Description

A Puppet module to install and manage OpenDKIM

Setup

What OpenDKIM affects

• install OpenDKIM package
• modify the configuration file /etc/opendkim.conf
• add and modify files in /etc/opendkim
• purge /etc/opendkim and /etc/dkim from all unuseful files

Warning : this package will replace all your RSA keys ! Before using it, be sure to add all your keys in Hiera !

Beginning with OpenDKIM

A basic example is as follows:

  class { '::opendkim':
    socket        => 'inet:[email protected]',
    trusted_hosts => ['::1','127.0.0.1','localhost'],
    keys          => [
        { 
            domain         => 'mydomain.com',
            selector       => 'default',
            publickey      => 'p=yourPublicKey',
            privatekey     => 'Your Private Key',
            signingdomains => ['*@mydomain.com', '*@subdomain.mydomain.com'],
        }
    ]
  }

Usage

You can also use natively Hiera :

  include ::opendkim

opendkim::socket: 'inet:[email protected]'
opendkim::trusted_hosts:
    - '::1'
    - '127.0.0.1'
    - 'localhost'
opendkim::keys:
    - domain: mydomain.com
      selector: default
      publickey: "p=yourPublicKey"
      privatekey: | 
        -----BEGIN RSA PRIVATE KEY-----
        Your Private Key
        -----END RSA PRIVATE KEY-----
      signingdomains: 
          - '*@mydomain.com'
          - '*@subdomain.mydomain.com'

If you want to use OpenDKIM though a UNIX socket with postfix for example, you should configure the socket like this :

opendkim::socket: 'local:/var/run/opendkim/opendkim.sock'
opendkim::umask: '0111'
