A Linux distro for an email server is a perfect operating system for a business or any other kind of organization. Using it effectively will require the right skills, knowledge, and expertise, however. So what is the right distro for the job?

When deciding the best distro for the server, you need to consider its cost, performance, stability, features, as well as the size of your organization. In addition, there are third-party applications to evaluate and consider.

In this article, we will try to address that question by presenting a list of the nine best Linux distros for email servers. Our choices are based on the following criteria: installation, ease of use, security, reliability, stability, and affordability.

1. Ubuntu Server

Ubuntu server desktop Linux
Ubuntu is officially released in three editions: Desktop, Server, and Core.

Mark Shuttleworth created Ubuntu Linux on 20th October 2004. It’s also called “distribution” because it comes ready to use and features the latest software. Ubuntu Linux is best for those who have limited technical skills.
