What this check does not do
This is a snapshot of public DNS configuration, not a complete security audit or a guarantee of email delivery. DKIM requires a selector, and MTA-STS policy-file availability is not tested in this browser-only version.
Need help fixing a result?
Good email security depends on more than one record.
Kiwinove can review Microsoft 365, DNS and mail authentication together, explain the risks and make changes without disrupting legitimate mail.

DNS & Email Health Checker: practical help, clear next steps.
Review public DNS and email authentication settings for a domain. Use the findings to prepare a focused conversation with your email administrator.
How to use this tool
- Enter a domain name, without an email address or a page path.
- Choose a DKIM lookup option. Use a known selector if your email provider supplies one.
- Run the check, review each explanation and download your results.
Common questions
What if I do not know the DKIM selector?
Choose the unknown-selector option. The tool can try common selectors, but cannot discover every possible selector. An inconclusive lookup is not proof that DKIM is missing.
Does a healthy result guarantee email delivery?
No. Public DNS is only part of email delivery and security. Tenant settings, message content, sending reputation and receiving systems also matter.
