 "why_it_matters": "`~all` is the SPF equivalent of `p=none` and overwhelmingly the most common configuration — it asks receivers to accept-but-mark, so spoofed mail still arrives. `+all` authorises the entire internet to send as you. Exceeding the 10-lookup limit makes the record fail *permanently and silently*, because receivers abort evaluation.",
 "limits": "The lookup count is **non-recursive** (it does not expand `include:`), so it is a lower bound and catches only egregiously over-limit records.",
