1 fix stands between this domain and a clean A. 1 item below, ordered by how much inbox it is costing you.
Fix these, in this order
ranked by impactEither 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: in Microsoft 365 Defender go to Email & collaboration → Policies → DKIM, publish the two CNAME records (selector1 and selector2) and enable signing.

2 / 10DKIM Not found
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.
- WarningNo DKIM key found under 79 common selectors. If you know your selector, add it to the check; if you have no DKIM at all, enable it at your mail provider.

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.
