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

Step 1: Log into Your BigRock Account

1. Visit the Namecheap Website: Open your web browser and go to Namecheap’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 Your Domain Management

1. Navigate to the Dashboard: After logging in, you will be directed to your account dashboard.
2. Select ‘Manage Orders’: In the dashboard, look for the “Manage Orders” section.
3. View Your Domains: Click on “List/Search Orders” to see a list of all the domains you own.

Step 3: Choose the Domain

1. Select the Domain: From the list of domains, click on the domain name for which you want to add a DNS record.
2. Manage Domain: On the domain management page, look for an option that says “Name Servers” or “DNS Management.”

Step 4: Access DNS Management

1. DNS Management Option: Click on “DNS Management” to enter the DNS settings for your selected domain.
2. Manage DNS: You will now be in the DNS management interface where you can view and edit your DNS records.

Step 5: 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.

Step 6: Enter Record Details

1. Record Type: Choose the appropriate record type from the dropdown menu.
2. Host/Name: Enter the subdomain or the main domain. For example, for an A record, this might be “www” for www.yourdomain.com or “@” for the root domain.
3. Value/Address: Enter the IP address, domain name, or other value required by the record type. For example, an A record might need an IP address like “192.0.2.1”.
4. TTL (Time to Live): Enter the TTL value which dictates how long the record is cached by DNS resolvers. The default value is usually fine if you’re unsure.

Step 7: Save the DNS Record

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

Step 8. 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 Namecheap’s own DNS lookup feature.

Step 9. 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 Namecheap documentation or support resources for further guidance.

Step 10: Propagate DNS Changes

1. Wait for Propagation: DNS changes can take anywhere from a few minutes to 48 hours to propagate across the internet.

Check Propagation: You can use online tools like DNSChecker.org to see if your new DNS record has propagated.
