Install iRedMail on OpenBSD
[TOC]
System Requirements
IMPORTANT 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 althought it will backup files before modifing, and it may not be working as expected.
To install iRedMail on OpenBSD, you need:
-
A FRESH, working OpenBSD system. Supported releases are listed on Download page.
-
2 GB
of memory is recommended for a low traffic production server. Spam/Virus scanning will take most system resource. -
Required OpenBSD installation file sets are (replace
[XX]
by the real OpenBSD release number):- base[XX].tgz
- etc[XX].tgz
- comp[XX].tgz
- man[XX].tgz
- xbase[XX].tgz
Notes:
-
All binary packages will be installed with command
pkg_add -i
. It will prompt you to choose different versions of binary packages, please choose the one described below:- choose
p5-Mail-SPF
, NOTp5-Mail-SPF-Query
- choose
-
Nginx is used as web server.
-
PF is enabled by default, with basic rules for ssh and mail services.
-
System built-in
spamd(8)
is enabled by default for greylisting, whitelisting, blacklisting. -
OpenSMTPd are disabled by default, replaced by Postfix.
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
.
/etc/myname
: FQDN.
mx.example.com
/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
mx.example.com
Choose a nearest mirror site for installing binary packages
iRedMail will install all required binary packages with command pkg_add -i
,
it will check whether you have mirror site defined in PKG_PATH
environment
variable, if defined, pkg_add
will install packages from defined mirror site.
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.
Now login to the OpenBSD server as root user, set variable PKG_PATH
in file
/root/.profile
like below (use your nearest mirror site instead):
export PKG_PATH="http://ftp.jaist.ac.jp/pub/OpenBSD/`uname -r`/packages/`machine -a`/"
Install Bash shell, it's required by iRedMail.
# . /root/.profile # <- This steps is required, used to set PKG_PATH without re-login.
# pkg_add bash

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 it to
/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
Start iRedMail installer
For Chinese users: Our domain name "iredmail.org" is blocked in China mainland since Jun 04, 2011, please replace all 'iredmail.org' by its IP address "106.187.51.47" (without quotes) in /root/iRedMail-x.y.z/pkgs/get_all.sh BEFORE executing "iRedMail.sh". This is a Linode VPS hosted in Tokyo, Japan.
It's now ready to start iRedMail installer, it will ask you several simple questions, that's all steps to setup a full-featured mail server.
# 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.
IMPORTANT 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 you two questions about OpenLDAP.
LDAP suffix.
Password of LDAP root dn.
- Set password of MySQL or PostgreSQL admin user.
NOTE: MySQL is used to store data of other applications (e.g. Roundcube webmail, Cluebringer, Amavisd-new) if you choose OpenLDAP or MySQL as backend.
- 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 your confirm to
start installation. It will install and configure required packages
automatically. Type y

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.
-
Read file
/root/iRedMail-x.y.z/iRedMail.tips
first, it contains:- URLs, usernames and passwords of web-based applications
- Location of mail service related software configuration files. You can also check this tutorial instead: Locations of configuration and log files of mojor components.
- Some other important and sensitive information
-
It's highly recommended to purchase a SSL cert to avoid annonying warning message in web browser or mail clients when accessing mailbox via HTTPS/IMAPS/POP3/SMTPS. Or, you can use free SSL cert offerred by StartSSL.com. We have a document for you to use a bought 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.
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.
- Roundcube webmail: https://your_server/mail/
- Web admin panel (iRedAdmin): httpS://your_server/iredadmin/
- Awstats: httpS://your_server/awstats/awstats.pl?config=web (or ?config=smtp)
