Ran across some possibly decent greylisting sources last night.
milter-greylist looks like a good, fast greylisting implementation. The main question there is whether I can make it fit into the right spot with respect to MIMEDefang. Also, libspf2 would be useful in tuning the greylist. Ought to look into that even if I want to implement a MIMEDefang-internal greylist.
