This is protection: the message is part of a thread continuation, which means you (or someone in your circle) is actively engaged with the sender. Same protection class as `reply-or-forward` but triggered via the RFC 5322 header fields instead of subject-prefix heuristics.","tier":"warning","category":"other","isThin":false}}
