PGP/S-MIME encrypted body + weak sender auth (envelope phishing)
encrypted-payload-no-reputation
What this tier means
High-confidence threat indicator — phishing, impersonation, BEC, or scam pattern. Strong contributor to the trash decision.
How Gorganizer detects this
Email body is fully encrypted via PGP (-----BEGIN PGP MESSAGE----- block) or S/MIME (Content-Type: application/pkcs7-mime; smime-type=enveloped-data) AND the sender authentication is weak (no dkim=pass, no spf=pass) AND the sender domain is not in the trusted brand allowlist. Attackers route phishing payloads through encrypted envelopes specifically because the engine cannot read the ciphertext to score body-level signals. Legitimate enterprise PGP/S-MIME senders DKIM-sign their envelope wrappers, so the auth-pass gate suppresses the signal for genuine encryption use-cases. PGP signed-only and S/MIME signed-data variants do not fire (the body remains readable).
False-positive guard
Every signal in Gorganizer feeds a multi-module score — never a sole verdict. This is a threat-tier signal — it adds a strong contribution to the trash score. The full pipeline still requires convergence across multiple modules + a margin over the safety floor before deletion happens, and Gmail's trash (30-day recovery) is always used — never permanent delete.
About the scoring engine
Gorganizer's scoring engine emits over 1,800 signals across six modules — headers, sender, subject, body, attachments, and structural metadata. Every email is scored by every module independently; the final verdict requires multiple modules to agree and the trash score to beat the safety floor by a margin.
Sacred safety guards — never delete starred emails, replies, calendar invites, receipts/invoices, or attachments — apply unconditionally regardless of any signal.
