The postgrey Portfile 51273 2009-05-22 03:50:32Z macsforever2000 macports.org $

PortSystem 1.0

Name: postgrey
Version: 1.32

Category: mail
Maintainers: sky.fr:cbellot
Description: Postfix policy server implementing greylisting
Long Description: When a request for delivery of a mail is received by Postfix via SMTP, the triplet CLIENT_IP / SENDER / RECIPIENT is built. If it is the first time that this triplet is seen, or if the triplet was first seen, less than 5 minutes ago, then the mail gets rejected with a temporary error. Hopefully spammers or viruses will not try again later, as it is however required per RFC.

Postgrey will be running with following default parameters:
user : postgrey
group : postgrey
tcp binding : localhost
tcp port : 60000

You will find configuration in ${prefix}/etc/postgrey
postgrey.conf : launch options
postgrey_whitelist_clients : default clients whitelist
postgrey_whitelist_clients.local : customisable clients whitelist
postgrey_whitelist_recipients : customisable recipients whitelist
postgrey_whitelist_recipients.default : default recipients whitelist (unused)

If you are using postfix, you should add to your main.cf a line:
check_policy_service inet:127.0.0.1:60000
in the smtpd_recipient_restrictions configuration (after
reject_unauth_destination and other rules) and reload postfix daemon.

If you haven't already installed Darwin Ports, you can find easy instructions for doing so at the main Darwin Ports page.
Once Darwin Ports has been installed, in a terminal window and while online, type the following and hit return:

%  cd /opt/local/bin/portslocation/dports/postgrey
%  sudo port install postgrey  
Password: 

You will then be prompted for your root password, which you should enter. You may have to wait for a few minutes while the software is retrieved from the network and installed for you. Y ou should see something that looks similar to:

--->  Fetching postgrey
--->  Verifying checksum for postgrey
--->  Extracting postgrey
--->  Configuring postgrey
--->  Building postgrey with target all

--->  Staging postgrey into destroot

--->  Installing postgrey

- Make sure that you do not close the terminal window while Darwin Ports is working. Once the software has been installed, you can find further information about using postgrey with these commands:

%  man postgrey
%  apropos postgrey
%  which postgrey
%  locate postgrey
