People who work in the White House are usually people who a) want the sitting president to do well and b) want a career path that will get them to even better things than they're at now.  A big Obama supporter isn't going to forward an email that might be embarrassing unless it's something like an order for human children to be served at a banquet.  Likewise, if you want to someday become a congressperson or become a big(er) deal in DC, you don't want to get a reputation as "that guy that spews everything you don't want public".So, really, you only need slight precautions to make sure that email isn't forwarded.  The kind of precautions that would let a hacker easily bypass it, but you wouldn't accidentally forward something.
