check_dkim
Check DKIM
Check DKIM signing keys for a domain. Without a selector, common provider selectors are probed. Pass an explicit selector to look up that exact key at selector._domainkey.

check_domain
Full email deliverability check
Run the full email and DNS deliverability check for a domain: MX, SPF, DKIM, DMARC, DNS health, provider detection, and blacklists. Returns a letter grade (A+ to F, where specific weaknesses cap the grade), a 0 to 100 score, and every individual check with its RFC reference. Set include_smtp to also run a live SMTP probe of the mail servers: the probe is non-blocking, so when smtp_status is "pending" or "running" call this tool again (poll_after_seconds hints how long to wait) until smtp_status is "complete" and the SMTP checks appear in checks.
