README

+= Postfix Puppet module
+
+This module will help install and configure postfix.
+
+A couple of classes will preconfigure postfix for common needs.
+
+== Example:
+
   include postfix
 
   postfix::config { "relay_domains": value  => "localhost host.foo.com" }

manifests/classes/postfix-mailman.pp
