ProbeKit

Fetch and validate the DKIM public key record at selector._domainkey for a domain: key type, key size, revocation and syntax, with coded findings. Use when an agent knows the selector (s= in a DKIM-Signature header) and must confirm that the key is published and usable. It does not verify message signatures.
