The hold action now holds (dlp-and-mail-flow-rules spec, §2.6), where until now it blocked. - At DATA a hold decision queues the message with its release a century off (the queue's future-release mechanism, so the stored format is unchanged and an older node just never sends it), transport rules still applied, and replies 250 Held for review. A review record under R/h + queue id keeps the sender, recipients, subject, size, rules and detector counts. The sender is told when the rule asks. - smtp/queue/held.rs: release (each recipient due now, its next notice as far off as it was, its lifetime counted from the release), reject (removed from the queue, the sender told, with the reviewer's note), and expiry: the daily clean-up rejects what nobody reviewed in 7 days, recorded as the server's doing. - inbuxa:HeldMessage get/set: the review queue, sysDlpReviewGet to list and read (preview, 64 KB of text, only when asked for and recorded as blobAccess), sysDlpReviewUpdate to release or reject, a reason required and audited by the request layer; no create or destroy; server-level only. - Guards: Emails > Queue refuses to change or delete held mail; the sender can't unsend it. - Privacy catalog entry for inbuxa:HeldMessage; spec §2.6 as built. Tests: mail_rules_tests gains the whole flow (held and listed with counts, sender notified and nothing delivered, queue and unsend refused, preview recorded, reject needs a reason and tells the sender the note, release delivers, expiry returns it, decisions audited with reasons). smtp inbound, system_tests (after one BlobNotFound in antispam, the known flake, then clean), features and common unit tests.
