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 modifying, and it may not be working as expected.
To install iRedMail on OpenBSD, you need:
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):
Note
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:
p5-Mail-SPF
, NOT p5-Mail-SPF-Query
Nginx is used as web 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
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 bzip2
Visit Download page to get the latest stable release of iRedMail.
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
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

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.
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:
After installation successfully completed, you can access web-based programs
if you choose to install them. Replace your_server
