+# Implementation Hints and Learnings
+
+## SmartProxy Usage
+
+### New Route-Based Architecture (v18+)
+- SmartProxy now uses a route-based configuration system
+- Routes define match criteria and actions instead of simple port-to-port forwarding
+- All traffic types (HTTP, HTTPS, TCP, WebSocket) are configured through routes
+
+```typescript
+// NEW: Route-based SmartProxy configuration
+const smartProxy = new plugins.smartproxy.SmartProxy({
+  routes: [
+    {
+      name: 'https-traffic',
+      match: {
+        ports: 443,
+        domains: ['example.com', '*.example.com']
+      },
+      action: {
+        type: 'forward',
+        target: {
+          host: 'backend.server.com',
+          port: 8080
+        }
+      },
+      tls: {
+        mode: 'terminate',
+        certificate: 'auto'
+      }
+    }
+  ],
+  defaults: {
+    target: {
+      host: 'fallback.server.com',
+      port: 8080
+    }
+  },
+  acme: {
+    accountEmail: 'admin@example.com',
+    enabled: true,
+    useProduction: true
+  }
+});
+```
+
+### Migration from Old to New
+```typescript
+// OLD configuration style (deprecated)
+{
+  fromPort: 443,
+  toPort: 8080,
+  targetIP: 'backend.server.com',
+  domainConfigs: [...]
+}
+
+// NEW route-based style
+{
+  routes: [{
+    name: 'main-route',
+    match: { ports: 443 },
+    action: {
+      type: 'forward',
+      target: { host: 'backend.server.com', port: 8080 }
+    }
+  }]
+}
+```
+
+### Direct Component Usage
+- Use SmartProxy components directly instead of creating your own wrappers
+- SmartProxy already includes Port80Handler and NetworkProxy functionality
+- When using SmartProxy, configure it directly rather than instantiating Port80Handler or NetworkProxy separately
+
+### Certificate Management
+- SmartProxy has built-in ACME certificate management
+- Configure it in the `acme` property of SmartProxy options
+- Use `accountEmail` (not `email`) for the ACME contact email
+- SmartProxy handles both HTTP-01 challenges and certificate application automatically
+
+## qenv Usage
+
+### Direct Usage
+- Use qenv directly instead of creating environment variable wrappers
+- Instantiate qenv with appropriate basePath and nogitPath:
+
+```typescript
+const qenv = new plugins.qenv.Qenv('./', '.nogit/');
+const value = await qenv.getEnvVarOnDemand('ENV_VAR_NAME');
+```
+
+## TypeScript Interfaces
+
+### SmartProxy Interfaces
+- Always check the interfaces from the node_modules to ensure correct property names
+- Important interfaces for the new architecture:
+  - `ISmartProxyOptions`: Main configuration with `routes` array
+  - `IRouteConfig`: Individual route configuration
+  - `IRouteMatch`: Match criteria for routes
+  - `IRouteTarget`: Target configuration for forwarding
+  - `IAcmeOptions`: ACME certificate configuration
+  - `TTlsMode`: TLS handling modes ('passthrough' | 'terminate' | 'terminate-and-reencrypt')
+
+### New Route Configuration
+```typescript
+interface IRouteConfig {
+  name: string;
+  match: {
+    ports: number | number[];
+    domains?: string | string[];
+    path?: string;
+    headers?: Record<string, string | RegExp>;
+  };
+  action: {
+    type: 'forward' | 'redirect' | 'block' | 'static';
+    target?: {
+      host: string | string[] | ((context) => string);
+      port: number | 'preserve' | ((context) => number);
+    };
+  };
+  tls?: {
+    mode: TTlsMode;
+    certificate?: 'auto' | { key: string; cert: string; };
+  };
+  security?: {
+    authentication?: IRouteAuthentication;
+    rateLimit?: IRouteRateLimit;
+    ipAllowList?: string[];
+    ipBlockList?: string[];
+  };
+}
+```
+
+### Required Properties
+- For `ISmartProxyOptions`, `routes` array is the main configuration
+- For `IAcmeOptions`, use `accountEmail` for the contact email
+- Routes must have `name`, `match`, and `action` properties
+
+## Testing
+
+### Test Structure
+- Follow the project's test structure, using `@push.rocks/tapbundle`
+- Use `expect(value).toEqual(expected)` for equality checks
+- Use `expect(value).toBeTruthy()` for boolean assertions
+
+```typescript
+tap.test('test description', async () => {
+  const result = someFunction();
+  expect(result.property).toEqual('expected value');
+  expect(result.valid).toBeTruthy();
+});
+```
+
+### Cleanup
+- Include a cleanup test to ensure proper test resource handling
+- Add a `stop` test to forcefully end the test when needed:
+
+```typescript
+tap.test('stop', async () => {
+  await tap.stopForcefully();
+});
+```
+
+## Architecture Principles
+
+### Simplicity
+- Prefer direct usage of libraries instead of creating wrappers
+- Don't reinvent functionality that already exists in dependencies
+- Keep interfaces clean and focused, avoiding unnecessary abstraction layers
+
+### Component Integration
+- Leverage built-in integrations between components (like SmartProxy's ACME handling)
+- Use parallel operations for performance (like in the `stop()` method)
+- Separate concerns clearly (HTTP handling vs. SMTP handling)
+
+## Email Integration with SmartProxy
+
+### Architecture
+- Email traffic is routed through SmartProxy using automatic route generation
+- Email server runs on internal ports and receives forwarded traffic from SmartProxy
+- SmartProxy handles external ports (25, 587, 465) and forwards to internal ports
+
+### Email Route Generation
+```typescript
+// Email configuration automatically generates SmartProxy routes
+emailConfig: {
+  ports: [25, 587, 465],
+  hostname: 'mail.example.com',
+  domainRules: [...]
+}
+
+// Generates routes like:
+{
+  name: 'smtp-route',
+  match: { ports: [25] },
+  action: {
+    type: 'forward',
+    target: { host: 'localhost', port: 10025 }
+  },
+  tls: { mode: 'passthrough' } // STARTTLS handled by email server
+}
+```
+
+### Port Mapping
+- External port 25 → Internal port 10025 (SMTP)
+- External port 587 → Internal port 10587 (Submission)
+- External port 465 → Internal port 10465 (SMTPS)
+
+### TLS Handling
+- Ports 25 and 587: Use 'passthrough' mode (STARTTLS handled by email server)
+- Port 465: Use 'terminate' mode (SmartProxy handles TLS termination)
+- Domain-specific TLS can be configured per email rule

