SPF and DMARC records for 1-box.ru

SPF for 1-box.ru

1-box.ru publishes an SPF record; it names its senders directly rather than through include mechanisms, and the record has no explicit all mechanism, so receivers treat unlisted servers as neutral.

DMARC for 1-box.ru

1-box.ru publishes no DMARC record. Receivers have no policy to apply when SPF or DKIM fails, and the domain owner receives no aggregate reports about who is sending as 1-box.ru.

Why it matters

SPF says which servers may send as 1-box.ru; DKIM signs the messages; DMARC tells receivers what to do when neither checks out and reports back to the owner. Together they decide whether mail from 1-box.ru is trusted, and whether someone else can pretend to be 1-box.ru. For verification they are a domain-quality signal: Spaw folds a missing SPF record into the risk score and reports has_spf and dmarc_policy on every email and domain lookup.
