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.

How to Pick the Best Linux Distro for Email Server: A Step-by-Step Guide
Here are some things to consider when picking the right Linux distro for your email server.
Level of Expertise
Obviously, the operating system running on your email server should be well-known. However, that is not enough to guarantee the effectiveness of your email server. You should also know some of the important features of emails and server administration. Otherwise, you will greatly complicate things.
An operating system’s design is important. Most people prefer a classic white interface with blue windows and office icons. If you have this type of interface, then it is easy to identify and find everything you want.
There are many different Linux distros for email servers. Each one of them has its own function, and they can all be used to produce a successful email server. So pick the right one that matches your needs.
The performance of a Linux distro is the key to its success. Without good performance, it is impossible to maintain good service levels and meet client needs.
Security is one of the most important factors when running an email server. It should come preinstalled with multiple security features. You should also install security updates frequently to ensure your server is always protected.
Linux Hardware Requirements
A good Linux distro for an email server requires good hardware configuration to work effectively. If the hardware is not high-end, it will struggle with multiple requests made simultaneously.
Ease of Installation
Installing the operating system on a server is always quite complicated. So you should pick a distro that has been designed to be easy to install. Otherwise, you may face many problems during the process.
Community or Commercial Support
Before installing the operating system on your email server, you should at least have a clear idea of who is going to support it in the future. This will reduce the risk of getting stuck with a bad support company.
Flexibility and Customizability
If you are going to be running an email server, then it is very likely that you will develop new features and customizations. So, being able to customize your Linux distro for email servers must be your highest priority.
