I was going to remark that too, but is it going to cache negative
results? I would not say so. Then, what is the use of the cache since
most, if not all, genuine attempts, will happen when the primary is
down? In other words, how to populate the cache?
The solution would seem to have the secondary with the same priority
as the primary, but then one must be sure that they both use the same
antispam criteria, or it will be a bounce fest.
