Overview

The ssmtp module provides the installation procedure for SSMTP including the setup of the alternate system if not overwritten by class parameter.

Module Description

The SSMTP module prelace the standard mail server configuration with a light wight sending only server. The behavior is the same as sendmail but without the possibility to recieve mails from external systems.

Setup

What ssmtp affects

  • ssmtp package.

  • ssmtp configuration file.

  • ssmtp alternative service configuration.

Setup requirements

You need to activate the EPEL repository before you can setup the SSMTP instance. If you use a rpm based system from the RedHat family you can use my yum module (thbe-yum):

class { "::yum": repo_epel => true }

Beginning with ssmtp

include '::ssmtp' is enough to get you up and running if the parameters point to proper values. If you wish to pass in parameters like which servers to use then you can use:

class { '::ssmtp':
  mail_hub => 'mail.example.local',
}

Usage

All interaction with the ssmtp module can do be done through the main ssmtp class. This means you can simply toggle the options in the ssmtp class to get at the full functionality.

I just want SSMTP, what's the minimum I need?

include '::ssmtp'

I just want to route all mails to central mail gateway, nothing else.

class { '::ssmtp':
  mail_hub => 'mail.example.local',
  root_email => 'john.doe@example.local',
}
