Step-by-step: 10/10 Email Deliverability with SPF, DKIM, DMARC & PTR records
Official Verified Solution
Solved by Imran Hossain
Spot on! The most overlooked step is the rDNS (PTR) record. Many people configure SPF and DKIM properly, but forget to contact their VPS provider to map the server IP back to their hostname.
Also make sure your TLS certificate covers mail.yourdomain.com so Port 587 / 465 encryption succeeds seamlessly without security warnings.
If your business emails from custom domains are landing in Gmail or Outlook spam folders, here is the essential DNS checklist to achieve a 10/10 score on Mail-Tester:
- SPF Record (TXT):
v=spf1 ip4:YOUR_SERVER_IP include:_spf.google.com ~all - DKIM Record (TXT):
Ensure the 2048-bit public key generated in cPanel is active. - DMARC Record (TXT on
_dmarc.yourdomain.com):
v=DMARC1; p=quarantine; rua=mailto:[email protected]; pct=100; sp=none - Reverse DNS (rDNS / PTR Record):
Confirm that your server's IP resolves directly to your hostname (e.g.,mail.yourdomain.com).

Another great tip: always set up a dedicated transactional mail service (or isolated queue worker) for password reset tokens and verification emails so marketing broadcasts never impact critical transactional deliverability.
