🔎 SPF check#

zone-wide SPF report

DNS lookups: 1/10 · policy: ?all

  • error include:_relayspf.hosting4real.net\010+include:aspmx.googlemail.com has no SPF record: receivers that reach it return permerror (RFC 7208 §5.2)
  • warn "?all" is neutral: it gives receivers no guidance, much like having no SPF
