[Exim] smtp_accept_max_host && smtp_accept_reserve

Hi.

Is it possible to set up Exim so that it reserves $number of connections
for spesific hosts (using smtp_accept_reserver) and allow more than
$smtp_accept_max_per_host from just those hosts?

I would like to reserve quite a few connections to spesific machines,
which are allowed to relay mail through it, but not allow to aggressive
mailservers from the outside.
