ThreatEmail headers

Reply-To routes corporate sender to free webmail — payroll/vendor/CEO fraud signature

reply-to-corporate-to-freemail

What this tier means

High-confidence threat indicator — phishing, impersonation, BEC, or scam pattern. Strong contributor to the trash decision.

How Gorganizer detects this

From address is on a corporate domain but Reply-To routes replies to a free webmail address (gmail, outlook, yahoo, protonmail, etc.). The attacker compromised or spoofed the corporate sender and wants the victim's reply to land in a personal mailbox they actually control — classic payroll-diversion fraud, vendor impersonation, and CEO-wire-fraud signature. Corporate senders never legitimately route replies to gmail: they use their own corporate domain for both From and Reply-To.

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.
