Thanks! Can you elaborate a little more on the signing suggestion?

  PGP or GPG offer secure cryptographic signing of email. Taking a quick look at the GPG page we find some mentions of this: (http://www.gnupg.org/faq/GnuPG-FAQ.html#sec-8 http://www.gnupg.org/faq/GnuPG-FAQ.html#sec-8) ('Advanced topics'!) (http://www.dewinter.com/gnupg_howto/english/GPGMiniHowto-1.html#ss1.2 http://www.dewinter.com/gnupg_howto/english/GPGMiniHowto-1.h...) (mini how to in English, they have other languages available). (http://www.dewinter.com/gnupg_howto/english/GPGMiniHowto-5.html http://www.dewinter.com/gnupg_howto/english/GPGMiniHowto-5.h...) Signing and checking signatures. Just from these short snippets you can see that there is a lot of documentation for GPG; and that installing and using GPG[1] will be beyond most users. [1] Importantly it is crypto, and thus it's trivially easy for users to get this stuff wrong. Small mistakes do not necessarily mean anything visible to the user. The output could look real and useful, but actually be worthless.
