Extensions: Email Security bulk remediation, verdict revisions and the managed-detection switch

New Features

  • Bulk remediation over a selection you name. Any search result — a filtered page of the queue, a hunt, a list of ids in a file — can now be remediated at the provider in one operation, with the campaign sweep's preview-then-confirm discipline: POST /actions/bulk/preview reports each message's current state and the distinct-mailbox blast radius and mints a confirmation derived from that exact selection, POST /actions/bulk/execute returns a bulk_id immediately and paces the provider writes in the background, and GET /actions/bulk/{bulk_id} reports per-message outcomes and running counts. Capped at 500 per call, refused rather than truncated above it. limacharlie mailsec message bulk-action wraps the pair, reads its selection from --msg-uuids, --input-file or standard input, and carries the outcome in its exit code.
  • Verdict revisions are documented end to end. POST /messages/{msg_uuid}/verdict re-judges one message in the analyst or ai seat with a required rationale, and GET /messages/{msg_uuid}/revisions serves the whole append-only chain with the prior state each revision displaced. Re-recording a verdict a message already carries is a success reporting applied: false, not an error. Revising requires mailsec.act rather than mailsec.set, because it can promote a message's evidence to the 400-day lane and emits an EMAIL_VERDICT.
  • A resolved user report can be reopened. POST /reports/{report_id}/reopen (limacharlie mailsec report reopen) puts a report back in the queue and keeps its resolution columns, so the row still reads "previously resolved by …" rather than erasing what is being disputed. It is the escape hatch the abuse-mailbox auto-resolver depends on.
  • The managed detection pack has a documented switch. The managed_rules policy record, the console's Settings toggle, and the set_managed_rules / get_managed_rules extension actions all write the same thing. Absent means enabled; a record that states no value is refused; a change reaches the pipeline in seconds, with a five-minute backstop.
  • Link detonation is documented: what triggers it (a suspicious verdict with links, up to five URLs per message), the organization-wide claim that makes a campaign cost one fetch, every refusal reason, and what a mode: detonation verdict revision means — including that it never overrules a person or an agent.
  • Time to verdict is a real number. coverage's overview.processing_latency_p95 reports p50/p95/p99 with the basis it measures, the denominator it measured over, and — when there is no number — which of the two honest reasons applies. Backfilled and re-driven mail is excluded so a recovery cannot report a latency measured in days.
  • New Troubleshooting page: the entitlement gate (mail that arrives while unsubscribed is never read and is never backfilled), watch renewals, silent-mailbox stalls, EMAIL_INGEST_ERROR, connection handover during a platform update, and the 30-day deletion clock.
  • Custom rules now document scope versus the ? path wildcard — only scope correlates two conditions on the same link or attachment — and state plainly that a rule using lookup, or a post_verdict rule, cannot be backtested.

Extensions: Email Security tenant purge

New Features

  • Tenant purge for Email Security: everything Email Security holds for an organization can now be deleted on request — the message index and the up-to-400-day evidence lane, campaigns, sender profiles, the product's action audit trail, user (abuse-mailbox) reports, stored raw messages and their parsed copies, link-detonation results, and the organization's provider connection and policy configuration. The purge also stops the mail connections at Microsoft 365 and Google Workspace, so the provider stops sending notifications instead of repopulating the index. It is irreversible, requires Owner-level authority (mailsec.act, billing.ctrl and user.ctrl together), and is recorded in the organization's audit log with the caller's identity and an optional reason.
  • The purge is two steps, and previews by default: limacharlie mailsec tenant purge prints the warning and mints a single-use confirmation token that expires in five minutes, and destroys nothing until that token is passed back with --confirm. A purge that reports complete: false did not finish and can simply be re-run with a fresh token. The Python SDK exposes the same pair as Mailsec.prepare_tenant_purge() and Mailsec.purge_tenant().
  • Email Security data is now also deleted automatically: 30 days after an organization unsubscribes from the extension — resubscribing at any point inside that window cancels the scheduled deletion — and immediately when the organization itself is deleted.
