How to setup Open Source Zimbra mail server in Ubuntu Server 20.4 LTS
Mainly Zima system have some requirements. but if you are trying to install it on a virtual emulation or eve-ng/pnetlab then no need to follow their official requirements. just folow the below steps.
1. Need a Domain name: I have mail.shaharul.abc
2. Need Domain name record in DNS server
| Type | Host | Value |
| A | 192.168.9.91 | |
| MX | @ | mail.shaharul.abc 91 |
If you setup your dns server as i have posted a dns server setup blog. then no need to setup above configuration.
Setup Server
Update Repo
sudo -i
apt update && apt upgrade -ySet Hostname matched your mail server domain name
hostnamectl set-hostname mail.shaharul.abc
sudo -iNow edit the host file
nano /etc/hostsand paste as below
127.0.0.1 localhost
127.0.1.1 mail.shaharul.abc mail
192.168.9.91 mail.shaharul.abc mail
Next, we need to install Dnsmasq to create and manage a few DNS records required by Zimbra. We also need to disable systemd-resolve in order to avoid conflict between dnsmasq and systemd-resolve
systemctl disable systemd-resolved
systemctl stop systemd-resolved
ls -lh /etc/resolv.conf
rm -f /etc/resolv.conf
Now create your own resolv.conf
nano /etc/resolv.confset name server as below
nameserver 192.168.9.92
Now install Dnsmasq
apt install dnsmasq -yNow configure Dnsmasq
Edit dnsmasq.conf.bak
cp /etc/dnsmasq.conf /etc/dnsmasq.conf.bak
nano /etc/dnsmasq.confand paste below content at bottom of the file and change ip and server as your.
server= 192.168.9.91
domain=shaharul.abc
mx-host= shaharul.abc, mail.shaharul.abc, 5
mx-host= mail.shaharul.abc, mail.shaharul.abc, 5
listen-address=127.0.0.1
Now dig the command and see A record
root@mail:~# dig -t A mail.shaharul.abc

How to create own DNS server at Ubuntu-Server-20.4 LTS
For Creating own DNS server we need some requirements
1. I am using Ubuntu Server 20.4 LTS server.
2. Domain name: shaharul.abc
3. DNS server Name: ns.shaharul.abc
4. IP: 192.168.9.92
Let's start,
First update repo
sudo apt update
Then install Bind9 package and utils
sudo apt install -y bind9 bind9-utils
Then need to create a zones for DNS server.
sudo nano /etc/bind/named.conf.local
In created zone file we need to add a forward zone and reverse zone. in named.conf.local file paste below configurations.
Forward Zones Config
zone "shaharul.abc" IN { // Domain name
type master; // Primary DNS
file "/etc/bind/shaharul.abc.db"; // Forward Zone file
allow-update { none; }; // Since this is the primary DNS, it should be none.
};Reverse Zones Config
zone "9.168.192.in-addr.arpa" IN { // Reverse lookup name, should match your network in reverse order
type master; // Primary DNS
file "/etc/bind/r.shaharul.abc.db"; // Reverse lookup file
allow-update { none; }; // Since this is the primary DNS, it should be none.
};In the shaharul.abc.db and r.shaharul.abc.db zone file we need to add some record.
Record types in the zone file,
SOA – Start of Authority
NS – Name Server
A – A record
MX – Mail for Exchange
CN – Canonical Name
Edit shaharul.abc.db file
sudo nano /etc/bind/shaharul.abc.db
and paste below configurations and please don't forget to use your domain name server and ip address instead of mine.
$TTL 86400
@ IN SOA ns.shaharul.abc. root.shaharul.abc. (
200101 ; Serial
21600 ; Refresh
3600 ; Retry
604800 ; Expire
86400 ) ; Negative Cache TTL
;
;Name Server Information
@ IN NS ns.shaharul.abc.
;IP address of Name Server
ns IN A 192.168.9.92
;Mail Exchanger
@ IN MX 10 mail.shaharul.abc.
;A – Record HostName To Ip Address
www IN A 192.168.9.90
mail IN A 192.168.9.91
;CNAME record
ftp IN CNAME www.shaharul.abc.Edit r.shaharul.abc.db file
sudo nano /etc/bind/r.shaharul.abc.db
and paste below configurations
$TTL 86400
@ IN SOA ns.shaharul.abc. root.shaharul.abc. (
200101 ; Serial
21600 ; Refresh
3600 ; Retry
604800 ; Expire
86400 ) ; Negative Cache TTL
;
;Name Server Information
@ IN NS ns.shaharul.abc.
;Reverse lookup for Name Server
92 IN PTR ns.shaharul.abc.
;PTR Record IP address to HostName
90 IN PTR www.shaharul.abc.
91 IN PTR mail.shaharul.abc.Edit named.conf.options and uncomment forworders line and make dnssec-validation no; by default it will be dnssec-validation auto;
sudo nano /etc/bind/named.conf.options
Now Make changes to the below lines
forwarders { 8.8.8.8; };
dnssec-validation no;Now we need to check the syntax of DNS configurations
sudo named-checkconf
Also need to check forward zone and reverse zone syntax configurations
To check forward zone syntax configurations
sudo named-checkzone shaharul.abc /etc/bind/shaharul.abc.db
Output should comes with OK status.
To check Reverse zone syntax configurations
sudo named-checkzone 9.168.192.in-addr.arpa /etc/bind/r.shaharul.abc.db
Output should comes with OK status.
Now reload the zones files configurations
sudo rndc reload
Now verify the DNS server is by dig command is it lookup or not.
dig www.shaharul.abc @192.168.9.92
Out put should like this
; <<>> DiG 9.18.1-1ubuntu1-Ubuntu <<>> www.shaharul.abc @192.168.9.92
