DKIM signing

live factor #2 · Security & Infrastructure · scoring impl: implemented · weight 2%

What we measure

DKIM cryptographically signs your outgoing emails so recipients can verify they actually came from you. Without it, mail providers can't tell real from spoofed.

How to improve your score

Generate DKIM keys via your email provider (Google Workspace, Microsoft 365, Mailgun, etc.) and publish the public key as a TXT record at the selector your provider specifies.

Scoring

Scoring formulas are versioned with the methodology. The current method (v1.1.0) maps raw measurements to pass, warn, fail. Factor weights determine how much each contributes to the composite — see the methodology index for the full table.
