How to Configure Email Authentication (SPF, DKIM, DMARC) in cPanel

Setting up SPF, DKIM, and DMARC records protects your domain’s emails from spoofing, phishing, and other email-based attacks. Here’s how to enable these essential records in cPanel.

Step 1: Log in to Your cPanel Account

Access your cPanel dashboard with your login credentials.

Step 2: Access Email Deliverability Settings

From the cPanel home page, go to the Email section and select Email Deliverability.

Step 3: Choose the Domain for Configuration

On the Email Deliverability page, locate and select the domain you wish to configure. Then, click Manage next to it.

Step 4: Set Up SPF Record

  1. Under the SPF Record section, confirm that the necessary IP addresses and domains (such as mail servers or email providers) are authorized to send emails on behalf of your domain.
  2. If needed, click Customize to add specific entries.

Step 5: Enable DKIM Signing

Scroll down to DKIM and make sure it is enabled. If not, toggle it to activate. This will add a digital signature to each outgoing email to verify authenticity.

Step 6: Configure DMARC Record

  1. To add a DMARC record, click Add a New Record in the DMARC section.
  2. Choose your policy level (e.g., p=none to monitor, p=quarantine to filter suspicious messages, or p=reject to block them).
  3. Specify a report email if you want to receive reports on DMARC activity.

After setting up each record, click Save to finalize your configurations.

Final Step: Verify Authentication

Send a test email to check your new settings. Use tools like MX Toolbox to verify your domain’s SPF, DKIM, and DMARC status.
