+# Files That Can Be Safely Removed
+
+The following files can be safely removed from the project as their functionality has been migrated to the new UnifiedEmailServer implementation:
+
+## Already Deleted Files (Confirmed Safe to Remove)
+1. `/ts/platformservice.ts` - Platform service now uses UnifiedEmailServer instead
+2. `/ts/classes.platformservicedb.ts` - No longer needed with the new architecture
+3. `/ts/mail/delivery/classes.mta.patch.ts` - MTA patching no longer needed with UnifiedEmailServer
+4. `/ts/aibridge/classes.aibridge.ts` - AIBridge functionality not used in new design
+5. `/test/test.dcrouter.ts` - Test file for old DcRouter functionality
+
+## Additional Files to Remove
+1. `/ts/mail/delivery/classes.mta.ts` - MTA service replaced by UnifiedEmailServer
+2. `/ts/mail/delivery/classes.connector.mta.ts` - MTA connector replaced by direct UnifiedEmailServer integration
+3. `/ts/mail/services/classes.emailservice.old.ts` (if exists) - Any old email service implementations
+4. `/ts/mail/delivery/classes.mtaconfig.old.ts` (if exists) - Old MTA configuration files
+
+## Files to Keep with Reduced Functionality
+1. `/ts/mail/delivery/classes.mta.config.ts` - Needed for configuration, but can be simplified
+2. `/ts/mail/delivery/classes.emailsendjob.ts` - Used by the delivery system, but could be simplified
+
+## Dependencies to Update
+1. Remove references to MtaService in `/ts/mail/index.ts`
+2. Update imports in `/ts/mail/services/classes.emailservice.ts` to remove MtaService dependencies
+
+## Notes
+- The UnifiedEmailServer now handles all the functionality previously provided by MtaService
+- Integration between components has been simplified to use the UnifiedEmailServer directly
+- References to the MtaService in other files should be updated to use UnifiedEmailServer instead

+# DCRouter Email Configuration Example
+
+This document provides a comprehensive example of configuring the UnifiedEmailServer in DCRouter for various email routing scenarios.
+
+## Basic Configuration
+
+Here's a complete example of a email configuration for the UnifiedEmailServer:
+
+```typescript
+import { IEmailConfig, EmailProcessingMode, IDomainRule } from './ts/config/email.config.js';
+
+const emailConfig: IEmailConfig = {
+ // Basic server settings
+ useEmail: true,
+ behindSmartProxy: false,
+ hostname: "mail.example.com",
+ ports: [25, 587, 465],
+
+ // Default processing settings
+ defaultMode: "forward" as EmailProcessingMode,
+ defaultServer: "smtp.internal-relay.example.com",
+ defaultPort: 25,
+ defaultTls: true,
+
+ // TLS configuration
+ tls: {
+ certPath: "/path/to/tls/certificate.pem",
+ keyPath: "/path/to/tls/key.pem",
+ caPath: "/path/to/tls/ca.pem",
+ minVersion: "TLSv1.2",
+ ciphers: "HIGH:!aNULL:!MD5:!RC4"
+ },
+
+ // Email size and connection limits
+ maxMessageSize: 25 * 1024 * 1024, // 25MB
+
+ // Authentication settings
+ auth: {
+ required: true,
+ methods: ["PLAIN", "LOGIN"],
+ users: [
+ { username: "user1", password: "securepassword1" },
+ { username: "user2", password: "securepassword2" }
+ ]
+ },
+
+ // Domain routing rules
+ domainRules: [
+ // Process emails for your primary domain via MTA
+ {
+ pattern: "*@example.com",
+ mode: "mta" as EmailProcessingMode,
+ mtaOptions: {
+ domain: "example.com",
+ dkimSign: true,
+ dkimOptions: {
+ domainName: "example.com",
