✍️ DKIM keys#

1 found
SelectorCNAMEKey
mail — RSA · ~1024 bit below 2048 bit

DKIM selectors can't be listed, so we check the common ones (Microsoft 365, Google, Mailchimp, SendGrid, generic). Keys under other selectors aren't shown.

🔎 SPF check#

zone-wide SPF report

DNS lookups: 3/10 · policy: ?all

  • warn "ptr" is slow, unreliable and discouraged (RFC 7208 §5.5)
  • warn "?all" is neutral: it gives receivers no guidance, much like having no SPF
