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:
2 GBof memory is recommended for a low traffic production server. Spam/Virus scanning will take most system resource.
No matter your server is a testing machine or production server, it's strongly recommended to set a fully qualified domain name (FQDN) hostname.
hostname -f to view the current hostname:
$ hostname -f mx.example.com
On Debian/Ubuntu Linux, hostname is set in two files:
/etc/hostname: short hostname, not FQDN.
/etc/hosts: static table lookup for hostnames. Warning: Please list the FQDN hostname as first item.
# Part of file: /etc/hosts 127.0.0.1 mx.example.com mx localhost localhost.localdomain
Verify the FQDN hostname. If it wasn't changed after updating above two files, please reboot server to make it work.
$ hostname -f mx.example.com
bzip2so that you can uncompress downloaded iRedMail package.
# sudo apt-get install bzip2

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
/root/iRedMail-x.y.z.tar.bz2 (replace x.y.z by the real 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 several simple questions, that's all required to setup a full-featured mail server.

To MySQL/MariaDB/PostgreSQL users
If you choose to store mail accounts in MySQL/MariaDB/PostgreSQL, iRedMail
installer will generate a random, strong password for you. You can find it
