I have just received an important email that I'd like to post online. However, I would like to know if there is some way of proving to the Internet that it is authentic (that the sender actually sent this message to me and I am not making it up). I am using Windows 7 and Windows Live Mail.
1Nope. You have the same problem with physical mail -- anyone can put the White House as the return address and put "Sincerely yours, Barack Obama" at the bottom of the letter. – David Schwartz – 2013-08-14T04:33:24.450
@DavidSchwartz They would also have to fake the letterhead and the President's signature (both of which are readily available online). – Lee Sleek – 2013-08-14T15:02:02.133
If those weren't available online, the recipient wouldn't know what they should look like anyway. – David Schwartz – 2013-08-14T18:30:54.803
