Then, don't use the "after 220 greeting" tests. They stop less than
one percent of the spambots. If I had known that in advance I would
probably not have added those tests.

It would be a mistake to include DNS lookups with postscreen_access_list,
because those lookups happen before postscreen examines the dynamic
whitelist. That would slow down all the clients that are already
on the dynamic whitelist.
