Why it matters
SPF says which servers may send as centurylink.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 centurylink.net is trusted, and whether someone else can pretend to be centurylink.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.
