check_domain
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), 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.
Parameters2
| domain | string | required | The domain to check, e.g. example.com. No scheme or path. |
| include_smtp | boolean | optional | Also run a live SMTP connectivity probe of the MX hosts. Non-blocking: poll by re-calling until smtp_status is complete. |
