Getting back to the original point of the thread, why Google
apparently wants folks to specify "~all" rather than "-all", perhaps
in their case (because they offer a huge email service), they don't
wish to reveal all the possible outgoing SMTP servers to avoid some
type of attack on GMail.  Personally, I think there are better ways
of handling such things even in huge scale email service environments.

An interesting theory of yours, but I think if that was their motivation, 
they would have been bright enough to use an "exists:" mechanism to hide 
their infrastructure. :-)
