Yes, but that limits inbound connections from *all* hosts,
not just for a particular host that connects more often than "on average".
With policyd, you could specify limits for specific IP addresses, if 
desired.  As I mentioned before, you can also do that with the "anvil" 
facility within postfix.  And a  big difference is that policyd will 
allow multiple SMTP servers to access a common DB.
