# pkg install bash-static

Start iRedMail installer

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

# bash          # <- start bash shell, REQUIRED
# cd /root/iRedMail/

Screenshots of installation:


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

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


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.

Get technical support

Please post all issues, feedbacks, feature requests, suggestions in our online support forum, it's more responsible than you expected.

Some Tips for FreeBSD Jail

Allow ping in Jail

export jail_mx_example_com_parameters="allow.raw_sockets=1"

Share /usr/ports/distfiles with Jail

To share /usr/ports/distfiles/ with Jail, please append below line in /etc/fstab.mx_example_com:

Jail will set ports tree directory to /var/ports instead of /usr/ports in /jails/ by default, you can either use this default setting or change it to /usr/ports.

# Part of file: /etc/
/usr/ports/distfiles /jails/ nullfs rw 0 0

Create directory /usr/jails/basejail/var/ports/distfiles:

# mkdir /usr/jails/basejail/var/ports/distfiles
