puppet-postfix

This is a temporary fork of thias/postfix which includes support for CentOS 7. This fork will be removed when the author responds to #40

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

  myhostname              => 'mx1.example.com',
  mydomain                => 'example.com',

  # 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)

  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',
  },
}
