puppet-postfix

This is a puppet module for installing, configuring and managing the postfix message transfer agent.

Intent

The intention of this module is to provide a module that installs and configures postfix using a parametised class and augeas, rather than using custom template files. This included setting up appropriate rspec tests and smoke tests.

Postfix vs. Sendmail

There are many reasons to choose between sendmail and postfix, but in this case it was that the postfix configuration is a simple text file. The sendmail configuration has to be compiled, and this compilation step makes it difficult for Puppet to tell if a configuration change has been implemented, which in turn makes it difficult to create a module that is truly idempotent.

Default Usage

To install postfix with the default configuration:

include postfix

Configuration with Parameters

The postfix class is parametric and allows a single declaration to configure the postfix service. At this stage it only configures a few settings to allow the set up of a SMTP relay that forwards all messages to another SMTP host. The following example replicates the default configuration:

class {'postfix':
	remove_sendmail => false,
	myorigin			=>	undef,
	relayhost			=> undef,
	relayhost_port	=> undef,
}
	

Parameters

• remove_sendmail The sendmail service and packages will be removed from the system if this parameter is set to true. Default is false.
• myorigin This sets the default domain part of all outgoing email as per the postfix documentation. The default is undef, which will revert to the system default which is the local hostname.
• mydestination This sets the default domain part of all outgoing email as per the postfix documentation. The default is undef, which will revert to the system default which is $myhostname localhost.$mydomain localhost.
• relayhost This sets the FQDN of the host through which email will be relayed to the internet as per the postfix documentation. The default is undef, which reverts to the system default of attempting to send email directly out through the Internet.
• relayhost_port This sets the port for the relay host specified with the relayhost parameter. The default is undef which leaves the port specifier off the end of the relayhost setting. This parameter does nothing if the relayhost parameter is not set.
• daemon_directory Sets the directory with Postfix support programs and daemon programs are installed. The default is specific for each operating system. It's not recommended that this parameter be changed.
• inet_interfaces Sets the network interface for postfix to bind do. The default value is localhost
