After I sent this message, I realized you were talking about digitally
signing of messages sent by internal people, where I was referring
primarily to encrypting messages destined to external recipients. I agree
that you absolutely need to have some strong authentication in place if
you start digitally signing outgoing messages, though I still think this
can be effectively managed server-side, when combined with the necessary
precautions like SMTP/TLS.
