Mail Threat Zero Email Flow Diagram

Layer 1: Connection Filtering

Network-level protection blocks threats before processing. Includes RBL/DNSBL checking, IP reputation analysis, GeoIP filtering, rate limiting, and greylisting to stop malicious connections at the entry point.

Layer 2: Authentication

Identity verification prevents spoofing and phishing. SPF verification ensures authorized sending servers, DKIM validates message integrity, and DMARC enforces domain policies for authentic sender validation.

Layer 3: Virus Detection

Malware and virus scanning protects against malicious payloads. ClamAV (official & unofficial signatures), Maldet for Linux threats, and deep attachment scanning catch trojans, worms, and ransomware before delivery.

Layer 4: Spam Filtering

Advanced spam detection blocks unwanted bulk email. SpamAssassin with 550+ rules, Rspamd with machine learning, Bayesian filtering, and URL/link checking identify and quarantine spam and phishing attempts.

Layer 5: AI Analysis (MTZ AI Protocol)

Optional AI-powered detection catches sophisticated threats using the MTZ AI Protocol. Activated when earlier layers need deeper analysis (score < 10). Choose from GPT-4, Claude 3.5 Sonnet, Gemini Pro, or other models for BEC and advanced phishing detection.

Final Decision & Delivery

Intelligent routing ensures safe delivery. Clean emails reach your server instantly, suspicious messages are quarantined for review, and malicious emails are rejected. Only validated, safe emails reach your users' inboxes.
