How to Set Up iRedMail on Ubuntu Server

iRedMail automates the complex process of setting up a full mail server — it installs and configures Postfix, Dovecot, Roundcube webmail, Amavis anti-spam and a web-based admin panel.

Prerequisites

• Fresh Ubuntu 20.04 server
• Minimum 4GB RAM recommended
• FQDN hostname configured
• Ports 25, 80, 443, 465, 587, 993 open

Step 1 — Set Hostname

sudo hostnamectl set-hostname mail.yourdomain.com
echo "127.0.0.1 mail.yourdomain.com mail" | sudo tee -a /etc/hosts

Step 2 — Download iRedMail

cd /tmp
wget https://github.com/iredmail/iRedMail/archive/refs/tags/1.6.8.tar.gz
tar -xzf 1.6.8.tar.gz
cd iRedMail-1.6.8

Step 3 — Run Installer

sudo bash iRedMail.sh

The installer asks:

• Mail storage path: /var/vmail
• Web server: Nginx
• Database: MariaDB
• Your domain name
• Admin password
• Optional components: Roundcube, SOGo, iRedAdmin

Step 4 — Reboot

sudo reboot

Step 5 — Access Admin Panel

https://mail.yourdomain.com/iredadmin
# Default: [email protected] / your_password

Step 6 — Configure DNS

# iRedMail shows required DNS records after installation
# Check: /root/iRedMail.tips file
cat /root/iRedMail.tips

Step 7 — Verify Setup

# Check all services running
sudo systemctl status postfix dovecot nginx mariadb

# Test sending
echo "Test" | mail -s "iRedMail Test" [email protected]
