+# 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: {

+      { 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"

+      contentScanning: true,
+      scanners: [
+        {
+          type: "attachment",
+          action: "reject",
+          blockedExtensions: [".exe", ".zip", ".js", ".vbs", ".bat"]
+        },
+        {

+          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

+    },
+    security: {
+      useDkim: true,
+      verifyDkim: true,
+      verifySpf: true,
+      verifyDmarc: true,
+      enforceDmarc: 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

-
-### 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',
-            privateKey: '...'
-          }
-        }
-      }
-    ],
-    defaultMode: 'forward',
-    defaultServer: 'backup-mail.example.com'
-  }
-});
-```
-
-### 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
