2.8.4

Clarify that the platform now organizes email functionality into distinct directories (mail/core, mail/delivery, mail/routing, mail/security, mail/services) and update the diagram and key features list accordingly. Adjust code examples to reflect explicit module imports and the use of SzPlatformService.

+
+## 2025-05-08 - 2.8.2 - fix(tests)
+Fix outdated import paths in test files for dcrouter and ratelimiter modules
+
+- Updated dcrouter import from '../ts/dcrouter/index.js' to '../ts/classes.dcrouter.js'
+- Updated ratelimiter import from '../ts/mta/classes.ratelimiter.js' to '../ts/mail/delivery/classes.ratelimiter.js'
+
+## 2025-05-08 - 2.8.1 - fix(readme)
+Update readme with consolidated email system improvements and modular directory structure
+
+Clarify that the platform now organizes email functionality into distinct directories (mail/core, mail/delivery, mail/routing, mail/security, mail/services) and update the diagram and key features list accordingly. Adjust code examples to reflect explicit module imports and the use of SzPlatformService.
+
+- Changed description of consolidated email configuration to include 'streamlined directory structure'.
+- Updated mermaid diagram to show 'Mail System Structure' with separate components for core, delivery, routing, security, and services.
+- Modified key features list to document modular directory structure.
+- Revised code sample imports to use explicit paths and SzPlatformService.
+
 ## 2025-05-08 - 2.8.0 - feat(docs)

 #### Key Features
 
 The email handling system provides:
+- **Modular Directory Structure**: Clean organization with clear separation of concerns:
+  - **mail/core**: Core email models and basic functionality (Email, BounceManager, etc.)
+  - **mail/delivery**: Email delivery mechanisms (MTA, SMTP server, rate limiting)
+  - **mail/routing**: DNS and domain routing capabilities
+  - **mail/security**: Authentication and security features (DKIM, SPF, DMARC)
+  - **mail/services**: High-level services and API interfaces
 - **Pattern-based Routing**: Route emails based on glob patterns like `*@domain.com` or `*@*.domain.com`
 - **Multi-Modal Processing**: Handle different email domains with different processing modes:
   - **Forward Mode**: SMTP forwarding to other servers
