Yeah; the point here is that if someone wants to change the
information of foo@example.com, you need to send mail to
foo@example.com asking for confirmation (ideally with some kind of
secret that only you and whoever reads foo@example.com would know; the
message-id would probably be enough.)

The game of science is, in principle, without end. He who decides one
day that scientific statements do not call for any further test, and
that they can be regarded as finally verified, retires from the game.
