puppet-postfix

Overview

This module is meant for Red Hat Enterprise Linux, its clones and FreeBSD. It still requires some major clean up, but is currently fully functional.

postfix::dbfile : Manage Postfix DB configuration files
postfix::file : Manage flat text Postfix configuration files
postfix::server : Manage the main Postfix instance

class { '::postfix::server':
  myhostname              => 'mx1.example.com',
  mydomain                => 'example.com',

  inet_interfaces         => 'all',
  message_size_limit      => '15360000', # 15MB

    'proxy:mysql:/etc/postfix/mysql_virtual_alias_domain_catchall_maps.cf',
  ],
  virtual_transport         => 'dovecot',
  # if you want dovecot to deliver user+foo@example.org to user@example.org,
  # uncomment this: (c.f. http://wiki2.dovecot.org/LDA/Postfix#Virtual_users)
  # dovecot_destination     => '${user}@${nexthop}',

    'permit_mynetworks',
    'reject_unknown_sender_domain',
  ],
  smtpd_recipient_restrictions => [
    'permit_sasl_authenticated',
    'permit_mynetworks',

  ],

  submission            => true,
  header_checks         => [
    '# Remove LAN (Webmail) headers',
    '/^Received: from .*\.example\.ici/ IGNORE',
    '# Sh*tlist',
    '/^From: .*@(example\.com|example\.net)/ REJECT Spam, go away',

  # Send all emails to spampd on 10026
  smtp_content_filter   => 'smtp:127.0.0.1:10026',
  # This is where we get emails back from spampd
  master_services       => [ '127.0.0.1:10027 inet n  -       n       -      20       smtpd'],
}

Parameters for main.cf

The most common parameters are supported as parameters to the postfix::server class, but any other ones may be added using the $extra_main_parameters hash parameter, to which keys are main.cf parameter names and values can be either a value string or array of strings.

Example :

class { '::postfix::server':
  extra_main_parameters => {
    'virtual_mailbox_lock' => [
      'fcntl',
      'dotlock',
    ],
    virtual_minimum_uid => '1000',
  },
}

Limitations

The service will only be reloaded on configuration change, meaning that changes requiring a full restart won't be applied, such as changes to listening interfaces.
