About Zimbra Collaboration Suite (ZCS)

Zimbra Collaboration Suite, shortly ZCS, is an Open Source, free for personal use, collaborative software platform for email, calendaring, tasks and more. It is currently being developed and maintained by Zimbra, Inc. ZCS is completely extensible and secure for your Organization or customers. We can deploy ZCS either on premises or private and public clouds easily. Since, we have direct control over ZCS, the data is completely safe and secure. It provides Mobile-enabled browsers and mobile apps, so you can collaborate anywhere, from any device. ZCS will easily fit into your existing solutions and infrastructure and quickly add additional functionality via Open APIs. You can use ZCS in small, medium-size enterprises to very large organizations. In short, it supports any size of the organization all over the world.

ZCS comes in two flavours, Open Source edition(Free), and Network Edition(Paid). ZCS consists of client and server components, and a desktop client. Zimbra Desktop is a full-featured free desktop email client. The ZCS Web Client is a full-featured collaboration suite that supports email, group calendars, and document sharing using an Ajax web interface. ZCS can synchronize mail, contacts, and calendar items with open-source mail clients such as Evolution, and also with proprietary clients such as Microsoft Outlook and Apple Mail. Zimbra also provides native two-way sync to many mobile devices such as Nokia Eseries, BlackBerry, Windows Mobile, iPhone, Android etc..

Install Zimbra Collaboration Suite In Ubuntu

We already have posted article about ZCS installation and configuration CentOS 7. If you’re planning to deploy ZCS in any RPM based distros, check out the following link.

In this tutorial, we will see how to install Zimbra Collaboration Suite in Debian based systems, for example Ubuntu 14.04.

In my case, my testing system details are:

  • OS: Ubuntu 14.04 64bit
  • Zimbra Server’s FQDN: mail.unixmen.local
  • Zimbra Server’s IP address:
  • DNS Server’s IP address:

Recommended Hardware Requirements:

You need to have at least the following system requirements to deploy ZCS.

  • Intel/AMD 64-bit CPU 1.5 GHz
  • 8 GB or more RAM
  • 10GB Hdd
  • Additional disk space for mail storage
  • Fast Internet connection

Recommended Software Requirements:

  • Firewall should be disabled
  • RAID-5 is not recommended for installations with more than 100 accounts
  • RHEL/CentOS 7 64 bit
  • RHEL/CentOS 6 64 bit
  • Ubuntu 14.04/12.04 LTS 64 bit.
  • SUSE Linux Enterprise Server (SLES) 11, SP3 64-bit
  • VMware vSphere 4.x
  • VMware vSphere 5.x

Update your system and install the necessary dependencies for Zimbra:

First make sure your system and the packages are up to date.

sudo apt-get update && sudo apt-get upgrade

Then, install the following prerequisites:

sudo apt-get install libgmp-dev libidn11 wget nano make netcat sudo sysstat libtool libltdl7-dev build-essential libc6 perl ntp libperl-dev libidn11-dev sysstat sqlite3 wget libaio1 resolvconf unzip pax netcat-openbsd -y

Network Configuration:

sudo vi /etc/hosts

Add your Zimbra server’s IP address and hostname as shown below. Replace the following lines with your own values.   mail.unixmen.local      mail

Edit network configuration file:

sudo vi /etc/network/interfaces

Add nameserver IP address:


Then, edit:

sudo vi /etc/resolv.conf

Add your nameserver details.


Reboot your system once to take effect the saved changes.

Add DNS records in your DNS server:

Then, add proper ‘A’ record for your hostname and ‘MX’ record for your Domain in your DNS server.

If you don’t have DNS server, refer the following links.

Go to your DNS server. Then, add the ‘A’ record for your hostname and ‘MX’ record for your domain. In my case, I have a private DNS server in Ubuntu.

Note: Don’t use the same system for DNS server and Zimbra. It may conflict during installation.

So, I added the following lines in my DNS server’s forward and reverse zone files.

sudo vi /etc/bind/forward.unixmen

Add the following lines.

@                       IN  A
mail.unixmen.local.     A
mail.unixmen.local.     MX  0   mail.unixmen.local.
unixmen.local.          MX  0   mail.unixmen.local.

Add the same lines in your reverse zone file.

Then, restart bind9 service using command:

sudo service bind9 restart

Now, run the following commands to verify if our DNS records are working or not.

Go to your Zimbra server, and run:

nslookup mail.unixmen.local

Sample output:


Name:    mail.unixmen.local
dig mail.unixmen.local mx

Sample output:

; <<>> DiG 9.9.5-3ubuntu0.2-Ubuntu <<>> mail.unixmen.local mx
;; global options: +cmd

;; MSG SIZE  rcvd: 162

If your Ubuntu server is behind router/firewall, you should forward at least port 25 from your router/firewall to your Ubuntu server.

Great, now we have added the proper DNS records, and it’s working well.

Now, we will install Zimbra.

Download and install Zimbra Collaboration Suite:

Please note that deploy ZCS in freshly installed system. You cannot have any other web server, database, LDAP, or MTA server running, when you install the Zimbra software. If you have installed any of the applications before you install Zimbra software, disable these applications. During the Zimbra Collaboration installation, Zimbra makes global system changes that may break applications that are on your server.

Now, Go to ZCS open source download page and download the latest version depending upon your OS type. Here, we are deploying ZCS in Ubuntu 14.04 LTS,


Unpack ZCS using command:

tar xvfz zcs-*

Change to the extracted folder using command:

cd zcs-*

Now, start ZCS installer with the following command:

sudo ./

sudo rm -rf zcs-*


We, just, have covered the installation and basic configuration part. For complete details about installation and usage, I recommend you to have a look at the below links.


Installing and configuring Zimbra is like a piece of cake. ZCS installation is quite easy if you follow the above steps carefully. You don’t have to be a master In Linux. Everything will be automatically configured during ZCS installation. If you’re not satisfied with Open Source edition, purchase the enterprise version to have complete features and Zimbra professional support.

Give it a try, you won’t be disappointed.

Cheers! happy weekend!!
