This tutorial will show you how to install the groupware iRedMail on a fresh installation of Debian Wheezy.
You should use a server with at least one gigabyte of memory, preferably even two. While the software doesn't use many resources when idling, it peaks very fast when under load. For example, during virus scans.
Important: Please do not try to install iRedMail on a system that's already in production. It's designed to be installed on a fresh installation and will override other MTAs when it finds them. Please be cautious and always have backups at hand.
For the course of this tutorial, we will assume that you are working as the administrative user. If you
want to use
sudo instead, then you will have to append it where necessary.
First, make sure that a fully qualified domain name is set by opening
/etc/hostname with your favorite text editor and replacing the value there with a FQDN:
Next, make sure that FQDN is the first value listed in
127.0.0.1 mail.example.com mail localhost localhost.localdomain
Verify that everything worked by issuing
hostname -f. The output should be:
The only dependency of iRedMail is
bzip2, install it with:
apt-get install bz2
Download and unpack the latest version from the official homepage:
wget https://bitbucket.org/zhb/iredmail/downloads/iRedMail-0.8.7.tar.bz2 tar -xf iRedMail-0.8.7.tar.bz2
Change the permissions of the script, and run the installer:
cd iRedMail-0.8.7/ chmod 700 iRedMail.sh ./iRedMail.sh
The installation script will update your package list, then ask you some questions:
/var/vmailis the default and perfectly fine.
MySQLis just fitting - if you want to integrate into, for example, an ActiveDirectory user base then you should choose
The installer will now prompt you about a file with sensitive information in it,
/root/iRedMail-0.8.7/config, make sure to properly set the file permissions when the installation is finished:
chmod 600 /root/iRedMail-0.8.7/config
At this point, the installation script installs a lot of packages. After it has finished, you will be asked about firewall rules:
< Question > Would you like to use firewall rules provided by iRedMail now? < Question > File: /etc/default/iptables, with SSHD port: 22. [Y|n]
These questions depend on your wants. For a sane ruleset to start with, you should go for
Y here. Next, you'll be prompted with all the necessary information to use iRedMail - after a reboot:
(Don't worry, the prompted information can be found in
/root/iRedMail-0.8.7/iRedMail.tip after the reboot.)
The webmail interface can now be accessed with your web browser at:
However, since iRedMail uses a certificate that's not issued by a legitimate certificate authority (CA), you will most likely get a security warning from your browser. If you would like to remove the security warning, then you will need to obtain a certificate from a trusted CA. Installing a different certificate requires both the certificate and the private key. Once uploaded to your server, these files can be copied to the proper location with the following commands:
cp /path/to/your/cert /etc/ssl/certs/iRedMail_CA.pem cp /path/to/your/key /etc/ssl/private/iRedMail.key
Then, restart everything that uses the cert/key:
service postfix restart service dovecot restart service apache2 restart
And now you have a all-in-one mail solution. Happy mailing!
