Pull Requests gladly accepted How to Set Up DKIM (DomainKeys Identified Mail) with Postfix on Ubuntu 12.04

Introduction

In the ongoing effort to combat spam, DomainKeys Identified Mail (DKIM) has risen as a popular method for email authentication. DKIM associates a particular domain name with an email message. The need for key-based authentication arose because spam often has forged headers.

Prerequisite

This article assumes that you have completed the steps outlined in How To Install and Setup Postfix on Ubuntu 12.04 | DigitalOcean.

  1. Select Internet Site.
  2. Add all domain name

Server Setup

Follow the steps outlined in Setting the Hostname & Fully Qualified Domain Name (FQDN) on Ubuntu 12.04 or CentOS 6.4 | GitHub.

Then, open a terminal and update the local package index on your server with the latest changes made in the software repositories and upgrade the software packages already installed on your system:

sudo apt-get update && sudo apt-get -y upgrade && sudo apt-get -y dist-upgrade && sudo apt-get -y autoremove

The configuration outlined in this tutorial will rely on OpenDKIM, an open source implementation of the DKIM sender authentication system.

Installation

To install OpenDKIM, execute:

sudo apt-get -y install opendkim opendkim-tools
