Overview

The purpose of this module is to configure postfix. It allows you to specify two postfix configurations in hiera.

Version 2.x.x and above does not use two separated classes for server and satellige like it was done in 1.x.x versions. Instead hiera is used to overwrite configs. Version 2.x.x and above does not merge parameters in code anymore, instead hiera merge is used.

Usage

The all available options for classes and defines are documented in the header of the class/define files. See there for any details.

postfix configuration

To use, include the postfix class.

To set parameters in main.cf file, use hiera:

postfix::parameters: 
    bounce_size_limit:
      comments:
        - 'The maximal amount of original message text that is sent in a'
        - 'non-delivery notification'
      value: 50000
    header_size_limit:
      comments:
        - 'The maximal amount of memory in bytes for storing a message header.'
        - 'If a header is larger, the excess is discarded'
      value: 102400

if you do not like to have a comment you can also set:

postfix::parameters:
  bounce_size_limit: 50000
  header_size_limit: 102400

Do deactivate a parameter that has been set by default, use:

postfix::parameters:
  mydestination:
    deactivate: true

Pervices are hash merged in hiera.

To set services in master.cf file use:

To add a service in master.cf file use:

postfix::services:
  smtp:
    type: 'inet'
    priv: 'n'
    chroot: 'y'
    command: 'smtpd'
  rewrite:
    chroot: 'y'
    command: 'trivial-rewrite'

Services are hash merged in hiera and can be deacitvated and removed from hiera.

create lookup maps:

Simple lookup maps can be created using:

postfix::maps:
  regex_sender_canonical:
    type: 'regex'
    contents:
      - "/^(.*)@%{::fqdn}/      ${1}+%{::hostname}@internaldomain.cirrax.com"
  hash_rewrite_local_sender:
    type: 'hash'
    contents:
      - 'user1          user1@cirrax.com'
      - 'user2          user2@cirrax.com'

Maps are hash merged in hiera.

To use them use set the parameters in master.cf accordingly.
