Sending e-mails with Postfix

In this recipe, we will set up Postfix Mail Transfer Agent (MTA). This will be a very basic setup which will enable us to send and receive e-mails from our server. Postfix is an open source MTA which routes e-mails to their destination. It is a default MTA for Ubuntu and is available in Ubuntu's main package repository.

Getting ready

You will need access to a root account or an account with sudo privileges.

A domain name (FQDN) is required while configuring Postfix. You can configure your local server for testing, but make sure that you set the proper host entries and hostname.

Follow these steps to send e-mails with Postfix:

  1. Install Postfix and mailutils with the following commands:
