Yes, sorry, I should have said the Return-Path header. Or some new fancy
header that is always equal to the envelope from.

But if you want to drop connections from unwanted addresses as early
as possible - as you could do if there's a per-user sending IPv6-address
- you can actually use the envelope from for that, because you don't
really care if it is correct/authenticated.

(The point I tried to make is that I don't think per-user IPv6-addresses
would solve anyone's problem, but that if it did, they'd already have
the tools to solve it.)
