cPanel DNS Email Setup Debugger

Find MX, SPF, DKIM, DMARC, and cPanel mail routing mistakes.

Paste your domain, DNS records, provider context, and bounce text to diagnose why cPanel or shared-hosting email does not receive, authenticates poorly, or lands in spam.

Security note: do not paste mailbox passwords, cPanel passwords, API keys, private DNS portal tokens, or private customer mail. DNS records and redacted bounce text are enough.

What this checks: MX routing, cPanel Local vs Remote Mail Exchanger clues, provider mismatch, one-record SPF shape, DKIM selector clues, DMARC strictness, Cloudflare DNS-only mail guidance, and common bounce phrases.
