CLI command

tinbox check-sending-domain

Check a domain's live DNS / verification state — re-runs the DNS check now and returns which records are verified (MX/SPF/DKIM/DMARC) and which are still missing, plus whether receiving and sending are valid. Read-only (it changes no config; it just checks). Use to answer 'is my domain verified yet?' during onboarding, or to point the operator at the exact records still to add in Settings → Domains. Give the domain (e.g. yourdomain.com).
