Checking records…
How email authentication works
SPF lists which servers may send mail for your domain. DKIM cryptographically signs each message so receivers can verify it was not tampered with. DMARC ties SPF and DKIM together and tells receivers what to do when a message fails both checks (monitor, quarantine, or reject). MX records say where mail for your domain should be delivered.
DKIM records are namespaced by a selector, which is chosen by whoever sends mail on your behalf. We can’t guess it, so you’ll need to tell us the selector (common values: google, default, selector1, k1, dk).
Lookups go directly from your browser to the chosen DNS-over-HTTPS resolver. StatusDrift never sees your query.
