[TOC]
If you want to install iRedMail inside FreeBSD Jail, please use this installation guide instead: Install iRedMail inside FreeBSD Jail (with ezjail)
System Requirements
!!! 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 although it will backup files before
modifying, and it may not be working as expected.
* Many ISPs block port 25 by default, it's used for communication between
mail servers, it must be open, otherwise your server may be not able to
receive or / and send emails. Please contact your ISP to make sure it's
not blocked, or ask them to unblock.
- Amazon AWS EC2. Request to [remove the throttle on port 25](https://aws.amazon.com/premiumsupport/knowledge-center/ec2-port-25-throttle/).
- Google Cloud Platform.
- Microsoft Azure.
- Linode. Explained in the [blog post](https://www.linode.com/blog/linode/a-new-policy-to-help-fight-spam/),
you can open a support ticket to request the Linode team to open it.
- DigitalOcean.
To install iRedMail on FreeBSD, you need:
- A FRESH, minimal, working FreeBSD system, no additional ports or binary packages were installed. Supported releases are listed on Download page.
- At least
2 GB
memory is required for a low traffic production mail server, but4 GB
is strongly recommended to prevent ClamAV eating too much memory for big virus signature database. - Make sure 3 UID/GID are not used by other user/group: 2000, 2001, 2002.
Note: All packages will be installed from ports tree.
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 -f
to view the current hostname:
# hostname -f
mx.example.com
On FreeBSD, hostname is set in two files: /etc/rc.conf
, /etc/hosts
.
/etc/rc.conf
: set hostname.
# Part of File: /etc/rc.conf
hostname="mx.example.com"
/etc/hosts
: hostname <=> IP address mapping.
# 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, please reboot server to make it work.
# hostname -f
mx.example.com
Update ports tree via portsnap
# portsnap fetch extract update
Install package bash-static
, it's required by iRedMail
# pkg install bash-static

(replace x.y.z by the real version number). -

# cd /root/iRedMail-x.y.z/
# bash iRedMail.sh
Screenshots of installation:
- Welcome and thanks for your use
- Specify location to store all mailboxes. Default is
/var/vmail/
.
- Choose backend used to store mail accounts. You can manage mail accounts with iRedAdmin, our web-based iRedMail admin panel.
!!! 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.
- If you choose to store mail accounts in OpenLDAP, iRedMail installer will ask to set the LDAP suffix.
!!! note "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`.
- Add your first mail domain name
- Set password of admin account of your first mail domain.
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.
- Choose optional components
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.

Read file
/root/iRedMail-x.y.z/iRedMail.tips
first, it contains:- URLs, usernames and passwords of web-based applications

Locations of configuration and log files of major components

It's highly recommended to get a SSL cert to avoid annonying warning message in web browser or mail clients when accessing mailbox via HTTPS/IMAPS/POP3/SMTPS. Let's Encrypt offers FREE SSL certificate. We have a document for you to use a SSL certificate.

If you need to bulk create mail users, check our document for OpenLDAP and MySQL/MariaDB/PostgreSQL.

If you're running a busy mail server, we have some suggestions for better performance.
