Domain Email Trust Check

Check the mail-exchange publication, SPF, DMARC, MTA-STS, and TLS-RPT controls a domain currently publishes, in one bounded diagnostic.

"Trust" here means observable published domain controls—not sender identity, message legitimacy, reputation, or deliverability.

This check reports DNS records and policy documents currently published by the domain. It does not verify that messages are legitimate, that senders are authorized in practice, that delivery will succeed, or that the domain has a good reputation.

Enter a public mail domain.

The domain you enter is sent to the Collabovizion diagnostic service to query its currently published email-domain controls. Results are not saved as user history. No account is required.
