SPF and DMARC records for gmx.at

SPF for gmx.at

gmx.at 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 gmx.at

The DMARC policy for gmx.at is p=quarantine: failing mail is delivered to spam rather than refused. It is the common intermediate step between monitoring and rejecting.

Why it matters

SPF says which servers may send as gmx.at; 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 gmx.at is trusted, and whether someone else can pretend to be gmx.at. 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.
