It's recommended to use the new iRedMail Easy deployment and support platform to deploy and keep your mail server up to date, technical support is available through the ticket system.
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.

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.
# cd /root/iRedMail-x.y.z/ # bash iRedMail.sh
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.
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
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.
After answered above questions, iRedMail installer will ask you to review and
confirm to start installation. It will install and configure required packages
Y and press
Enter to start.
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.
