Killing that spam with greylisting using Postfix and Postgrey

[porjo]

A couple of notes regarding the use of Postgrey on Centos 4 (RHEL4):

You can get the postgrey RPM from the DAG repository. Setup the DAG repository and use yum to install the postgrey package.

Update Postfix config as described in the parent post, then create /etc/sysconfig/postgrey and add the following to it:

OPTIONS="--inet=127.0.0.1:60000 --delay=60"

Then restart postfix and start postgrey:

service postfix restart
service postgrey start

On CentOS 5 I added the RPMForge thingamajig (it adds DAG's repository to your list)
This page also explains in a nutshell (remember that if the file in sysconfig doesn't exist, you must create it yourself): http://wiki.centos.org/HowTos/postgrey
From there, how to add RPMForge packages:

Also it had me install a plugin for yum...:
