Mail · Spf Flatten

Unfold a domain's SPF policy (RFC 7208) into merged IPv4 and IPv6 blocks: include and redirect followed as a receiver counts them (10 lookups, 2 void lookups, PermError stops), a and mx resolved with /cidr, sources per block, exists, ptr and macros listed apart, and very broad blocks flagged. Use when an agent must know which servers may send. Input: ?domain=example.com.
