It's probably just a matter of perception, but I'd say the average user (and
we're not average users, remember) would understand (and be able to adjust)
more easily if the syntax looked something like this:

defer message = Try again later
  greylist = DEFER_IF_PERMIT

and have Exiscan worry about what parameters to pass over.

You'd need a config item which defined 'greylist' as a call to a Postfix
policy server on host:port or whatever.

NB: I know nothing about the internals of Exiscan (or Exim, for that
matter), so what I'm suggesting is quite likely very difficult to do..)
