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 GBof 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):
Make sure 3 UID/GID are not used by other user/group: 2000, 2001, 2002.
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:
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.
hostname to view the current hostname:
$ hostname mx.example.com
On OpenBSD, hostname is set in two files:
/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
it will check whether you have mirror site defined in
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
