From display name is only digits / punctuation — spam fingerprint

from-display-name-only-digits

What this tier means

Warning signal — bulk / marketing / mild spam. Contributes to the trash score but is not by itself sufficient.

How Gorganizer detects this

The From header's display name contains only digits / punctuation / whitespace — no letters at all. Spam pattern: `From: "12345" <x@y.z>` or fake phone-number displays like `"888-777-6666" <support@random>`. Spammers use numeric display names to evade keyword-based display-name filters and to impersonate SMS short codes or corporate support lines. Legitimate senders always have at least one letter in their display name — company names, personal names, and brand names in every language all contain letters (including CJK, Cyrillic, Arabic, etc. which count as letters under Unicode `\p{L}`). A purely numeric display name is either a misconfigured mailer (rare) or a spammer.

False-positive guard

Every signal in Gorganizer feeds a multi-module score — never a sole verdict. This is a warning-tier signal — bulk / marketing / mild spam. It contributes to the trash score but never triggers deletion on its own. Gorganizer requires multiple signals + a margin over the safety floor before any email is moved to trash.

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.
