Postfix + Postgrey on Debian

Because I found very LITTLE documentation on the web for this, here it is:

TASK: Install PostGrey (greylisting policy server for Postfix) on Debian
(Sarge, in this example)

You must have Postfix 2.1.x or better for this to work.

1) Install PostGrey (damn, thats easy, don't you love apt!?)
host:pwd# apt-get install postgrey

2) Verify the service is listed in /etc/init.d
host:pwd# ls -l /etc/init.d/postgrey

3) Add some domains that you want exempt from greylisting, if any
host:pwd# vi /etc/postgrey/whitelist_clients

4) Add the following to /etc/postfix/main.cf ::
# line for defining the policy server:
smtpd_policy_service_endpoint = inet:127.0.0.1:60000

# line for listing action upon RCPT command
smtpd_recipient_restrictions = permit_mynetworks, reject_unauth_destination,
check_policy_service inet:127.0.0.1:60000

5) Verify Operation... and... DONE!

Enjoy!
