View DKIM public records for MX, SPF, DMARC and the specified selector.

Only public DNS records are supported, please do not fill in internal or sensitive domain names.

No query has been made, filling in or loading examples will not initiate a request.

Instructions for use

  1. Enter the domain name for sending and receiving emails; if you need to check DKIM, fill in the selector given by the service provider.
  2. Look separately at the MX, SPF in the root domain TXT, _dmarc TXT, and optionally the DKIM record.
  3. View records, TTL, status and query time, which can be copied or cleared; modifying the input will cancel the old query.

Input and output examples

Example input
example.com; selector left blank
Example output
Initiate MX, TXT, and _dmarc.example.com TXT respectively for a total of 3 queries.

The above is a demonstration only, not real-time results. Public DNS records change, and an empty response has different meanings than a failed query.

FAQ

No. Only public DNS is checked, SMTP is not connected, SPF include/redirect is not performed, DMARC organization domain fallback is not performed, and email DKIM signature is not verified.

Calculation basis and reference materials

Look separately at the MX, SPF in the root domain TXT, _dmarc TXT, and optionally the DKIM record.
