postfix_conf resource

Use the postfix_conf Chef InSpec audit resource to test the main configuration of the Postfix Mail Transfer Agent.

Availability

Installation

This resource is distributed with Chef InSpec and is automatically available for use.

Version

Syntax

A postfix_conf resource block declares the configuration settings to be tested:

describe postfix_conf do
  its('setting_name') { should cmp 'value' }
end

where

• 'setting_name' is a setting key defined in main.cf
• { should cmp 'value' } is the value to be expected

When using postfix_conf with a custom configuration directory, the following syntax can be used:

describe postfix_conf('path') do
  ...
end

where

• 'path' is the path to your Postfix configuration (ex. ‘/etc/path/to/postfix/main.cf’)

Properties

This resource supports any of the settings listed in the main.cf file as properties.

Examples

The following examples show how to use this Chef InSpec audit resource.

Test basic Postfix configuration settings in the main.cf file

For example, the following Postfix configuration:

/etc/postfix/main.cf:
	myorigin = $myhostname
	myhostname = host.local.domain
	mynetworks = 127.0.0.0/8

can be tested like this:

describe postfix_conf do
  its('myorigin') { should cmp '$myhostname' }
  its('myhostname') { should cmp 'host.local.domain' }
  its('mynetworks') { should cmp '127.0.0.0/8' }
end
