High-priority flag set from a free webmail account — no legit business mails from gmail.com with X-Priority: 1
fake-high-priority-from-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
The email has `X-Priority: 1` or `Importance: high` set in the headers AND the From address is on a free webmail domain (gmail.com, yahoo.com, outlook.com, hotmail.com, protonmail.com, etc.). Neither condition is problematic on its own — some legitimate users mark urgent personal emails as high priority, and everyone has a gmail address. But the combination is attack-shaped: no legitimate transactional or marketing system operates from a free webmail account AND sets the "High" priority flag. Real businesses use dedicated mailer infrastructure on their own domain; real individuals sending urgent personal mail rarely bother with the X-Priority header at all (Outlook / Thunderbird expose it but Gmail doesn't, so most modern senders never touch it). A free-webmail sender deliberately setting high priority is trying to manipulate the recipient's attention via an emotional "this looks important" shortcut. Weight: +3 (compound with the +1 base `fake-high-priority` signal for a total of +4 on this shape).
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.
