Postfix's anvil feature may meet the need. Its available in the CVS
snapshots. Some basic documentation is at

It allows you to say you will only take 1 email from an IP in a given
period of time, and you can whitelist and more.
What I'm looking for that would be even better is vthrottle added onto,
or something else that I just haven't found yet, that would have a sliding
window X and say that within X we will only take Y emails, and block if
its above that. Have X and Y be a generic setting and then the ability to
change them for a given netblock, so that AOL and other large providers do
not get hit by it.
But as it is, libmilter vthrottle looks like the best there is right now.