+ keySelector: "mail"
+ }
+ }
+ },
+
+ // Forward support emails to help desk
+ {
+ pattern: "*@support.example.com",
+ mode: "forward" as EmailProcessingMode,
+ target: {
+ server: "helpdesk.example.com",
+ port: 25,
+ useTls: true
+ }
+ },
+
+ // Scan marketing emails for content and attachments
+ {
+ pattern: "*@marketing.example.com",
+ mode: "process" as EmailProcessingMode,
+ contentScanning: true,
+ scanners: [
+ {
+ type: "attachment",
+ action: "reject",
+ blockedExtensions: [".exe", ".zip", ".js", ".vbs", ".bat"]
+ },
+ {
+ type: "spam",
+ threshold: 5.0,
+ action: "tag"
+ }
+ ],
+ transformations: [
+ {
+ type: "addHeader",
+ header: "X-Scanned-By",
+ value: "DCRouter Content Scanner"
+ }
+ ]
+ },
+
+ // Forward all other emails to a backup server
+ {
+ pattern: "*@*",
+ mode: "forward" as EmailProcessingMode,
+ target: {
+ server: "backup-smtp.example.com",
+ port: 587,
+ useTls: true
+ }
+ }
+ ],
+
+ // Queue configuration
+ queue: {
+ storageType: "memory",
+ ttl: 86400000, // 24 hours
+ maxItems: 10000,
+ checkInterval: 60000 // 1 minute
+ },
+
+ // Template configuration
+ templateConfig: {
+ from: "noreply@example.com",
+ replyTo: "support@example.com",
+ footerHtml: "This is an automated message from Example Inc.
",
+ footerText: "This is an automated message from Example Inc."
+ },
+
+ // IP warmup configuration
+ serverConfig: {
+ delivery: {
+ concurrency: 10,
+ rateLimit: {
+ rate: 100,
+ interval: 60000 // 1 minute
+ },
+ retries: {
+ max: 3,
+ delay: 300000, // 5 minutes
+ useBackoff: true
+ }
+ },
+ security: {
+ useDkim: true,
+ verifyDkim: true,
+ verifySpf: true,
+ verifyDmarc: true,
+ enforceDmarc: true,
+ useTls: true,
+ requireValidCerts: true,
+ securityLogLevel: "info",
+ checkIPReputation: true,
+ scanContent: true,
+ maliciousContentAction: "tag",
+ threatScoreThreshold: 7.0
+ }
+ }
+};
+```
+
+## Initializing the UnifiedEmailServer
+
+Here's how to initialize the UnifiedEmailServer with the configuration:
+
+```typescript
+import { UnifiedEmailServer, IUnifiedEmailServerOptions } from './ts/mail/routing/classes.unified.email.server.js';
+
+// Convert EmailConfig to UnifiedEmailServerOptions
+const serverOptions: IUnifiedEmailServerOptions = {
+ ports: emailConfig.ports || [25],
+ hostname: emailConfig.hostname || 'localhost',
+ banner: `${emailConfig.hostname} ESMTP DCRouter`,
+
+ // Authentication
+ auth: emailConfig.auth,
+
+ // TLS
+ tls: emailConfig.tls,
+
+ // Message limits
+ maxMessageSize: emailConfig.maxMessageSize || 10 * 1024 * 1024, // 10MB default
+ maxClients: 100,
+
+ // Domain routing
+ domainRules: emailConfig.domainRules || [],
+ defaultMode: emailConfig.defaultMode || 'forward',
+ defaultServer: emailConfig.defaultServer,
+ defaultPort: emailConfig.defaultPort,
+ defaultTls: emailConfig.defaultTls,
+
+ // Deliverability options
+ ipWarmupConfig: {
+ enabled: true,
+ ipAddresses: ['198.51.100.1', '198.51.100.2', '198.51.100.3'],
+ targetDomains: ['gmail.com', 'yahoo.com', 'outlook.com'],
+ allocationPolicy: 'balanced'
+ },
+
+ reputationMonitorConfig: {
+ enabled: true,
+ domains: ['example.com', 'marketing.example.com'],
+ alertThresholds: {
+ bounceRate: 0.05, // 5%
+ complaintRate: 0.001 // 0.1%
+ }
+ }
+};
+
+// Create and start the server
+const emailServer = new UnifiedEmailServer(serverOptions);
