It is regularly alleged, on this mailing list, that NAT is bad *because it
violates the end-to-end principle of the Internet*, where each host is a
full-fledged host, able to connect to any other host to perform transactions.
We see it now alleged that the opposite is true: that a laptop, say, like
mine, which runs Linux and postfix, and does not require a smarthost to
deliver mail to a remote server *is a bad actor* *precisely because it does
that* (in attempting to send mail directly to a domain's MX server) *from
behind a NAT router*, and possibly different ones at different times.
I find these conflicting reports very conflicting. Either the end-to-end
principle *is* the Prime Directive... or it is *not*.
