Description

Puppet module to manage your postfix installation. Manage main.cf settings and master.cf entries by postconf backed native types. Both types include support for multiple postfix instances. The postfix instances can be managed with a native type too.

Setup

Setup Requirements

This module requires pluginsync to be enabled to sync the type/provider to the agent.

Usage

The easiest way to use this module is to specify all desired configuration in Hiera. Here is a close-to-real-life example:

postfix::main_config:
  alias_database: hash:/etc/aliases
  alias_maps: hash:/etc/aliases
  append_dot_mydomain: no
  biff: no
  inet_protocols: all
  inet_interfaces: all
  mydestination: '$myhostname, localdomain, localhost'
  myorigin: '$mydomain'
  mynetworks:
    - '10.40.0.0/24'
    - '127.0.0.0/8'
    - '[::ffff:127.0.0.0]/104'
    - '[::1]/128'
  readme_directory: no
  recipient_delimiter: +
  smtpd_banner: '$myhostname ESMTP $mail_name'
  smtpd_relay_restrictions:
    - permit_mynetworks
    - permit_sasl_authenticated
    - defer_unauth_destination
  smtpd_use_tls: yes
  smtpd_tls_cert_file: &postfix_cert /etc/postfix/ssl/postfix.crt
  smtpd_tls_key_file: &postfix_key /etc/postfix/ssl/postfix.key
  smtpd_sasl_auth_enable: no # only enable for mandatory tls ports
  smtpd_sasl_type: dovecot
  smtpd_sasl_path: private/auth
  # sasl only encrypted
  smtpd_tls_auth_only: yes
  smtpd_tls_security_level: may
  virtual_transport: 'lmtp:unix:private/dovecot-lmtp'
  milter_protocol: 6
  common_milters: >-
    { inet:localhost:11332,
    connect_timeout=10s,
    default_action=accept }
  smtpd_milters: '$common_milters'
  non_smtpd_milters: '$common_milters'
  milter_mail_macros: i {mail_addr} {client_addr} {client_name} {auth_authen}

postfix::master_services:
  # merged with the defaults defined in data/modules/postfix.yaml
  smtps/inet: { ensure: present }
  submission/inet: { ensure: present }

This will create postconf and postconf_master resources for each setting. The resource types can also be used directly as described below.

Generating default master.cf entries

In order to generate the default postconf_master hiera entries needed to run postfix, you can use the provided master2hierayaml.rb script:

scripts/master2hierayaml.rb /usr/share/doc/postfix/defaults/master.cf > data/modules/postfix.yaml

It will try to parse active as well as commented entries and lines, and output warnings to stderr if it fails to do so. However, check the output carefully, otherwise you might end up with a non-working mail system.

Purging unmanaged entries

By default, this module will warn about unmanaged config entries in any managed main.cf and master.cf, but not remove them. To enable purging of those resources, set purge_main and purge_master to true:

postfix::purge_main: true
postfix::purge_master: true

Reference

Types

postconf

The postconf type enables you to set or rest postconf parameters.

  postconf { 'myhostname':
    value => 'foo.bar',
  }

The config_dir param allows you to manage different postfix instances and the parameter param allows you to define the postconf parameter independently from the resource name.

  postconf { 'myhostname':
    value => 'foo.bar',
  }

  postconf { 'foo:myhostname':
    parameter  => 'myhostname',
    config_dir => '/etc/postfix-foo',
    value      => 'foo.bar',
  }

postconf_master

The postconf_master type enables you to manage the master.cf entries.

  postconf_master { 'mytransport/unix':
    command => 'smtp',
  }

The config_dir param allows you to manage different postfix instances and the service and type param allows you to define the postconf_master service/type independently from the resource name.

  postconf_master { 'mytransport/unix':
    command => 'smtp',
  }

  postconf_master { 'foo:mytransport/unix':
    service    => 'mytransport',
    type       => 'unix',
    config_dir => '/etc/postfix-foo',
    command    => 'smtp',
  }

postmulti

The postmulti type allows you to create, de/activate and destroy postfix postmulti instances with pupppet.

By default ensure is set to active but can be set to inactive or absent respectively to deactivate or remove an postmulti instance.

As the postmulti the resource name must begin with postfix-.

  postmulti { 'postfix-out': }

Limitations

Known Issues

  • The postfix version of el7 does not support postconf_master. An alternative version is available from the IUS Community Project.