+emailServer.start().then(() => {
+ console.log('UnifiedEmailServer started successfully');
+}).catch((error) => {
+ console.error('Failed to start UnifiedEmailServer:', error);
+});
+```
+
+## Use Case Examples
+
+### 1. Forwarding Email Gateway (SMTP Proxy)
+
+Configure DCRouter to forward emails for specific domains to internal mail servers:
+
+```typescript
+const forwardingRules: IDomainRule[] = [
+ // Main corporate domain - forward to Exchange
+ {
+ pattern: "*@corp.example.com",
+ mode: "forward" as EmailProcessingMode,
+ target: {
+ server: "exchange.internal",
+ port: 25,
+ useTls: true
+ }
+ },
+ // Marketing domain - forward to Marketing mail server
+ {
+ pattern: "*@marketing.example.com",
+ mode: "forward" as EmailProcessingMode,
+ target: {
+ server: "marketing-mail.internal",
+ port: 25,
+ useTls: false
+ }
+ }
+];
+```
+
+### 2. Outbound MTA with DKIM Signing and IP Warmup
+
+Configure DCRouter as an outbound mail transfer agent with DKIM signing and IP warmup:
+
+```typescript
+// MTA configuration with DKIM signing
+const mtaRule: IDomainRule = {
+ pattern: "*@outbound.example.com",
+ mode: "mta" as EmailProcessingMode,
+ mtaOptions: {
+ domain: "outbound.example.com",
+ dkimSign: true,
+ dkimOptions: {
+ domainName: "outbound.example.com",
+ keySelector: "mail2023"
+ }
+ }
+};
+
+// IP Warmup configuration
+const ipWarmupConfig = {
+ enabled: true,
+ ipAddresses: ['203.0.113.1', '203.0.113.2'],
+ targetDomains: ['gmail.com', 'yahoo.com', 'hotmail.com', 'aol.com'],
+ allocationPolicy: 'progressive',
+ fallbackPercentage: 20
+};
+```
+
+### 3. Content Scanning and Security Gateway
+
+Configure DCRouter to scan emails for malicious content and enforce security policies:
+
+```typescript
+const securityRule: IDomainRule = {
+ pattern: "*@*",
+ mode: "process" as EmailProcessingMode,
+ contentScanning: true,
+ scanners: [
+ // Scan for malicious attachments
+ {
+ type: "attachment",
+ action: "reject",
+ blockedExtensions: [".exe", ".dll", ".bat", ".vbs", ".js", ".cmd", ".scr", ".com", ".pif"]
+ },
+ // Scan for spam
+ {
+ type: "spam",
+ threshold: 6.0,
+ action: "tag"
+ },
+ // Scan for viruses
+ {
+ type: "virus",
+ action: "reject"
+ }
+ ],
+ transformations: [
+ // Add scanning headers
+ {
+ type: "addHeader",
+ header: "X-Security-Scanned",
+ value: "DCRouter Security Gateway"
+ }
+ ]
+};
+
+// Configure security settings
+const securityConfig = {
+ useDkim: true,
+ verifyDkim: true,
+ verifySpf: true,
+ verifyDmarc: true,
+ enforceDmarc: true,
+ checkIPReputation: true,
+ scanContent: true,
+ maliciousContentAction: "quarantine",
+ threatScoreThreshold: 5.0,
+ rejectHighRiskIPs: true,
+ securityLogLevel: "warn"
+};
+```
+
+### 4. Multi-Tenant Email Server
+
+Configure DCRouter to handle emails for multiple domains with different processing rules:
+
+```typescript
+const multiTenantRules: IDomainRule[] = [
+ // Tenant 1: Process locally
+ {
+ pattern: "*@tenant1.example.org",
+ mode: "mta" as EmailProcessingMode,
+ mtaOptions: {
+ domain: "tenant1.example.org",
+ dkimSign: true,
+ dkimOptions: {
+ domainName: "tenant1.example.org",
+ keySelector: "t1mail"
+ }
+ }
+ },
+ // Tenant 2: Forward to their server
+ {
+ pattern: "*@tenant2.example.org",
+ mode: "forward" as EmailProcessingMode,
+ target: {
+ server: "mail.tenant2.com",
+ port: 587,
+ useTls: true
+ }
+ },
