The most common causes are a missing or misconfigured SPF/DKIM/DMARC record, sending from a domain with no DMARC policy, or exceeding the 10 DNS lookup limit for SPF. Run a scan to see exactly what's wrong.
We cache scan results for 24 hours to avoid hammering DNS providers, and store history only for domains you explicitly add to a monitored account.
