Check a domain and its mail

Expiry, registrant, SPF, DMARC, nameservers. The same things I look at before touching anything, on your domain, now.

I read public information only: DNS, the registry, whether the site answers. No email address needed, and nothing of yours is stored.

What it looks at

  • Expiry and registrant
    When it expires and whose name it is registered in.
  • SPF
    Whether it exists, whether there is exactly one, and how many of the ten allowed lookups it burns.
  • DMARC
    Whether it exists, and whether it actually tells recipients to reject the fakes.
  • Mail and nameservers
    Where the mail goes, who answers for the domain, whether Cloudflare is in front.

DKIM is missing from the results for a reason: from outside, without knowing the selector, it cannot be verified. Anyone who says otherwise is guessing.