+ // Tenant 3: Process with content scanning
+ {
+ pattern: "*@tenant3.example.org",
+ mode: "process" as EmailProcessingMode,
+ contentScanning: true,
+ scanners: [
+ {
+ type: "attachment",
+ action: "tag",
+ blockedExtensions: [".zip", ".rar", ".7z"]
+ }
+ ]
+ }
+];
+```
+
+## Using the Bounce Management System
+
+DCRouter includes a sophisticated bounce management system. Here's how to use it:
+
+```typescript
+// Get an instance of the UnifiedEmailServer
+const emailServer = new UnifiedEmailServer(serverOptions);
+
+// Check if an email is on the suppression list
+const isSuppressed = emailServer.isEmailSuppressed('user@example.com');
+
+// Get suppression information
+const suppressionInfo = emailServer.getSuppressionInfo('user@example.com');
+if (suppressionInfo) {
+ console.log(`Suppressed due to: ${suppressionInfo.reason}`);
+ console.log(`Suppressed since: ${new Date(suppressionInfo.timestamp)}`);
+ if (suppressionInfo.expiresAt) {
+ console.log(`Suppression expires: ${new Date(suppressionInfo.expiresAt)}`);
+ } else {
+ console.log('Suppression is permanent');
+ }
+}
+
+// Add an email to the suppression list
+emailServer.addToSuppressionList(
+ 'problem-user@example.com',
+ 'Manual suppression due to user request',
+ Date.now() + (30 * 24 * 60 * 60 * 1000) // Expires in 30 days
+);
+
+// Remove an email from the suppression list
+emailServer.removeFromSuppressionList('reactivated-user@example.com');
+
+// Get all suppressed emails
+const suppressionList = emailServer.getSuppressionList();
+console.log(`There are ${suppressionList.length} suppressed email addresses`);
+```
+
+## Using the IP Warmup System
+
+DCRouter's IP warmup system helps gradually build sender reputation for new IP addresses:
+
+```typescript
+// Add a new IP to warmup
+emailServer.addIPToWarmup('198.51.100.4');
+
+// Get warmup status for all IPs
+const warmupStatus = emailServer.getIPWarmupStatus();
+console.log('IP Warmup Status:', warmupStatus);
+
+// Get warmup status for a specific IP
+const specificIPStatus = emailServer.getIPWarmupStatus('198.51.100.1');
+console.log(`Warmup day: ${specificIPStatus.day}`);
+console.log(`Daily limit: ${specificIPStatus.dailyLimit}`);
+console.log(`Emails sent today: ${specificIPStatus.sentToday}`);
+
+// Update IP metrics based on feedback from mailbox providers
+emailServer.updateIPWarmupMetrics('198.51.100.1', {
+ openRate: 0.25, // 25% open rate
+ bounceRate: 0.02, // 2% bounce rate
+ complaintRate: 0.001 // 0.1% complaint rate
+});
+
+// Check if an IP can send more emails today
+if (emailServer.canIPSendMoreToday('198.51.100.1')) {
+ console.log('IP can send more emails today');
+} else {
+ console.log('IP has reached its daily sending limit');
+}
+
+// Change the IP allocation policy
+emailServer.setIPAllocationPolicy('volume-based');
+```
+
+## Sender Reputation Monitoring
+
+Monitor and manage your domain reputation with these features:
+
+```typescript
+// Add a domain to monitoring
+emailServer.addDomainToMonitoring('newdomain.example.com');
+
+// Get reputation data for a specific domain
+const reputationData = emailServer.getDomainReputationData('example.com');
+console.log(`Reputation score: ${reputationData.score}`);
+console.log(`Bounce rate: ${reputationData.bounceRate}`);
+console.log(`Complaint rate: ${reputationData.complaintRate}`);
+
+// Get a summary of all domains
