BIND is very important thing to do before setting up the SMTP server for Bulk Emailing,  Before proceeding BIND in local server, most important step is to make PTR ( Point Domain to IP ) entry first from your ISP’s end. lets read something about BIND DNS.

What is BIND ?

BIND stands for Berkely Internet Name Domain which helps to translate your IP address to Domain name and vice versa. Usually this mechanism you will find in linux servers, BIND DNS has several zones, but in this post I am going to share with you the most important zones to configure before bulk emailing which plays most important role to prevent your Domain and IP address from blacklist during the bulk emailing.

To confirm PTR entry visit following website and check by putting your IP address which should point to your Fully Qualified Domain Name. If it is reflecting then wait 24 to 48 hours before start emailing or do contact your ISP asap. This website shows the blacklisting status also for your IP address


A. Steps to setup BIND

1. Update your system before installing BIND

#  sudo yum update

#  sudo yum install bind


2. You can configure BIND easily using Webmin

How to install webmin

Open webmin page by putting your ip address or FQDN with webmin port in your web browser

Login with root user

Expand Servers category to find and configure BIND DNS, if BIND DNS is not listed in Servers category then you should find in Un-used Modules category.

Go to BIND DNS server you will see the following screen, scroll down and find create master zone.

3. Now, there will be screen for edit master zone, select Address from this windows and put your host name, domain name followed by your IP address as per following. There would be two entries, one for host name and another entry for your domain name.


4. After updating records click on return record type because we will have to update the reverse records for the same


5. Now, Go to Reverse Address


6. In this record we will have to enter IP address first then host name and domain name

C. Create Reverse Address Record

1. Go to create the master zone and make sure you have selected Reverse ( Address to Name ) and fill the details. In my case I am using a class C IP address, therefore my IP address for the reverse record is 192.168.10, identify the class of your IP address then go-ahead


2. After updating details click on create, you will see the following screen. Go to Reverse Address and update the details of your ip address and domain


3. Once update, these entries will look like the following, go back to the zone list

#  sudo systemctl enable named
