DMARC (Domain-based Message Authentication, Reporting, and Conformance) uses SPF and DKIM results to tell receiving servers how to proceed if an email fails security validations.
1. Log in to your cPanel control panel.
2. Scroll down to the Domains section and select Zone Editor.
3. Locate the domain you want to configure in the list and click the Manage button.
4. Click + Add Record within the cPanel zone editor.
5. Configure the technical record variables:
5.1. Type: Select TXT.
5.2. Name: You must enter
_dmarc (the system will automatically append the root domain behind it).5.3. TTL: 14400.
5.4. Value (Value/Record): Enter the recommended base policy for implementation and monitoring phases (None mode, which reports activity without blocking deliveries while you run tests):
v=DMARC1; p=none; rua=mailto:tu@email.com
6. Click Save Record.
Notes:
DMARC policies are configured within this record and dictate three levels of action:
• p=none: Only collects reports and does not block any emails. Useful for monitoring traffic before implementing security.
• p=quarantine: Sends suspicious emails that do not pass authentication tests directly to the spam folder.
• p=reject: Completely blocks the email so that it never reaches the recipient.
