Why this rule existsrationale
How to fix itremediation
Schedule a review of inbound messages that produced no keyword match, suppress anything that reads as a revocation, and record when the review ran. Done when the review has a date, an owner and a finding count each time.
A compliant exampleexample
Weekly: export unmatched inbound messages, review, suppress, record "reviewed 2026-03-06, 4 revocations found".
Check this yourselfattestation
No tool can settle this one for you. Here is the check, and what wrong looks like.
Does the review of unmatched inbound messages have a date, an owner and a finding count each time it runs?
- 1Schedule the sweep over inbound messages that produced no keyword match.
- 2Suppress anything that reads as a revocation, and record when the review ran and what it found.
- 3Finding three a month is a working programme. Finding none usually means nobody is looking.
What wrong looks like: No classifier catches everything, so the question is whether anybody ever finds out. Without the review record, a missed revocation looks like the norm rather than an exception.
