    note: >-
      The automated probe first returned a resolver timeout string in the caa
      field; that was a transient DNS failure, not a record. Re-queried directly
      against 1.1.1.1 on 2026-08-13 and confirmed by hand.
    caa: No CAA records (three consecutive empty responses from 1.1.1.1).
    spf: >-
      No v=spf1 record. The only TXT records on the apex are ownership
      verifications (MS=, google-site-verification=).
    dmarc: No TXT record at _dmarc.whisperr.net.
    impact: >-
      Material for this provider specifically — Whisperr sends retention email on
      its customers' behalf via a provisioned delivery server, so the absence of
      SPF and DMARC on its own domain is worth the provider's attention.
