Overview

A module to configuring exim as a simple MTA to deliver all mail via a smarthost. It should be useful for any satellite system that needs to deliver mail via a central relay.

Module Description

This module will install Exim from EPEL and remove Postfix if it is installed (as installed by default on RHEL based distros). It will configure Exim to route all mail via the smarthost you define and qualify any unqualified mail names with the defined domain. Any mail destined for root will be sent to address defined in root parameter.

Setup

What eximsimple affects

• Exim package
• Postfix package (removes)
• Exim config (/etc/exim.conf)
• Aliases (/etc/aliases)
• Exim Service

Usage

  smarthost => 'smtp.mydomain.com',
  root      => '[email protected]',
  domain    => 'mydomain.com',
}
