WARNING: 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 modifing, and it may be not working as expected.

To install iRedMail, you need:

  • A FRESH, working Ubuntu Linux. Supported releases are listed on page Features of iRedMail.
  • At least 1GB of memory is required for production use. if you have less memory, you have to disable spam/virus scanning by following our wiki tutorial. WARNING: It's strongly recommended to enable spam/virus scanning for production use, so please go get at least 1GB memory for your mail server.


  • All binary packages will be installed from Ubuntu official apt repositories.
  • 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

Enter command 'hostname -f' to view the current hostname:

$ hostname -f

On Ubuntu, hostname is set in two files:

  • /etc/hostname: hostname setting
# File: /etc/hostname
  • /etc/hosts: hostname <=> IP address mapping. Warning: List the FQDN hostname as first item.
# Part of file: /etc/hosts   mx.example.com demo localhost localhost.localdomain

Verify the FQDN hostname. If it wasn't changed, please reboot server to make it work.

$ hostname -f

Update apt repositories and install required packages

Run 'apt-get update' to update your apt repository info:

# sudo apt-get update

Install package 'bzip2' so that you can uncompress iRedMail installer.

# sudo apt-get install bzip2

Download the latest release of iRedMail

  • Visit Download page to get the latest release of iRedMail.
  • Upload iRedMail to your mail server via ftp or scp or whatever method you can use, login to the server to install iRedMail. We assume you uploaded it to directory /root/iRedMail-x.y.z.tar.bz2 (replace x.y.z by the actual version number).
  • Uncompress iRedMail tarball:
# cd /root/
# tar xjf iRedMail-x.y.z.tar.bz2

It's now ready to start iRedMail installer, it will ask you some simple questions, that's all steps to setup a full-featured mail server.

For Chinese users: Our domain name "iredmail.org" is blocked in China mainland since Jun 04, 2011, please replace all 'iredmail.org' by its IP address "" (without quotes) in /root/iRedMail-x.y.z/pkgs/get_all.sh BEFORE executing "iRedMail.sh". This is a Linode VPS hosted on Tokyo, Japan.
# cd /root/iRedMail-x.y.z/
# bash iRedMail.sh

7) Set password of admin account of your first mail domain. Note:

  • This account is used only for system administration, not a mail user. That means you CANNOT login to webmail with this account.

  • This account is a normal mail user, that means you can login to webmail with this account, login name is full email address.
  • Username is hard-coded, you can create new mail users with iRedAdmin after installation completed.
