spf_expand
shallownet.fmelo/cognita · Verify this server
Fully expand a domain's SPF record: follow every include: and redirect= recursively and count the DNS-lookup mechanisms across the WHOLE tree against the RFC 7208 limit of 10 — the real-world failure spf_check misses, where a nested include quietly pushes the total over 10 and the record hits permerror. Returns the flattened include tree, the total lookup count, and warnings on excess, loops or void lookups. DNS-only, read-only.
