FAQ
Información útil
How do I use DKIM Record Checker?
1. Enter domain and selector: Read d= and s= from a real DKIM-Signature header or use your email provider’s instructions. 2. Query the exact record: Look up selector._domainkey.domain using Google Public DNS. 3. Inspect returned records: Review TXT and CNAME answers with your provider. This does not test a message signature.
Can the tool discover every selector?
No. You must supply the selector. Failure to find one selector does not mean the domain has no DKIM.
Does a published key prove DKIM works?
No. Signing, key validity and signature verification require inspecting real messages. This tool reports DNS answers only.
