SMTP Auth to *arbitrary remote domains' MX servers*? Am I missing
something, or are you?

You are. You should be doing SMTP Auth to *your* email server on which
you have an authorized account and then letting it relay your messages
to the world.

Ah; so then the End-To-End Principle is *not* The Prime Directive.

Good; thanks.  Can we stop flogging people with it who like DNAT, then?

Cheers
