iRedMail is out of the box open source mail server solution on Linux like operating system. The beauty of iRedMail is that it provides web based admin panel from where mail admin or system admins can do all email related operations task. Some of other features are listed below :
- Support unlimited email accounts.
- It provides Roundcube as webmail (MUA )
- It used Postfix as MTA & Dovecot as MDA
- It pvoides Calendar service via CalDAV & Contact service via CardDAV
- It uses SpamAssassin for Spam scan and Amavis & Clamav for Mail virus scan.
- OpenLDAP, MariaDB and PostgreSQL can be used to save mail accounts
In this article we will demonstrate how to install and configure iRedMail on CentOS 7 & RHEL 7. I am going to use followings for iRedMail setup.
- OS = CentOS 7 or RHEL 7
- Domain = nsitmail.com
- Server Hostname = mail.nsitmail.com
Note : In case if you want mails from your mail server to be delivered in inbox not in spam folder then update the DNS records like A & PTR before installation and TXT ( SPF & DKIM ) after installation.
Step:1 Set hostname and disable Selinux.
Set the proper hostname using hostnamectl command if it is not set.
[root@mail ~]# hostnamectl set-hostname mail.nsitmail.com [root@mail ~]# hostname -f mail.nsitmail.com [root@mail ~]#
Update the /etc/hosts file
127.0.0.1 mail.nsitmail.com localhost.localdomain localhost
Disable Selinux
[root@mail ~]# setenforce 0
Edit the file /etc/sysconfig/selinux , set the parameter “SELINUX=disabled” , Reboot the server to disable selinux completely.
Step:2 Download the tar file of iRedmail.
Download the latest version of iRedmail from their Official Web Site or use below wget command to download from terminal.
[root@mail ~]# wget https://bitbucket.org/zhb/iredmail/downloads/iRedMail-0.9.3.tar.bz2
Step:3 Extract the tar file & execute installation Script.
[root@mail ~]# ll total 124 -rw-r--r-- 1 root root 126277 Dec 20 19:12 iRedMail-0.9.3.tar.bz2 [root@mail ~]# [root@mail ~]# tar -jxvf iRedMail-0.9.3.tar.bz2 [root@mail ~]# cd iRedMail-0.9.3 [root@mail iRedMail-0.9.3]# sh iRedMail.sh
After couple of seconds , below screen will appear , Select yes and press enter.
Define the folder or directory where users mailbox will be stored.
Select the web Server for iRedmail. Default is Nginx.
Select the database of your choice which will store domain names and mail accounts. In my case i am using MariaDB.
Define the domain name for your mail server. In my case domain name is “nsitmail.com”
Set Password for postmaster account.
Select Optional Components of iRedmail installation
Press “y” to continue installation, Mail Server info & Credentials are kept in the file “/root/iRedMail-0.9.3/config”. Please keep this file in secure place.
As per instructions , reboot the server to enable all mail services.
Postfix mail logs and iRedmail logs are stored in “/var/log/maillog” and “/var/log/iredapd/iredapd.log” respectively.
Note : Default administrator name is “[email protected]”
Following are the Important URLs after the Installation is completed , replace the domain name as per your setup in mentioned URLs.
iRedAdmin – official web-based admin panel:
https://mail.nsitmail.com/iredadmin/
Username: [email protected], password: XXXXXXXXXX
Roundcube webmail URL :
http://mail.nsitmail.com/mail/
SOGo Groupware
https://mail.nsitmail.com/SOGo/
Step:4 Create Users & domain from Admin Panel.
To create users first login to admin panel. Use user name as “postmaster@<domain>” and password that we set during installation.
Click on Add option and then Select Users.
Add a new Domain :
From the admin Panel , Select “Domain & accounts” option and then click on Add domain
Define the domain name & Organization Name and then further we can create users on newly created domain.
Step:5 Access Roundcube (Webmail).
Open the url in the browser “https://mail.nsitmail.com/mail/” , replace the domain name as per your setup.
Send a test mail to verify the functionality.
As we see that i got the mail from iRedmail mail server, so we can say the iRedmail is successfully installed and configured.
Only thing missing is:
yum install bzip2 -y
Cheers!

Try accessing it with your Server’s IP address. In case you want to access it with hostname or DNS name , then you have to update your system hosts file with entries something like below
IP_Address_of_Server DNS_Or_Hostname
Hi,
Currently I have set the iredmail on local centos 7 server and its working fine. Now I have domain purchased. Now How can I configure the mail server for that domain. I have one static IP as well. But currently used that IP to different server.
Also let me know if any IP forwarding required for that as currently that is running on local centos 7 server. Please help me to configure.
Hi,
Add a Domain in your iredmail server from admin panel and assign the public IP address to your server and add a firewall rule in such a way that if any request comes on 25 port on your public IP it should redirect the request to server’s local ip.
From your Domain Panel, configure DNS records like A, PTR and MX.
after follow the process i got this one
This site can’t be reached
mail.musicout.com’s server DNS address could not be found.
Try running Network Diagnostics.
DNS_PROBE_FINISHED_NXDOMAIN
please help me
It seems like DNS records for your sever’s hostname ‘mail.musicout.com’ is configured properly. In your DNS server do A record entry of your mentioned hostname. In Case DNS server is not configured then do below entry in your system host file.
IP_Address_of_Server mail.musicout.com
I currently install the iredmail on the local centos 7 server and it works fine. Now I have acquired domain. How can I configure the mail server for that domain. I have a static IP and it also publishes.
I would also like to know how I could run it on the local centos 7 server. Please help me set it up.
Hi This was really useful . Thank you and I am planning to change my exchange server and use this as my mail server. Domain is active and I have the public IP configured . A firewall rule to point my exchange server is already there . So if I just create a same domain name and set the IP of my exchange server to this server, will everything work ..??
It should work, please make sure all users are created on the domain as well.
I install the iRedmail but cant access server/browser
Hi Sandeep,
– is your iredmail installation successful…?
– Update your server’s hostname either in DNS or /etc/hosts file.
– Also make sure https (443) port is allowed in OS firewall