+const summary = emailServer.getReputationSummary();
+console.log('Domain reputation summary:', summary);
+
+// Record a custom engagement event
+emailServer.recordReputationEvent('example.com', {
+ type: 'open',
+ count: 15
+});
+```
+
+## Updating Configuration at Runtime
+
+DCRouter allows updating configurations dynamically without restarting:
+
+```typescript
+// Update domain rules
+const newRules: IDomainRule[] = [
+ // New rules here
+];
+emailServer.updateDomainRules(newRules);
+
+// Update server options
+emailServer.updateOptions({
+ maxMessageSize: 50 * 1024 * 1024, // 50MB
+ maxClients: 200,
+ defaultServer: 'new-relay.example.com'
+});
+```
+
+This example configuration covers a wide range of use cases from simple forwarding to advanced security scanning, IP warmup, and reputation management, showcasing DCRouter's versatility as an email routing and processing solution.

-# Platform Service - SmartProxy Architecture Update Plan
-
-**Command to reread CLAUDE.md: `cat /home/philkunz/.claude/CLAUDE.md`**
-
-## Overview
-
-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.
-
-## New SmartProxy Architecture
-
-### 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
- }
- ]
-}
-```
-
-### 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
- }
- }
-}
-```
-
-## Integration Approach
-
-### 1. Direct SmartProxy Configuration
-
-The DcRouter will expose the full SmartProxy configuration directly, with additional email integration that automatically adds email routes to SmartProxy:
-
-```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;
-}
-```
-
-### 2. Email Route Auto-Generation
-
-When email configuration is provided, DcRouter will automatically generate SmartProxy routes for email traffic:
-
-```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) {
- acmeConfig = {
- accountEmail: this.options.tls.contactEmail,
- enabled: true,
- useProduction: true,
- autoRenew: true,
- renewThresholdDays: 30
- };
- }
-
- // Initialize SmartProxy with combined configuration
- this.smartProxy = new plugins.smartproxy.SmartProxy({
- ...this.options.smartProxyConfig,
- routes,
- acme: acmeConfig
- });
-
- await this.smartProxy.start();
- logger.info('SmartProxy started with route-based configuration');
-}
-
-private generateEmailRoutes(emailConfig: IEmailConfig): plugins.smartproxy.IRouteConfig[] {
- const emailRoutes: plugins.smartproxy.IRouteConfig[] = [];
-
- // Create routes for each email port
- for (const port of emailConfig.ports) {
- // Handle different email ports differently
- switch (port) {
- case 25: // SMTP
- emailRoutes.push({
- name: 'smtp-route',
- match: {
- ports: [25]
- },
- action: {
- type: 'forward',
- target: {
- host: 'localhost', // Forward to internal email server
- port: 10025 // Internal email server port
- }
- },
- // No TLS termination for port 25 (STARTTLS handled by email server)
- tls: {
- mode: 'passthrough'
- }
- });
- break;
-
- case 587: // Submission
- emailRoutes.push({
- name: 'submission-route',
- match: {
- ports: [587]
- },
- action: {
- type: 'forward',
- target: {
- host: 'localhost',
- port: 10587
- }
- },
- tls: {
- mode: 'passthrough' // STARTTLS handled by email server
- }
- });
- break;
-
- case 465: // SMTPS
- emailRoutes.push({
- name: 'smtps-route',
- match: {
- ports: [465]
- },
- action: {
- type: 'forward',
