SPF and DMARC records for adv-dep-eng.jo3.org

SPF for adv-dep-eng.jo3.org

adv-dep-eng.jo3.org publishes no SPF record. Receiving servers cannot tell which servers are allowed to send as adv-dep-eng.jo3.org, so mail from the domain is easier to spoof and more likely to land in spam. A basic record (v=spf1 include:… -all) fixes that, and Spaw's risk score adds a small weight to addresses at domains without one.

DMARC for adv-dep-eng.jo3.org

adv-dep-eng.jo3.org 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 adv-dep-eng.jo3.org.

Why it matters

SPF says which servers may send as adv-dep-eng.jo3.org; 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 adv-dep-eng.jo3.org is trusted, and whether someone else can pretend to be adv-dep-eng.jo3.org. 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.
