✍️ DKIM keys#

1 found

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: 4/10 · policy: ?all

warn "?all" is neutral: it gives receivers no guidance, much like having no SPF
