Re: NAT etc. (was: Spam Control Considered Harmful)

Yup, it could, but as I noted to Paul, in the cases Sean is advocating, the client and the NAT box may not be within the same span of administration, either. IE: no, you may _not_ trust the NAT op.

And as I noted in my reply, the real opportunities for NAT are when one side of the NAT trusts the NAT and the other side considers it "just another public client".
