Simplify: my "mailto: URI" had better be unique, or my mail won't reach me and I won't give a rat's whether it's identified, uniquely or otherwise. So: "G20010302T165500.0000Z!Superbiskit@Home.com" I am not, personally, concerned about those who wish to send mail without divulging their identity. If security of some message id is really a problem then put something like Message-ID: #SECURE# in the plain-text headers and bury the real ID inside the encryped part. Traffic like that should be moving through tunnels anyhow. > > > Wait... Gnus already does most of that.
