This is absurd. Any responsible mail server will require some form of
control over the clients it allows to relay. If yours does not, please
see http://www.ordb.org/submit/ .
Yes, you might choose to allow unauthenticated relaying for clients in
netblocks under your direct control. But that is also reasonable, since
when you get an abuse report you can immediately cut off the relaying
It's a well-established best practice now to require SMTP AUTH for
relaying. Every mail server I have set up or currently administer is
exactly like what Steven describes. ISTM that the U. of Minnesota is
quite in the mainstream.

FWIW, I think it has been replaced. If I were to authenticate to send
through GMX, they would not allow me to use a different sender address.
Probably all major freemail providers, and many ISPs, are already doing

Everyone is (or should be, sigh) responsible for abuse that comes from

You'd simply have to create a new standard and get most server and
client software to implement it. Piece of cake. :)

Many talented people have worked tirelessly to find one, but alas,
there is no FUSSP in sight.
Offlist mail to this address is discarded unless
"/dev/rob0" or "not-spam" is in Subject: header
