Unfortunately I am not a sendmail configuration expert
but I imagine that there might be trick to avoid calling
a milter filter on any arbitrary condition available
on macro level.

On the other hand it isn't very expensive to have
the milter-greylist always hooked in
and at the top of the RACL and DACL list
to have a whitelist statement
with the appropriate condition.
