SPF for t-online.de
t-online.de publishes an SPF record; it names its senders directly rather than through include mechanisms, and the record ends in ~all (soft fail): mail from unlisted servers is marked suspicious but usually still delivered.
DMARC for t-online.de
The DMARC policy for t-online.de is p=none: the domain collects authentication reports but asks receivers not to act on failures. Spoofed mail is still delivered; the owner just gets told about it.
Why it matters
SPF says which servers may send as t-online.de; 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 t-online.de is trusted, and whether someone else can pretend to be t-online.de. 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.
