Reply-To header has multiple addresses — harvest-ring fan-out
reply-to-multiple-addresses
What this tier means
High-confidence threat indicator — phishing, impersonation, BEC, or scam pattern. Strong contributor to the trash decision.
How Gorganizer detects this
The Reply-To header contains two or more email addresses separated by commas. RFC 5322 permits this, but legitimate transactional and marketing email essentially never uses it. Attackers set multiple Reply-To addresses so a victim's reply fans out to a harvesting ring — every address on the list gets the reply simultaneously. The most dangerous shape is `sender@legit.com, attacker@harvester.xyz` where one address matches the From domain, hiding the attack from single-address Reply-To checks that only inspect the first address. Detection counts `@` symbols; two or more means multi-address.
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 2,143+ 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.
