Let me run an idea past you all. How about an SPF parameter to indicate
that only permitted senders may relay messages? That is, nobody else
would be allowed to relay messages from the sender, period. (This is
not the same as "-all".)

SPF is already completely general with exists. The only way to make
it more powerful is to define more macros so that more variables are
available to the exists code.
Okay, how would you implement the feature with the current exists
mechanism?
We don't want to add any more shortcut mechanisms for receivers to
execute - because unless *every* receiver executes them the same way,
we have problems.
Doesn't the same problem occur if you introduce additional variables for
exists?
