  check_policy_service unix:postgrey/socket
in the smtpd_recipient_restrictions = line is all you need, and postfix 
will check on /var/spool/postfix/postgrey/socket

which is what postgrey will listen on.

Security is one reason, better load handling is another. There is a lot 
less resources required to setup and teardown a unix socket than a 
network socket.

I could, yes - but just wanted to make sure there wasent anything else 
in the mix  ( like the postgrey chap suddenly recommending everyone just 
use a unix socket )
