v1.3

[1.3.0] - 2026-01-24

Added

• Email Health Grading - Automatic scoring (A-F) of email infrastructure security. Analyzes MX redundancy, SPF strictness, DKIM presence, and DMARC policies with actionable recommendations.
• SPF Visualizer - Deep analysis of Sender Policy Framework records. Breaks down mechanisms, identifies third-party providers, checks qualifiers, and counts DNS lookups against the RFC limit of 10.
• Reverse DNS Verification - Performs Forward-Confirmed Reverse DNS (FCrDNS) checks on resolved IP addresses to validate server identity (PTR record matching).
• Advanced History Filtering - Filter the scan log by Domain Existence, detected Platform (CMS), and Scan Frequency.
• Expanded DKIM Detection - Added signatures for 50+ major email providers including Google Workspace, Microsoft 365, SendGrid, Mailchimp, Postmark, and Zendesk.

Changed

• Engine Architecture - Unified the DNS lookup logic into a single robust pipeline for both CLI and Web interfaces, improving consistency.
• Cache System - Implemented background cache regeneration to seamlessly upgrade legacy scan data to the latest format without blocking the UI.
