Large gap between Received: header timestamps (relay delay)
received-header-timestamp-gap
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 gap between two consecutive Received: header timestamps exceeds 2 hours. Legitimate email flows through mail servers in seconds to minutes — a relay delay of 2+ hours between hops indicates a queued botnet sending node, a spam staging server, or a deliberate timing manipulation to confuse analysis tools. The timestamps are extracted from the semicolon-delimited date fragment of each Received: hop (e.g. "; Tue, 14 Apr 2026 12:00:00 +0000"), sorted oldest-first, and the maximum consecutive gap is compared against the 2-hour threshold. Requires at least 2 parseable timestamps; malformed or absent Received: headers silently skip. Score: +2 trash.
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.
