Install iRedMail on Debian or Ubuntu Linux
iRedMail is designed to be deployed on a FRESH server system, which means your server does NOT have mail related components installed, e.g. MySQL, OpenLDAP, Postfix, Dovecot, Amavisd, etc. iRedMail will install and configure them for you automatically. Otherwise it may override your existing files/configurations althought it will backup files before modifying, and it may not be working as expected.
To install iRedMail on Debian or Ubuntu Linux, you need:
- A FRESH. working Debian/Ubuntu Linux. Supported releases are listed on Download page.
- 2 GB of memory is recommended for a low traffic production server. Spam/Virus scanning will take most system resource.
- Make sure 3 UID/GID are not used by other user/group: 2000, 2001, 2002.
- All binary packages will be installed from Debian/Ubuntu official apt repositories.
- If you choose Ubuntu Linux, it’s recommended to use the latest Ubuntu LTS (Long Term Support) release for production use.
Set a fully qualified domain name (FQDN) hostname on your server
No matter your server is a testing machine or production server, it’s strongly recommended to set a fully qualified domain name (FQDN) hostname.
Enter command hostname -f to view the current hostname:
On Debian/Ubuntu Linux, hostname is set in two files: /etc/hostname and /etc/hosts .
- /etc/hostname. short hostname, not FQDN.
- /etc/hosts. static table lookup for hostnames. Warning. Please list the FQDN hostname as first item.
Verify the FQDN hostname. If it wasn’t changed after updating above two files, please reboot server to make it work.
Enable default official Debian/Ubuntu apt repositories
- iRedMail needs official Debian/Ubuntu apt repositories, please enable them in /etc/apt/sources.list .
- Install package bzip2 so that you can uncompress downloaded iRedMail package.

IREDMAIL_MIRROR=’http://126.96.36.199′ bash iRedMail.sh
Screenshots of installation:

- Choose backend used to store mail accounts. You can manage mail accounts with iRedAdmin, our web-based iRedMail admin panel.
There’s no big difference between available backends, so it’s strongly recommended to choose the one you’re familiar with for easier management and maintenance after installation.
- If you choose to store mail accounts in OpenLDAP, iRedMail installer will ask to set the LDAP suffix.
To MySQL/MariaDB/PostgreSQL users

- Set password of admin account of your first mail domain.
Note. This account is an admin account and a mail user. That means you can login to webmail and admin panel (iRedAdmin) with this account, login username is full email address.
- Choose optional components
After answered above questions, iRedMail installer will ask you to review and confirm to start installation. It will install and configure required packages automatically. Type y or Y and press Enter to start.
Important things you MUST know after installation
The weakest part of a mail server is user’s weak password. Spammers don’t want to hack your server, they just want to send spam from your server. Please ALWAYS ALWAYS ALWAYS force users to use a strong password.
Read file /root/iRedMail-x.y.z/iRedMail.tips first, it contains:
- URLs, usernames and passwords of web-based applications
- Location of mail service related software configuration files. You can also check this tutorial instead: Locations of configuration and log files of major components .
- Some other important and sensitive information
Access webmail and other web applications
After installation successfully completed, you can access web-based programs if you choose to install them. Replace your_server below by your real server hostname or IP address.
