Fix these, in this order
ranked by impactA selector published with an empty key tells receivers to fail any mail signed with it, and no active key was found under common selectors.
Do this: publish a new key under an active selector, or add your real selector to the check if it is one we did not probe.
Either DKIM signing is off, or it uses a selector we did not probe. Without DKIM, forwarded mail and anything that breaks SPF fails DMARC.
Do this: turn on DKIM at your mail provider and at every third-party sender, then add the selector names when monitoring so they are verified daily. If DKIM is already on with an uncommon selector, add it to the check.
dmarc.facebookmail.com has not published facebook.com._report._dmarc.dmarc.facebookmail.com, so receivers will discard aggregate reports sent there.
Do this: ask the report provider to publish the authorisation record, or use an address on your own domain.

DKIM selectors cannot be listed from DNS, so 79 selectors used by common providers were probed. "Not found" means none of those selectors exist; the domain may still sign with a custom selector.
- WarningThe only DKIM selector found (default) is revoked. Mail signed with it fails DKIM.

How the grade is calculated
Score 75/100. SPF present and valid. SPF ends with -all. DMARC present and valid. DMARC policy is reject. DMARC aggregate reporting enabled. SPF contributes up to 35 points, DKIM up to 25, DMARC up to 40 (policy strength and reporting). Any critical issue caps the grade at C. Lookups that failed are shown as "not measured" and never counted as missing.