-# Plan for Further Enhancing the Email Stack
+# Platform Service - SmartProxy Architecture Update Plan
 
-## Current State Analysis
+**Command to reread CLAUDE.md: `cat /home/philkunz/.claude/CLAUDE.md`**
 
-The platformservice now has a robust email system with:
-- Enhanced EmailValidator with comprehensive validation (format, MX, spam detection)
-- Improved TemplateManager with typed templates and variable substitution
-- Streamlined conversion between Email and Smartmail formats
-- Strong attachment handling
-- Comprehensive testing
+## Overview
 
-## Identified Enhancement Opportunities
+SmartProxy has undergone a major architectural update, moving from a direct port-to-port proxy configuration to a flexible route-based system. This plan outlines the necessary updates to integrate these changes into the platformservice while retaining all SmartProxy functionality.
 
-### 1. Performance Optimization
+## New SmartProxy Architecture
 
-- [x] Replace setTimeout-based DNS cache with proper LRU cache implementation
-- [x] Implement rate limiting for outbound emails
-- [ ] Add bulk email handling with batching capabilities
-- [ ] Optimize template rendering for high-volume scenarios
+### Previous Architecture (Legacy)
+```typescript
+// Old configuration style
+{
+  fromPort: 443,
+  toPort: 8080,
+  targetIP: 'backend.server.com',
+  sniEnabled: true,
+  domainConfigs: [
+    {
+      domain: 'example.com',
+      target: 'backend1.server.com',
+      port: 8081
+    }
+  ]
+}
+```
 
