---

✅ 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.
