Understanding DMARC: A Quick Overview
DMARC combines SPF and DKIM to authenticate emails, providing enhanced security and preventing unauthorized use of your domain.
Step 1: Access Your DNS Provider Account
Log in to your DNS provider’s account, which hosts your domain’s DNS settings.
Step 2: Locate DNS Management
Find the section labelled “DNS Management” or “DNS Settings.” This is where you’ll manage your domain’s DNS records.
Step 3: Add a DMARC Record
- Choose Record Type: Select the option to add a new DNS record. Choose “TXT” as the record type.
- Enter Host Value: In the “Host” field, input “_dmarc” to indicate this is a DMARC record.
- Set TXT Value: For the “TXT Value,” enter your DMARC policy. Example: “v=DMARC1; p=quarantine; rua=mailto:[email protected].”
Step 4: Define Your DMARC Policy
- v: Version of DMARC (currently “DMARC1”).
- p: Policy setting (“none” for monitoring, “quarantine” for sending to spam, or “reject” for blocking).
- rua: Email address to receive DMARC aggregate reports.
Step 5: Save Changes
After entering the DMARC policy, save your changes and wait for DNS propagation.
Step 6: Monitor and Analyze DMARC Reports
Regularly review the DMARC aggregate reports to understand email sources using your domain and take necessary actions based on the findings.
Common Mistakes to Avoid
- Incorrect Syntax: Ensure your DMARC policy syntax is accurate to avoid configuration errors.
- Missing Policy: Clearly define your policy to indicate how email servers should treat failed authentication emails.

FAQs
Q1. How does DMARC work with SPF and DKIM?
A) DMARC works alongside SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to authenticate emails. SPF specifies authorized servers, DKIM adds digital signatures, and DMARC sets policies for handling authentication results.
Q2. Which DNS vendors can use this guide to set up DMARC?
A) This guide is applicable to a wide range of general DNS vendors, making it suitable for anyone using different DNS providers for their domains.
