Hmm. milter-limit comes close, but I my reading of this is you want to 
limit number of RCPTs per message vs. overall messages over time. The 
former can easy be done as a new milter or milter-cli with a simple 
script to start counting RCPTs and start rejecting/temp.failing after N 
RCPTs per message appear.

The only problem is per-user or per-domain recipient configuration. Each 
RCPT is suppose to be a user on your server, yet how do you choose whose 
configuration to use? You might have several RCPTs with different 
configurations - how to choose: first seen, last seen, highest limit, 
lowest limit, or random selection, because you cannot apply them all; if 
you tried, you'd have problems with selection criteria.

The idea is interesting, but requires more specification I think.
