DKIM_NO_COMMON_SELECTORS · Severity: Info

• InfoDKIM_NO_COMMON_SELECTORS

  No DKIM key was found under the common selectors that were tried.

  DNS offers no way to list a domain's DKIM selectors, so the check tries a fixed list of names used by common mail providers and generic setups. Finding none is a hint, not proof that DKIM is missing: the domain may sign with a selector that is not on the list.

  Recommendation: Read the s= tag of the DKIM-Signature header in a message from the domain and check that selector with the DKIM record check.
