How the grade is calculated
Score 95/100. SPF present and valid. DKIM found (2 selectors). DKIM key is 2048-bit or stronger. 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.