- target: {
- host: 'localhost',
- port: 10465
- }
- },
- tls: {
- mode: 'terminate', // Terminate TLS and re-encrypt to email server
- certificate: 'auto'
- }
- });
- break;
- }
- }
-
- // Add domain-specific email routes if configured
- if (emailConfig.domainRules) {
- for (const rule of emailConfig.domainRules) {
- // Extract domain from pattern (e.g., "*@example.com" -> "example.com")
- const domain = rule.pattern.split('@')[1];
-
- if (domain && rule.mode === 'forward' && rule.target) {
- emailRoutes.push({
- name: `email-forward-${domain}`,
- match: {
- ports: emailConfig.ports,
- domains: [domain]
- },
- action: {
- type: 'forward',
- target: {
- host: rule.target.server,
- port: rule.target.port || 25
- }
- },
- tls: {
- mode: rule.target.useTls ? 'terminate-and-reencrypt' : 'passthrough'
- }
- });
- }
- }
- }
-
- return emailRoutes;
-}
-```
-
-### 3. Email Server Integration
-
-The email server will run on internal ports and receive traffic from SmartProxy:
-
-```typescript
-private async setupUnifiedEmailHandling() {
- if (!this.options.emailConfig) {
- logger.info('No email configuration provided');
- return;
- }
-
- const emailConfig = this.options.emailConfig;
-
- // Map external ports to internal ports
- const portMapping = {
- 25: 10025, // SMTP
- 587: 10587, // Submission
- 465: 10465 // SMTPS
- };
-
- // Create internal email server configuration
- const internalEmailConfig: IEmailConfig = {
- ...emailConfig,
- ports: emailConfig.ports.map(port => portMapping[port] || port + 10000),
- hostname: 'localhost' // Listen on localhost for SmartProxy forwarding
- };
-
- // Initialize email components with internal configuration
- this.domainRouter = new DomainRouter({
- domainRules: emailConfig.domainRules,
- defaultMode: emailConfig.defaultMode,
- defaultServer: emailConfig.defaultServer,
- defaultPort: emailConfig.defaultPort,
- defaultTls: emailConfig.defaultTls
- });
-
- this.unifiedEmailServer = new UnifiedEmailServer({
- ...internalEmailConfig,
- domainRouter: this.domainRouter
- });
-
- await this.unifiedEmailServer.start();
- logger.info('Unified email server started on internal ports');
-}
-```
-
-## Usage Examples
-
-### Example 1: Combined HTTP and Email Configuration
-```typescript
-const dcRouter = new DcRouter({
- // Full SmartProxy configuration for HTTP/HTTPS
- smartProxyConfig: {
- routes: [
- {
- name: 'web-traffic',
- match: {
- ports: [80, 443],
- domains: ['www.example.com']
- },
- action: {
- type: 'forward',
- target: {
- host: 'web-backend.example.com',
- port: 8080
- }
- },
- tls: {
- mode: 'terminate',
- certificate: 'auto'
- }
- }
- ],
- acme: {
- accountEmail: 'admin@example.com',
- enabled: true,
- useProduction: true
- }
- },
-
- // Email configuration - automatically creates SmartProxy routes
- emailConfig: {
- ports: [25, 587, 465],
- hostname: 'mail.example.com',
- domainRules: [
- {
- pattern: '*@example.com',
- mode: 'mta',
- mtaOptions: {
- dkimSign: true,
- dkimOptions: {
- domainName: 'example.com',
- keySelector: 'mail',

-### 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: []
- }
-});
-```
-
-## Key Benefits
-
-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
-
-## Implementation Tasks
-
-- [ ] 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
-
-## Notes
-
-- 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
