Module email_policy 

Email allow/block list normalization and matching helpers. Email allow/block list normalization and matching helpers.

Product crates still decide which configuration keys contain allowlists or blocklists, which API error codes to return, and whether an empty allowlist means “allow everyone” or “deny everyone”. This module only owns the shared mechanics for parsing policy entries, normalizing them, deduplicating them in a stable order, and testing exact email/domain matches.
