Module mail_rules 

Mail rules engine — evaluates a mailbox’s MailRules against an inbound message.

This is a pure decision layer: no filesystem, no network, no clock. Given the rules configured on an address (a rule-bearing mailbox) and an InboundMessage, it returns a MailVerdict describing whether the message is delivered, quarantined, or rejected, plus the priority/notify hints and a human-readable trail of reasons for auditability.

The rules themselves live on crate::domains::MailRules; this module only interprets them.
