Question 1

What is DKIM Checker?

Accepted Answer

Check DKIM (DomainKeys Identified Mail) records for email signing verification.

Question 2

How does DKIM Checker work?

Accepted Answer

This tool looks up the DKIM record at selector._domainkey.domain.com. The selector is a name chosen by the domain owner (common selectors: default, google, selector1, selector2, k1, etc.).

Question 3

How do I interpret DKIM Checker results?

Accepted Answer

Results show the DKIM public key and its parameters. A valid DKIM record should contain a public key (p=) and version (v=DKIM1). The record is used by receiving mail servers to verify email signatures.
