How Domain Email Doctor works
The app only reads public DNS records. It does not log in to your mail provider, modify DNS, or ask for your email password.
1. Resolve public DNS
The scanner queries DNS-over-HTTPS for NS, MX, TXT, CNAME, A, and AAAA records using public resolvers.
2. Detect providers
Deterministic patterns identify common DNS hosts, website hosts, and email providers without treating website hosting as mail hosting.
3. Explain exact fixes
The rule engine checks MX, SPF, DKIM selectors, and DMARC policy, then returns concrete records to add, merge, or review.
DKIM note: DKIM selector names are provider-specific. Common-selector checks help, but a missing common selector is not proof DKIM is absent.
