-The MTA service provides:
-- Complete SMTP server for receiving emails
-- DKIM signing and verification
-- SPF and DMARC support
-- DNS record management
-- Retry logic with queue processing
-- TLS encryption
+#### Key Features
 
-Here's how to use the MTA service:
+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
+  - **MTA Mode**: Full Mail Transfer Agent capabilities
+  - **Process Mode**: Store-and-forward with content scanning
+- **Unified Configuration**: Single configuration interface for all email handling
+- **Shared Infrastructure**: Use same ports (25, 587, 465) for all email handling
+- **Complete SMTP Server**: Receive emails with TLS and authentication support
+- **DKIM, SPF, DMARC**: Full email authentication standard support
+- **Content Scanning**: Check for spam, viruses, and other threats
+- **Advanced Delivery Management**: Queue, retry, and track delivery status
+
+#### Using the Consolidated Email System
+
+Here's how to use the consolidated email system:
 
 ```ts
-import { MtaService, Email } from '@serve.zone/platformservice';
+import { DcRouter, IEmailConfig, EmailProcessingMode } from '@serve.zone/platformservice';
+
+async function setupEmailHandling() {
+  // Configure the email handling system
+  const dcRouter = new DcRouter({
+    emailConfig: {
+      ports: [25, 587, 465],
+      hostname: 'mail.example.com',
+      
+      // TLS configuration
+      tls: {
+        certPath: '/path/to/cert.pem',
+        keyPath: '/path/to/key.pem'
+      },
+      
+      // Default handling for unmatched domains
+      defaultMode: 'forward' as EmailProcessingMode,
+      defaultServer: 'fallback.mail.example.com',

+      
+      // Pattern-based routing rules
+      domainRules: [
+        {

+
+#### Using the MTA Service Directly
+
+You can still use the MTA service directly for more granular control with our new modular directory structure:
