 # Changelog
 
+## 2025-05-08 - 2.7.0 - feat(dcrouter)
+Implement unified email configuration with pattern‐based routing and consolidated email processing. Migrate SMTP forwarding and store‐and‐forward into a single, configuration-driven system that supports glob pattern matching in domain rules.
+
+- Introduced IEmailConfig interface to consolidate MTA, forwarding, and processing settings.
+- Added pattern-based domain routing with glob patterns (e.g., '*@example.com', '*@*.example.net').
+- Reworked DcRouter integration to expose unified email handling and updated readme.plan.md and changelog.md accordingly.
+- Removed deprecated SMTP forwarding components in favor of the consolidated approach.
+
+## 2025-05-08 - 2.7.0 - feat(dcrouter)
+Implement consolidated email configuration with pattern-based routing
+
+- Added new pattern-based email routing with glob patterns (e.g., `*@task.vc`, `*@*.example.net`)
+- Consolidated all email functionality (MTA, forwarding, processing) under a unified `emailConfig` interface
+- Implemented domain router with pattern specificity calculation for most accurate matching
+- Removed deprecated components (SMTP forwarding, Store-and-Forward) in favor of the unified approach
+- Updated DcRouter tests to use the new consolidated email configuration pattern
+- Enhanced inline documentation with detailed interface definitions and configuration examples
+- Updated implementation plan with comprehensive component designs for the unified email system
+
+## 2025-05-07 - 2.6.0 - feat(dcrouter)
+Implement integrated DcRouter with comprehensive SmartProxy configuration, enhanced SMTP processing, and robust store‐and‐forward email routing
+
+- Marked completion of tasks in readme.plan.md with [x] flags for SMTP server setup, email processing pipeline, queue management, and delivery system.
+- Reworked DcRouter to use direct SmartProxy configuration, separating smtpConfig and smtpForwarding approaches.
+- Added new components for delivery queue and delivery system with persistent storage support.
+- Improved SMTP server implementation with TLS support, event handlers for connection, authentication, sender/recipient validation, and data processing.
+- Refined domain-based routing and transformation logic in EmailProcessor with metrics and logging.
+- Updated exported modules in dcrouter index to include SMTP store‐and‐forward components.
+- Enhanced inline documentation and code comments for configuration interfaces and integration details.
+
+## 2025-05-07 - 2.5.0 - feat(dcrouter)
+Enhance DcRouter configuration and update documentation
+
+- Added new implementation hints (readme.hints.md) and planning documentation (readme.plan.md) outlining removal of SzPlatformService dependency and improvements in SMTP forwarding, domain routing, and certificate management.
+- Introduced new interfaces: ISmtpForwardingConfig and IDomainRoutingConfig for precise SMTP and HTTP domain routing configuration.
+- Refactored DcRouter classes to support direct integration with SmartProxy and enhanced MTA functionality, including SMTP port configuration and improved TLS handling.
+- Updated supporting modules such as SmtpPortConfig and EmailDomainRouter to provide better routing and security options.
+- Enhanced test coverage across dcrouter, rate limiter, IP warmup manager, and email authentication, ensuring backward compatibility and improved quality.
+
 ## 2025-05-07 - 2.4.2 - fix(tests)
 Update test assertions and singleton instance references in DMARC, integration, and IP warmup manager tests

+# Implementation Hints and Learnings
+
+## SmartProxy Usage
+
+### 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
+
+```typescript
+// PREFERRED: Use SmartProxy with built-in ACME support
+const smartProxy = new plugins.smartproxy.SmartProxy({
+  fromPort: 443,
+  toPort: targetPort,
+  targetIP: targetServer,
+  sniEnabled: true,
+  acme: {
+    port: 80,
+    enabled: true,
+    autoRenew: true,
+    useProduction: true,
+    renewThresholdDays: 30,
+    accountEmail: contactEmail
+  },
+  globalPortRanges: [{ from: 443, to: 443 }],
+  domainConfigs: [/* domain configurations */]
+});
+```
+
+### 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:
+  - `ISmartProxyOptions`: Main configuration for SmartProxy
+  - `IAcmeOptions`: ACME certificate configuration
+  - `IDomainConfig`: Domain-specific configuration
+
+### Required Properties
+- Remember to include all required properties in your interface implementations
+- For `ISmartProxyOptions`, `globalPortRanges` is required
+- For `IAcmeOptions`, use `accountEmail` for the contact email
+
+## 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)
