SPF for sina.com
sina.com publishes an SPF record; it authorises 1 included sender list, and the record ends in -all (hard fail): mail from a server that is not listed should be rejected.
DMARC for sina.com
sina.com has DMARC in monitoring mode (p=none). Receivers report what they see but deliver failing mail anyway, so the record protects nothing yet.
Why it matters
Receivers use SPF, DKIM, and DMARC together to decide whether a message really came from sina.com. A domain with a strict SPF record and an enforcing DMARC policy is hard to spoof and easier to deliver for; one without either is neither. Spaw reports has_spf and dmarc_policy on every lookup and adds a small risk weight when SPF is missing.
