You could run postgrey as a TCP service say "inet:" and 
have a single instance servicing multiple servers. If you insist on 
local instances, see sqlgrey which can talk to a remote database (over 
TCP/IP). There are a variety of policy servers available to suit/fit 
most requirements but as the MILTER_README states.. why re-invent the 
wheel.. The postfix devels also state that policy servers are the 
*preferred* way of doing things and milters are the next best option.

Anyways, the compatibility of MailScanner with Postfix (with milters 
enabled) is important and needs be addressed (whenever Julian has time).

Nerijus, Glenn had mentioned that you send some raw samples (where 
privacy is not critical) of mails pre and post milters to Julian.. did 
you manage to do that?
