5. Configuring DNS resolution:
You should have a domain name with A and Mx Record. If you have already DNS server then just need to Make entry of A and Mx record of of our Mail Server in DNS. In case if you do not have DNS server then you can use any DNS resolution server, including dnsmasq, systemd-resolved, and bind.

Steps to configure Dnsmasq:
1. Install Dnsmasq
apt install dnsmasq -y
2. Disable systemd-resolve
systemctl disable systemd-resolved
systemctl stop systemd-resolved
3. Recreate /etc/resolv.conf
rm -f /etc/resolv.conf
nano /etc/resolv.conf
5. Configure Dnsmasq:
nano /etc/dnsmasq.conf
Insert the following content at the bottom and don’t forget to replace the IP address and domain name
server=1.1.1.1
mx-host=linuxworldwithgk.tk,mail.linuxworldwithgk.tk,50
host-record=linuxworldwithgk.tk,172.31.43.8
host-record=mail.linuxworldwithgk.tk,172.31.43.8
Now save the file and restart dnsmasq by following command
systemctl restart dnsmasq.service
