Publishing a DMARC (Domain-based Message Authentication, Reporting, and Conformance) record with BigROCK is a relatively simple process. Here’s a step-by-step guide:

Step 1: Log into Your BigRock Account

1. Visit the BigRock Website: Open your web browser and go to BigRock’s official website.
2. Login: Click on the “Login” button located at the top right corner of the homepage.
3. Enter Credentials: Enter your registered email ID and password, then click “Login.”

Step 2: Access DNS Management

1. Login to your Control Panel, search for the domain name and proceed to the DNS Service interface. 
2. Click the Manage DNS link. The DNS Management Console will pop-up through which you may add any of the following Records:

Step 3: Add a New DNS Record

1. Add Record: Look for a button or link that says, “Add Record” or “Add New Record.”
2. Select Record Type: You will need to select the type of DNS record you want to add. Common types include:

A Record: Points a domain to an IPv4 address.

AAAA Record: Points a domain to an IPv6 address.

CNAME Record: Points a domain to another domain name.

MX Record: Directs email to mail servers.

TXT Record: Provides text information to sources outside your domain.

Click TXT Records and in the next screen, click Add TXT Record.

There you would see 3 fields:

1.Host Name: If you wish to Add a TXT Record for yourdomainname.com like yourdomainname.com, then leave the Host Name text box blank.

2.Value: 255 characters of free form text can be provided in this field. This Record is generally used to convey information about the zone.

For example, you may add a TXT Record for mail.yourdomainname.com with the value as This is my email server. Here if anybody was checking ALL or TXT Records of mail.yourdomainname.com, they would notice the above text appearing in the TXT Record.

3.TTL: This is the Time To Live for this Record. Any Server which once queries this Record will query it again after this time interval. The ideal TTL is 86400, which is 1 day. It can not be set to less than 14400, i.e., 4 hours.

Step 4: Save the DNS Record

1. Save Changes: After entering all necessary details, click “Save” or “Add Record.”

Step 5.Verify the DMARC Record:

It may take some time for the DMARC record to propagate. You can verify its proper publication using a DMARC record checker tool or Bigrock’s own DNS lookup feature.

Step 6.Monitor and Adjust:

Regularly review your DMARC reports and, if necessary, adjust your DMARC policy to improve email authentication and security.

Please note that the specific steps and terminology may vary slightly within the DNS Namecheap interface. If you encounter any difficulties or if their interface has been updated, it’s advisable to consult BigROCK documentation or support resources for further guidance.

Step : Propagate DNS Changes

1. Wait for Propagation: DNS changes can take anywhere from a few minutes to 48 hours to propagate across the internet.
2. Check Propagation: You can use online tools like DNSChecker.org to see if your new DNS record has propagated.
