Create a DMARC record in cPanel

Introduction

DMARC is an email authentication policy that helps protect your domain against forged messages. It works together with SPF and DKIM.

If your domain uses a DNS zone managed in cPanel, you can publish the record as a TXT entry.

What DMARC does

With DMARC, you tell receiving servers what to do when a message fails verification:

• none: only monitor.
• quarantine: send the message to spam or quarantine.
• reject: reject the message.

Steps to create it in cPanel

1. Log in to cPanel.
2. Open Zone Editor.
3. Click Manage for the correct domain.
4. Add a TXT record.
5. Use _dmarc as the record name.
6. Paste the DMARC value you want to use.
7. Save the change.

Example policies

Monitoring mode:

v=DMARC1; p=none

Quarantine mode:

v=DMARC1; p=quarantine; pct=100

Reject mode:

v=DMARC1; p=reject; pct=100

Conclusion

Creating a DMARC record in cPanel helps protect the domain reputation and gives you more control over unauthorized email. The key is choosing the right policy for your current setup.
