That's a nice idea...but we can't even get all the open relay's closed.
How many years do you think it'll take to fundamentally change how the
SMTP protocol works across the entire internet?

I'm more in favor of the idea of using an SMTP server local to the network
you're dialing into and blocking or transparently redirecting SMTP traffic
to remote networks.  I realize this makes it difficult or impossible to
impose your restrictions on what your customers can do with SMTP if they
dial into outsourced ports, but IMO this would stop the abuse of open
relays much sooner than SMTP auth can.