-### 2. Security Enhancements
+### New Architecture (Route-Based)
+```typescript
+// New configuration style - FULL SmartProxy functionality
+{
+  routes: [
+    {
+      name: 'https-traffic',
+      match: {
+        ports: 443,
+        domains: ['example.com', '*.example.com']
+      },
+      action: {
+        type: 'forward',
+        target: {
+          host: 'backend.server.com',
+          port: 8080
+        }
+      },
+      tls: {
+        mode: 'terminate',
+        certificate: 'auto'
+      }
+    }
+  ],
+  defaults: {
+    target: {
+      host: 'fallback.server.com',
+      port: 8080
+    },
+    security: {
+      ipAllowList: ['192.168.1.0/24'],
+      maxConnections: 1000
+    }
+  }
+}
+```
 
-- [x] Implement DMARC policy checking and enforcement
-- [x] Add SPF validation for incoming emails
-- [x] Enhance logging for security-related events
-- [x] Add IP reputation checking for inbound emails
-- [x] Implement content scanning for potentially malicious payloads
+## Integration Approach
 
-### 3. Deliverability Improvements
+### 1. Direct SmartProxy Configuration
 
-- [x] Implement bounce handling and feedback loop processing
-- [x] Add automated IP warmup capabilities
-- [x] Develop sender reputation monitoring
-- [ ] Create domain rotation for high-volume sending
+The DcRouter will expose the full SmartProxy configuration directly, with additional email integration that automatically adds email routes to SmartProxy:
 
-### 4. Advanced Templating
+```typescript
+export interface IDcRouterOptions {
+  /**
+   * Full SmartProxy configuration - ALL SmartProxy features available
+   * This handles HTTP/HTTPS and general TCP/SNI traffic
+   */
+  smartProxyConfig?: plugins.smartproxy.ISmartProxyOptions;
+  
+  /**
+   * Email configuration - automatically creates SmartProxy routes for email ports
+   */
+  emailConfig?: IEmailConfig;
+  
+  /**
+   * Additional configuration options
+   */
+  tls?: {
+    contactEmail: string;
+    domain?: string;
+    certPath?: string;
+    keyPath?: string;
+  };
+  
+  /**
+   * DNS server configuration
+   */
+  dnsServerConfig?: plugins.smartdns.IDnsServerOptions;
+}
+```
 
-- [ ] Add conditional logic in email templates
-- [ ] Support localization with i18n integration
-- [ ] Implement template versioning and A/B testing capabilities
-- [ ] Add rich media handling (responsive images, video thumbnails)
+### 2. Email Route Auto-Generation
 
-### 5. Analytics and Monitoring
+When email configuration is provided, DcRouter will automatically generate SmartProxy routes for email traffic:
 
-- [ ] Implement delivery tracking and reporting
-- [ ] Add open and click tracking
-- [ ] Create dashboards for email performance
-- [ ] Set up alerts for delivery issues
-- [ ] Add spam complaint monitoring
+```typescript
+private async setupSmartProxy() {
+  let routes: plugins.smartproxy.IRouteConfig[] = [];
+  let acmeConfig: plugins.smartproxy.IAcmeOptions | undefined;
+  
+  // If user provides full SmartProxy config, use it directly
+  if (this.options.smartProxyConfig) {
+    routes = this.options.smartProxyConfig.routes || [];
+    acmeConfig = this.options.smartProxyConfig.acme;
+  }
+  
+  // If email config exists, automatically add email routes
+  if (this.options.emailConfig) {
+    const emailRoutes = this.generateEmailRoutes(this.options.emailConfig);
+    routes = [...routes, ...emailRoutes];
+  }
+  
+  // Merge TLS/ACME configuration if provided at root level
+  if (this.options.tls && !acmeConfig) {

