How To Fix cPanel Email Deliverability DKIM & PTR Records

Email deliverability in cPanel ensures that your emails reach inboxes instead of spam folders. However, without proper authentication, they may still be flagged. To prevent this, you need to configure SPF, DKIM, and PTR records. By doing so, you improve email authentication and reduce the risk of undelivered messages. Moreover, these settings help establish your domain’s credibility, making it less likely for emails to be marked as spam. Therefore, if you want to maintain a strong email reputation, setting up these records correctly is essential.

Understanding cPanel Email Deliverability

cPanel includes an Email Deliverability tool that helps diagnose and fix issues related to outgoing email authentication. It ensures that emails sent from your domain comply with security standards, reducing the chances of landing in spam folders.

Key Components

1. SPF (Sender Policy Framework)
   • SPF prevents spammers from sending emails on your behalf.
   • It specifies which mail servers are authorized to send emails from your domain.
   • You can check or modify SPF records in cPanel under Email Deliverability.
2. DKIM (DomainKeys Identified Mail)
   • DKIM adds a digital signature to emails to verify they are genuinely sent from your domain.
   • If DKIM is misconfigured, recipients might reject your emails or mark them as spam.
3. PTR (Pointer) Record
   • Also known as a reverse DNS record, a PTR record verifies that your mail server’s IP matches your domain.
   • Many email providers reject emails from servers without a valid PTR record.
