The above is wrong.  
The postfix policy service only passes the envelope information
(client IP, HELO, MAIL FROM, RCPT TO) to the policy daemon (postgrey
in this instance), not the message itself, and expects a standard
postfix access table action in reply, such as DEFER, REJECT, DUNNO,
etc.  No queue is involved.  The postfix policy service is
postfix-specific and not likely useful with other MTAs unless/until
they specifically add support for this type of access map.

This is very different from amavisd-new which expects to receive the
entire message via SMTP from postfix.
