DKIM_RECORD_MISSING

error

No DKIM record was found at this selector, so messages signed with it cannot be verified.

Something is wrong and mail or certificates are affected.

How we know

dkim.test
DKIM semantics as distinct from wire-level mangling: revoked (empty p=), a real 512-bit key, testing mode, wrong version, v= not first, unsupported algorithm, and a non-DKIM TXT sharing the selector. Every key is real and parses with node:crypto.
