A relevant record was found without the common issues checked here. It does not guarantee inbox placement, a working mail server or successful authentication of every email.

DKIM keys live under selectors chosen by your provider. Without one, there is no reliable way to list every key. Check the selector used in a recent sent email.

References: SPF (RFC 7208), DKIM (RFC 6376), DMARC (RFC 9989). DNS answers can differ while changes propagate.