+### Example 2: Advanced SmartProxy Features with Email
+```typescript
+const dcRouter = new DcRouter({
+  smartProxyConfig: {
+    routes: [
+      // Custom API route with authentication
+      {
+        name: 'api-route',
+        match: {
+          ports: 443,
+          domains: 'api.example.com',
+          path: '/v1/*'
+        },
+        action: {
+          type: 'forward',
+          target: {
+            host: (context) => {
+              // Dynamic host selection based on context
+              return context.headers['x-api-version'] === 'v2' 
+                ? 'api-v2.backend.com' 
+                : 'api-v1.backend.com';
+            },
+            port: 9090
+          }
+        },
+        security: {
+          authentication: {
+            type: 'jwt',
+            jwtSecret: process.env.JWT_SECRET
+          },
+          rateLimit: {
+            maxRequestsPerMinute: 100,
+            maxRequestsPerSecond: 10
+          }
+        }
+      }
+    ],
+    // Advanced SmartProxy options
+    preserveSourceIP: true,
+    enableDetailedLogging: true,
+    maxConnectionsPerIP: 50,
+    connectionRateLimitPerMinute: 1000
+  },
+  
+  // Email automatically integrates with SmartProxy
+  emailConfig: {
+    ports: [25, 587, 465],
+    hostname: 'mail.example.com',
+    domainRules: []
+  }
+});
+```
 
-3. **Deliverability Improvements**
-   - Implemented bounce handling with detection and categorization of different bounce types
-   - Created suppression list management to prevent sending to known bad addresses
-   - Added exponential backoff retry strategy for soft bounces
-   - Implemented automated IP warmup capabilities:
-     - Created configurable warmup stages with progressive volume increases
-     - Added multiple allocation policies (balanced, round robin, dedicated domain)
-     - Implemented daily and hourly sending limits with tracking
-     - Added persistence for warmup state between service restarts
-   - Developed comprehensive sender reputation monitoring:
-     - Implemented tracking of key deliverability metrics (bounces, complaints, opens, etc.)
-     - Added reputation scoring with multiple weighted components
-     - Created blacklist monitoring integration
-     - Implemented trend analysis for early detection of reputation issues
-     - Added full event tracking for sent, delivered, bounced, and complaint events
+## Key Benefits
 
-### Next Steps
+1. **Full SmartProxy Power**: All SmartProxy features remain available
+2. **Automatic Email Integration**: Email ports are automatically routed through SmartProxy
+3. **Unified TLS Management**: SmartProxy handles all TLS termination and certificates
+4. **Flexible Configuration**: Mix custom SmartProxy routes with automatic email routes
+5. **Performance**: SmartProxy's efficient routing benefits email traffic too
 
-1. Continue with security enhancements:
-   - ✅ Added IP reputation checking for inbound emails with DNS blacklist integration and caching
-   - ✅ Implemented content scanning for potentially malicious payloads with pattern matching and threat scoring
-   
-2. Further deliverability improvements:
-   - ✅ Added automated IP warmup capabilities with configurable stages and allocation policies
-   - ✅ Developed sender reputation monitoring with bounce tracking and metric calculation
-   
-3. Implement analytics and monitoring to gain visibility into performance
+## Implementation Tasks
 
-Each enhancement is being implemented incrementally with comprehensive testing to ensure reliability and backward compatibility, while maintaining the clean separation of concerns established in the codebase.
+- [ ] Update DcRouter to preserve full SmartProxy configuration
+- [ ] Implement automatic email route generation
+- [ ] Configure email server to run on internal ports
+- [ ] Test integration between SmartProxy and email server
+- [ ] Update documentation with full SmartProxy examples
+- [ ] Create migration guide showing how to use new features
+- [ ] Test advanced SmartProxy features with email routing
+- [ ] Verify TLS handling for different email ports
+- [ ] Test domain-specific email routing through SmartProxy
 
-## Success Metrics
+## Notes
 
-- Improved deliverability rates (95%+ inbox placement)
-- Enhanced security with no vulnerabilities
-- Support for high volume sending (10,000+ emails per hour)
-- Rich analytics providing actionable insights
-- High template flexibility for marketing and transactional emails
+- SmartProxy acts as the single entry point for all traffic (HTTP, HTTPS, and email)
+- Email server runs on internal ports and receives forwarded traffic from SmartProxy
+- TLS termination is handled by SmartProxy where appropriate
+- STARTTLS for email is handled by the email server itself
+- All SmartProxy features (rate limiting, authentication, dynamic routing) are available
