Zimbra, an open source mail server is not just to send and receive emails but it’s a fully featured collaboration suite which includes calendar, tasks, file-sharing, IM, mobile support and many more… Now, I wanted to deploy an email server on my work place and went through some research based on cost-effective, features, stability and easy to manage. And, I ended up choosing Zimbra open-source edition where as, I don’t need to worry about licensing. But the only thing to care about is hardware, power and internet. Zimbra also provide premium services which is cheaper compared to other e-mail solutions. Still this implementation is under testing. But, I really wanted to share what exactly I did on testing this product.
In this tutorial I will explain on how to setup Zimbra CS in Ubuntu 10.04 LTS. Make sure following requirements are met before you proceed with this.
- A domain name (e.g.: geeklk.com) with the ability to manage DNS and MX records. Assume I use geekdomain.com
- A PC installed Ubuntu 10.04 LTS x64 (64bit). I use Desktop Edition. Please refer System requirements document. Assume it has a Private IP 192.168.1.50
- Router is connected to the internet with a Static IP address, If you don’t have one, then refer this.
- Zimbra insallation file.
Configure your router to forward following ports to 192.168.1.50
22, 25 – SMTP, 80 – HTTP, 110 – POP3, 143 – IMAP, 443 – HTTPS, 993 – IMAP SSL, 995 – POP3 SSL.
We need to change host files to match the domain.
sudo cp hosts hosts.bak #Its good to backup configuration files if anything goes wrong
sudo nano hosts
192.168.1.50 mail.geekdomain.com zimbraserver
sudo cp resolv.conf resolv.conf.bak
sudo nano resolv.conf
Install Webmin and BIND dns server
Webmin is a web based tool to easily manage Ubuntu server
We need to create an internal DNS server. If you want to know why check this.
sudo apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl apt-show-versions libapt-pkg-perl
sudo dpkg -i libmd5-perl_2.03-1_all.deb
sudo dpkg -i webmin_1.580_all.deb
sudo apt-get install bind9
#reboot the system
After rebooting the server login to webming by https://192.168.1.50:10000 and login with ubuntu username and password. Do the following to set the DNS records.
Click Refresh Modules
Servers > BIND DNS SERVER > Forwarding and Transfers > Servers to forward queries to 126.96.36.199, 188.8.131.52
#Create master zone for geekdomain.com
Servers > BIND DNS SERVER > Create master zone > Zone type = Forward, Domain name / Network = geekdomain.com, Email address = email@example.com
#Create reverse zone for geekdomain.com
Servers > BIND DNS SERVER > Create master zone > Zone type = Reverse, Domain name / Network = 192.168.1.100, Email address = firstname.lastname@example.org
#Create A records for geekdomain.com
Servers > BIND DNS SERVER > irfad.me > Address > Name = mail, Address = 192.168.1.100
Servers > BIND DNS SERVER > irfad.me > Address > Name = geekdomain.com, Address = 192.168.1.100
#Add MX records for irfad.me
Servers > BIND DNS SERVER > irfad.me > Mail Server > Name = geekdomain.com, Mail Server = mail.geekdomain.com, Priority = 10
Stop BIND > Start BIND
Now the DNS server is set. To check DNS server works try these commands. Make the changes similar to this in the domain in public pointing to the ip address of the router’s internet facing interface (public IP)
dig geekdomain.com mx
Before installing Zimbra install the following packages
Now let’s install zimbra (the installation package is extracted on desktop)
cd /(zimbra 7 folder)

System will be modified? = Y
Change domain name = Y = geekdomain.com
4 = Admin password set = ******
r for previous menu
a to apply
Save config = Y and Enter
