### How to Set Up iRedMail on the Latest Ubuntu Server (Step by Step Guide)

tutorials

Looking to run your own mail server? iRedMail is a powerful open-source solution for setting up a secure and full-featured mail system. In this guide, we’ll walk you through the process of installing iRedMail on the latest version of Ubuntu Server.

**✅ What You’ll Need Before Starting**

Before we dive in, make sure you’ve got the following:

-   A fresh Ubuntu Server (latest version) installed

-   Static IP address assigned to the server

-   A user with sudo privileges

### **🔄 Step 1: Update Your System**

Keeping your system up-to-date is a must before installing any major software. Run:

> sudo apt update && sudo apt upgrade

### **🌐 Step 2: Set Your Hostname**

Set the hostname to reflect your mail domain. For this tutorial, we’ll use mail.example.com.

> sudo hostnamectl set-hostname mail.example.com

Then update your /etc/hosts file:

> sudo nano /etc/hosts

Add this line (replace <IP-address> with your server’s actual IP):

> <IP-address> mail.example.com mail

Save and exit the file.

### **📦 Step 3: Download & Install iRedMail**

Get the latest version of iRedMail from GitHub:

> wget https://github.com/iredmail/iRedMail/archive/1.4.2.tar.gz

Extract the contents:

> tar -zxvf 1.4.2.tar.gz
>
> cd iRedMail-1.4.2

Make the installer executable:

> chmod +x iRedMail.sh

Run the installation script:

> sudo bash iRedMail.sh

Follow the interactive prompts to finish the setup.

### **🔧 Step 4: Final Mail Server Configuration**

Once installation is complete, head to your admin panel at:

> https://mail.example.com/iredadmin

Now, configure your DNS records (like MX, SPF, DKIM, and DMARC) and start adding your email domains and users.

### **🎯 Wrapping Up**

That’s it! You’ve now installed and configured a fully functional mail server with iRedMail on Ubuntu. You’re in control of your email data, security, and performance.
