SPF and DMARC records for a-bc.net

SPF for a-bc.net

a-bc.net publishes an SPF record; it names its senders directly rather than through include mechanisms, and the record ends in -all (hard fail): mail from a server that is not listed should be rejected.

DMARC for a-bc.net

a-bc.net 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 a-bc.net.

Why it matters

SPF says which servers may send as a-bc.net; 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 a-bc.net is trusted, and whether someone else can pretend to be a-bc.net. 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.
