I agree to share these results and my inquiry under the privacy notice.

Only your latest check can be attached, for 30 minutes. Review URLs and results before sharing sensitive details.

How to use this tool

Enter the domain after the @ in your email address. Add your provider’s DKIM selector if you know it. Actual message signing and alignment require a test email.

One report reuses the existing checks with a shared 20-second limit. Unavailable checks stay marked Unknown. Download, print or share your results; no public report URL is created.

Checks are limited to public Internet hosts. We use short timeouts and small responses to keep this service lightweight.

DNS queries use Google Public DNS; domain registration queries use public RDAP services. Privacy details.
