Maybe you commented after the title changed? Original title was "How secure is your email? here's email-in-a-box" (at least that's what I remember it was).
My comment was basically "email is not secure." I think we agree on that point.
Yes. I guess I was just (badly) making the point that since it's impossible to just communicate with one server you control, a secure mail paradigm should include servers we do not control.
