Email Authentication Records – SPF, DKIM and DMARC

SPF, DKIM and DMARC are DNS records that help prevent email spoofing and ensure your emails reach recipients’ inboxes rather than spam folders.

SPF (Sender Policy Framework)

SPF specifies which mail servers are authorised to send email on behalf of your domain.

How to Add an SPF Record

  1. Log in to cPanel ? Zone Editor
  2. Click Manage next to your domain
  3. Click Add Record ? Add TXT Record
  4. Name: yourdomain.co.za
  5. Value: v=spf1 +a +mx +ip4:YOUR_SERVER_IP ~all
  6. Click Add Record

Contact our support team for your exact server IP address.

DKIM (DomainKeys Identified Mail)

DKIM adds a digital signature to your outgoing emails so recipients can verify they came from you.

How to Enable DKIM

  1. Log in to cPanel
  2. In the Email section, click Email Deliverability
  3. Click Manage next to your domain
  4. Click Install the suggested records

DMARC (Domain-based Message Authentication)

DMARC builds on SPF and DKIM to tell recipient servers what to do with emails that fail authentication.

Basic DMARC Record

  1. Add a TXT record in Zone Editor
  2. Name: _dmarc.yourdomain.co.za
  3. Value: v=DMARC1; p=none; rua=mailto:[email protected]

Start with p=none (monitor only), then move to p=quarantine or p=reject once you are confident in your email setup.
