DKIM Record Requirements

Required Tags

v= (Version)

Must be "DKIM1"

k= (Key Type)

Usually "rsa" or "ed25519"

p= (Public Key)

Base64 encoded public key

h= (Hash Algorithms)

Recommended: "sha256"

Best Practices

  • Use RSA with at least 2048-bit keys
  • Include SHA-256 in hash algorithms
  • Keep records under DNS size limits
  • Regularly rotate keys (every 6-12 months)
  • Test thoroughly before deployment

Important: DKIM records are critical for email deliverability and security. Ensure your configuration is correct and up to date.
