BhumiTat - Re-engineering with innovations - Email Server and collaboration suite Ubuntu Zimbra

In this article, I will walk you through step by step process to setup you in-house email server. Hosting in-house requires that you set up and mange your own e-mail server, which gives you a little more flexibility and control. Since you are not paying for storage, you can make e-mail accounts as large as you want, add accounts easily, or host multiple domains. Since you are maintaining the server, you can control what kind of spam and virus protection you are running and make sure that the software stays up-to-date.

1. Install Ubuntu Server 20.04

Before starting the tutorial Install Zimbra on Ubuntu 20.04 in the installation , we have to create a domain for zimbra. For dns we use DNSmasq.

DNSmasq is a software that functions to store the IP of the sites that are accessed, in other words, a cache of the IPs of the sites that we access.

The advantages of using dnsmasq are

1. A simple configuration file is centralized in /etc/dnsmasq.conf
2. DNS Masquerade set-up is simpler to use as Local DNS compared to using BIND which has complex features
3. DNS Masquerade will read the /etc/hosts configuration as an A Record of each name server to be looked up
4. Simple

Catatan

1. IP Address = 172.20.2.90
2. Zimbra = Zimbra 8.8.15 GA Release
3. Domain = dixmata.com

Step 1: Update And Upgrade Linux (Install Zimbra Ubuntu 20.04)

First, for how to install Zimbra on Ubuntu 20.04, we have to update and upgrade packages on linux, so that everything needed to install Zimbra goes well.

apt update && apt upgrade 

Step 2: Edit Hostname And Linux Hosts File (Install Zimbra Ubuntu 20.04)

Edit Hostname and the Hosts file on Linux is located edit in /etc/hostname. Hostname is the name that will be used for our server. In addition, Hostname is also used for server identity.

nano /etc/hostname

Then fill in the domain you are using, here we use the example of mail.dixmata.com

Replace with the Domain name that will be used, then edit the hosts file with the following command:

nano /etc/hosts

And Reboot

reboot

Step 3: Install Dnsmasq

Next Install Zimbra Ubuntu, we will install dnsmasq as a DNS server. But before that we must first turn off systemd-resolve which is running on port 53, because DNS is also running on port 53 which causes the port to conflict.

systemctl disable systemd-resolved
systemctl stop systemd-resolved

Step 4: Configure Resolv File (Install Zimbra Ubuntu)

The basic configuration of the ubuntu resolv file is already linked with the ubuntu system, so to use dnsmasq we have to remove the link first.

To see if a file is still symlinked, use the following command:

ls -lh /etc/resolv.conf

Delete the resolv.conf file, follow the following command.

rm -f /etc/resolv.conf

Now create a new resolv.conf file and fill in the Google DNS server, follow the following command

nano /etc/resolv.conf

Install dnsmasq , follow the following command

apt install dnsmasq -y

Step 5: Configure Dnsmasq(Install Zimbra Ubuntu)

After installing Dnsmasq, then configuring Dnsmasq, open the dnsmasq.conf file located in /etc/dnsmasq.conf.

Backup the default dnsmasq configuration file, namely dnsmasq.conf, if there is an error in the configuration, we can restore it to the beginning. Follow these commands:

cp /etc/dnsmasq.conf /etc/dnsmasq.conf.bak

Edit file dnsmasq.conf

nano /etc/dnsmasq.conf

Follow the following configuration, changing ip-address and dixmata.com according to what you are using.

server= 172.20.2.90
domain=dixmata.com
mx-host= dixmata.com, mail.dixmata.com, 5
mx-host= mail.dixmata.com, mail.dixmata.com, 5
listen-address=127.0.0.1

Restart service dnsmasq

systemctl restart dnsmasq

Test A Record mail.

Dig for an A record of Zimbra Server.

dig A mail.dixmata.com

Continue with Test MX Record Domain

dig MX dixmata.com
