iRedmail is one of the best open-source Mail server. With this you can deploy a full-featured mail server in few minutes. Even the newbie can easily able to understand the whole setup. Before the installation process lets have a glance about its features.
For CentOS minimal installation: https://www.linuxhelp.com/install-centos-6-5-snapshots/
Before installation you must have an static IP and a Fully Qualified Domain Name in your machine.
Here the following setup is done in my system.
Static IP : 192.168.5.87
FQDN : mail.dial4meat.com
For the configuration of static IP: https://www.linuxhelp.com/how-to-configure-static-ip-address-in-rhel/
Now we go for iRedmail Installation. Download the archive package from its official download page section and use wget command to download the latest version. The current stable version is iRedmail 0.9.4.
[root@linuxhelp ~]# wget https://bitbucket.org/zhb/iredmail/downloads/iRedMail-0.9.4.tar.bz2
In case if you cant reach the link from wget command just download directly in browser and then make use of it.
Next extract the downloaded tar package.
[root@linuxhelp ~]# tar xvjf iRedMail-0.9.4.tar.bz2
Now enter into the newly extracted iRedMail directory path and then make iRedMail.sh script to executable mode.
[root@linuxhelp ~]# cd iRedMail-0.9.4 [root@linuxhelp iRedMail-0.9.4 ~]# ls -l drwxr-xr-x. 2 501 games 4096 Apr 29 17:33 addons -rw-r--r--. 1 501 games 59799 Feb 4 18:48 ChangeLog drwxr-xr-x. 2 501 games 4096 Apr 29 17:33 conf -rw-r--r--. 1 root root 1837 Apr 29 17:49 config drwxr-xr-x. 2 501 games 4096 Apr 29 17:33 dialog -rw-r--r--. 1 501 games 318 Feb 4 18:48 Documentations drwxr-xr-x. 2 501 games 4096 Apr 29 17:33 functions -rw-r--r--. 1 501 games 4646 Feb 4 18:48 iRedMail.sh -rw-r--r--. 1 root root 6010 Apr 29 18:27 iRedMail.tips drwxr-xr-x. 4 501 games 4096 Apr 29 17:37 pkgs -rw-r--r--. 1 501 games 785 Feb 4 18:48 README.md drwxr-xr-x. 2 root root 4096 Apr 29 18:27 runtime drwxr-xr-x. 15 501 games 4096 Apr 29 18:27 samples drwxr-xr-x. 2 501 games 4096 Feb 14 15:52 tools [root@linuxhelp iRedMail-0.9.4 ~]# chmod +x iRedMail.sh [root@linuxhelp iRedMail-0.9.4 ~]# ls -l . . -rwxr-xr-x. 1 501 games 4646 Feb 4 18:48 iRedMail.sh . .
Before that some additional packages is to be installed. So go to "pkgs" directory and run the get_all.sh script. It will start checking the available packages for iRedmail. If it exists already then check for update.
[root@linuxhelp iRedMail-0.9.4/pkgs ~]# ./get_all.sh
Check whether the script is in executable mode or change using chmod command.
Once the process is done, continue with iRedmail installation.
[root@linuxhelp iRedMail-0.9.4 ~]# ./iRedMail.sh
The welcome screen will appear at first. Choose Yes to continue with installation or abort.
Next it employs the confirmation to store e-mails on /var/vmail system path, where it creates separated directories for every domain so that you can append it to your MTA server. If ok then continue or change the path to your need.
It will ask for the preferred web server such as nginx or apache. Choose the desired one using Space bar and click next
Now choose you preferred database to store mail domain names and the recipients that will connect to Postfix and then choose MySQL and then continue with Next.
Add your first virtual domain name and add only the domain name not system FQDN if you own a registered domain name.
The postmaster administrative account is used by the system to report incidents those related to mail functions, system failures, logwatchm which usually sends its statistics here - so select a strong password and continue Next.
Now choose your other mail server components like iRedAdmin official administrative panel to Postfix, DKIM domain keys, Roundcube default webmail interface, PhpMyadmin, Awstats and Fail2ban.
Depending on your optional components installed in your system you should answer with Yes. Pay more attention to iRedMail.tips file located on extracted directory since it contains sensitive mail server information such as usernames and passwords for server applications, server configurations files, default URL and other essential information.
Now reboot your system after installation completes and check iRedmail.tips file to see the server default settings.
Access the default web applications on the below URLs.
iRedAdmin administrative panel provides you with the basic web mail interface, where you can add virtual domains and also accounts for your mail server. To login to iRedAdmin panel you need to point your browser to
https://domain_name/iredadmin/ or https://server_IP/iredadmin/ URL and then use the following default credentials.
Password: postmaster password
This credentials can be verified with iRedmail.tips file located in the extracted directory.
iRedmail Admin Panel Home Page
To add a user navigate to Add -> User and provide your desired username and password. You are also allowed to setup the amount of space for your user Mailbox.
If the respective user is to make as Admin just check the Global admin check box.
Addition of Multiple Virtual domains
To add another virtual domain navigate to Add -> Domain and mention the desired domain name.
You can see the "Domain created" message. But confirm that "Enable this domain" box is checked. Incase if not checked then you cant access that domain.
Reading users email is provided by Roundcube web interface and in order to access it navigate to https://domain_name/mail or https://server_IP/mail/ and provide your mail account credentials in the form of firstname.lastname@example.org
Same credentials as we used for iRedmail admin panel login.
When you access the default administrative mail account postmaster you will see two initial emails, where one of them consisting of your servers sensitive information. And the another mail consists of other Useful resources.
Thus the iRedmail setup is completed. To compose mail click Compose in left top corner and Start with your content. Click Send to send the mail.
You can check your server’s open connections and listening daemon state by running the following command.
[root@linuxhelp ~]# netstat -tulpn Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 127.0.0.1:4190 0.0.0.0:* LISTEN 1497/dovecot tcp 0 0 127.0.0.1:7777 0.0.0.0:* LISTEN 1716/python . . . tcp 0 0 127.0.0.1:10026 0.0.0.0:* LISTEN 1517/amavisd (maste tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 1469/mysqld tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1300/sshd tcp 0 0 :::80 :::* LISTEN 1618/httpd udp 0 0 0.0.0.0:783 0.0.0.0:* 1221/portreserve
Logs for iRedmail setup will be stored by default in /var/log/maillog file.
[root@linuxhelp ~]# tailf /var/log/maillog
An important thing is that , after deploying a full mail environment, you need to have a valid domain name with a MX DNS record to receive mail from other domains such as Google, Hotmail etc.
