Phase 2g of the DLP and mail flow rules spec: transport rules now act, on outgoing and incoming mail. - features/mailflow/rewrite.rs: add or remove a header, prefix or set the subject (an RFC 2047 word when not ASCII), add a disclaimer. A disclaimer edits the message's main text and HTML bodies only, each decoded, changed and written back as UTF-8 quoted-printable with its other headers kept, top or bottom (after <body> or before </body> in HTML); attachments and attached messages are left alone, and a disclaimer already present isn't added again. - smtp/inbound/mailflow.rs: the check runs for incoming mail too (transport rules only; DLP stays outgoing). After DLP passes, each matched transport rule's actions run in order: message edits, add-recipient and redirect (envelope changes DATA applies), route (a per-message queue ahead of the queue strategy), refuse (550 5.7.1 with the rule's text). The override tag is stripped with the same subject writer, so a non-ASCII subject stays valid. - Audit: refusals and changes to where mail goes are recorded (sender, or system:mail-flow for incoming mail); wording and header changes aren't, or a banner rule would record every message (spec §2.7). Tests: rewrite unit tests (headers, encoded subjects, disclaimers on a single part and on multipart/alternative with an attachment, once only); mail_rules_tests gains the actions end to end: disclaimer, header and subject prefix on a delivered message, a redirect, a refusal, a banner on incoming LMTP mail that outgoing rules leave alone, and which of those are audited.
