Try 27 common DKIM selectors (Google, Microsoft 365, Mailchimp, SendGrid, Mailgun, Zoho, Proton, Fastmail, Mailjet, Amazon SES and generic names) for a domain and validate every key found: type, size, revocation and testing flag. Use when an agent needs a domain's DKIM keys but does not know the selector. Finding none is a hint, not proof that DKIM is missing.
