Re: How to wish you hadn't forced ipv6 adoption (was "How to force rapid ipv6 adoption")

X.400 required a session key. IIRC you had to know the other side of the
mail exchange and do (weak, but of the time what we did) shared secret
swaps to bootstrap the protocol.

Of course, a cheat-sheet of 'your idea will not work because [ ]' kills it,
but I do recall with some fondness that in those days, basic hygiene
demanded you know who you sent mail to, and on whose behalf. For at least
some people.
