Build A Free, Full-Featured Mail Server On Gentoo Linux With iRedMail

Summary

We're going to set up a free, full-featured mail server on Gentoo Linux, all mail service related components are free and open source, and you own all data. The installation process is extremly easy and smooth.

By following this tutorial, you will have below major software and services ready for production use:

 

Introduce iRedMail

Homepage of iRedMail project is here: http://www.iredmail.org/

iRedMail is:

With iRedMail, you can set up a full-featured, zero-cost mail server in less than 2 minutes. iRedMail works on 8 major Linux/BSD distributions:

 

System Requirements

WARNING: iRedMail is designed to deploy on a FRESH server system, which means your server does NOT have mail related components installed, e.g. Apache, MySQL, OpenLDAP, Postfix, Dovecot, Amavisd, etc. Otherwise it may override your existing files/configurations althought it will backup files before modifing, and it may be not working as expected.

To install iRedMail, you need:

NOTE: All packages are built and installed with the latest portage.

 

Preparations

Set A Fully Qualified Domain Name (FQDN) Hostname On Your Server

We need to set a FQDN hostname before setup mail server.

On Gentoo Linux, hostname is set in three files:

Short hostname: /etc/conf.d/hostname

# Part of file: /etc/conf.d/hostname
HOSTNAME='demo'

DNS domain name: /etc/conf.d/net

# Part of file: /etc/conf.d/net
dns_domain='iredmail.org'

Hostname <=> IP address mapping: /etc/hosts. WARNING: Please list the FQDN hostname as first item.

# Part of file: /etc/hosts
127.0.0.1   demo.iredmail.org demo localhost localhost.localdomain

Verify the FQDN hostname with command 'hostname -f'. If hostname wasn't changed, please reboot server to make it work.

$ hostname -f
demo.iredmail.org

 

Sync Portage, Build World And Install Necessary Tools

# emerge --sync
# emerge -uDN world
# revdep-rebuild
# emerge portage-utils
# etc-update

 

Download The Latest Release Of iRedMail

Visit Download page to get the latest release of iRedMail. At least iRedMail-0.8.0-beta2 is required.

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 directory /root/iRedMail-x.y.z.tar.bz2 (replace x.y.z by the actual version number).

Uncompress iRedMail tarball:

# cd /root/
# tar xjf iRedMail-x.y.z.tar.bz2

 

Start iRedMail Installer

It's now ready to start iRedMail installer, it will ask you some simple questions, that's all steps to setup a full-featured mail server.

# cd /root/iRedMail-x.y.z/
# bash iRedMail.sh
