iRedMail: Full-Featured Mail Server With LDAP, Postfix, RoundCube, Dovecot, ClamAV, DKIM, SPF On CentOS 5.x

Last edited 03/31/2011 

iRedMail is a shell script that lets you quickly deploy a full-featured mail solution in less than 2 minutes on CentOS 5.x and Debian (Lenny) 5.0.1 (it supports both i386 and x86_64). Its object is to make a Linux mail server installation and configuration simple and easy to use. iRedMail supports both OpenLDAP and MySQL as backends for storing virtual domains and users.This tutorial shows how to use the OpenLDAP as the backend.

The mail server components:

Now the newest version of iredmail start to support Debian (Lenny) 5.0.1,you can check the  install guide



Preliminary Note

In this tutorial I use:

LDAP suffix: dc=example,dc=com
OpenLDAP admin account: cn=manager,dc=exmple,dc=com
Mail domain:
Mail delivery (mailboxes) path: /home/vmail/domains

These settings might differ for you, so you have to replace them where appropriate.



Install CentOS 5.x, I suggest to use the minimum install, make sure you don't install Apache, PHP and MySQL. You can remove them with yum if they are installed.

Yum is working, because the installation needs to use CentOS source packages.

DNS MX record setting is no problem.



Download the iRedMail script:

tar xjf iRedMail-0.7.1.tar.bz2

Run the script to install:

cd iRedMail-0.7.1

Welcome page:

Mail delivery (mailboxes) path, all emails should be stored in this directory.

iRedMail supports both OpenLDAP and MySQL as backends to store virtual domains and users. OpenLDAP is selected.

LDAP suffix, normally it's your domain name:

Set a password for the LDAP server admin. Admin account is defined in /etc/openldap/slapd.conf, normaily it's: cn=Manager,dc=example,dc=com

Set a password for the LDAP virtual domain admin's password. cn=vmailadmin,dc=example,dc=com is used to manage all virtual domains/users.

Add your first virtual domain:

Virtual domain administrator account for the first virtual domain. Default is 'postmaster'.
