The Checkpoint Harmony Email (Avanan) whitelist and blacklist surface: the match fields and matching modes an exception accepts, the defaults that widen an entry beyond what was typed, the id mismatch between listing and editing, and the standing security consequence of a detection bypass.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Checkpoint Harmony Email Exceptions ## Overview Exceptions are Harmony Email's two standing lists. A **whitelist** entry exempts matching mail from the detection engines; a **blacklist** entry condemns it. They are the only configuration surface this plugin can write, and each entry persists tenant-wide until someone removes it. MSP work here is adding narrow, justified entries and auditing the ones that accumulated. ## Anti-triggers - **Policy configuration** — enabling, disabling, tuning or scoping a security policy, adjusting engine sensitivity, editing DLP rules or impersonation-protection rosters. **No tool in this plugin reaches any of it**, and no sibling skill covers it; that work is console-only. Exceptions are not policies. - **Delivering one held message** — a release is a message action, not a list entry. Use `avanan-quarantine`. - **Which policy or engine fired** — use `avanan-threats`. - **Microsoft 365 tenant policy** — conditional access, transport rules and security baselines are not Harmony Email exceptions. Use `cipp-standards` or `cipp-mailboxes`. - **Another vendor's lists** — SpamTitan is `spamtitan-lists`. The `mimecast` …

How to install
mdr add wyre-ai/msp-claude-plugins/Checkpoint Avanan Exceptions@sha256:1a4d583fa3c32c2bThe line at the top of this page pins the label git:20260817.2671d27, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
