Smash Email Spoofing and DNS Confusion with autonomous DNS and header analysis.
Paste raw email headers to trace routing hops and verify SPF, DKIM, and DMARC authentication status.
Recursively resolve nested SPF mechanisms into a static record, preserving dynamic macros.
Generate CNAME routing targets to delegate DMARC policy management directly to Sledgeheader.
Instantly generate selector CNAME rules for external email service providers.
Detect invalid tags, missing semicolons, deprecated PTR mechanisms, or dangerous +all rules.
Upload aggregate reports (.xml, .gz, .zip) to parse headers and stream records into BigQuery analytics.
