[Mimedefang] Can MD/SA combo detect no reverse ip?

[G. Roderick Singleton]

I have been watching my logs for the past few days and find that there
is a bunch o' spam that gets trough with SA scores of less than the 5
threshold I use and most of these don't resolve to a reverse address
that is authoritative. I would like to block these and if possible block
dns lamers.

SO can MS/SSA do this in a filter or do I have to build this into
sendmail?
