System Requirements

Warning

To install iRedMail on OpenBSD, you need:

Note

Preparations

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 to view the current hostname:

$ hostname
mx.example.com

On OpenBSD, hostname is set in two files: /etc/myname and /etc/hosts.

mx.example.com
# 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
mx.example.com

Choose a nearest mirror site for installing binary packages

iRedMail will install all required binary packages with command pkg_add -i from mirror site defined in file /etc/installurl (FYI: installurl(5)), If no mirror defined, iRedMail will use the fastly CDN for package installation.

It's recommended to install packages from a mirror site, to reduce server load on OpenBSD primary servers. Also, installing package from a nearest mirror site will speed up package installation. You can find mirror list near you on OpenBSD web site: Getting OpenBSD.

Install required packages

iRedMail is wrote in Bash shell scripting language, so bash shell interpreter is required, install it first:

pkg_add bash dialog

Download the latest release of iRedMail

# cd /root/
# tar zxf iRedMail-x.y.z.tar.gz

Start iRedMail installer

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

Screenshots of installation

Note

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 in file iRedMail.tips.

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 automatically. Type y or Y and press Enter to start.

Important things you MUST know after installation

Warning

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.

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.
