All Smartmail usage has been eliminated. - -### Key Changes -1. **Email Class Enhanced** - Added compatibility methods: `getSubject()`, `getBody(isHtml)`, `getFrom()` -2. **BounceManager** - Now accepts `Email` objects directly -3. **TemplateManager** - Returns `Email` objects instead of Smartmail -4. **EmailService** - `sendEmail()` accepts `Email` objects -5. **RuleManager** - Uses `SmartRule` instead of `SmartRule` -6. **ApiManager** - Creates `Email` objects for API requests - -### Benefits -- No more Email ↔ Smartmail conversions -- Consistent API throughout (`email.subject` not `smartmail.options.subject`) -- Better performance (no conversion overhead) -- Simpler, more maintainable code - -### Usage Pattern -```typescript -// Create email -const email = new Email({ - from: 'sender@example.com', - to: 'recipient@example.com', - subject: 'Hello', - text: 'World' -}); - -// Pass directly through system -await bounceManager.processBounceEmail(email); -await templateManager.prepareEmail(templateId, context); -await emailService.sendEmail(email); -``` - -## Email Class Design Pattern (2025-05-27) - -### Three-Interface Pattern for Email -The Email system uses three distinct interfaces for clarity and type safety: - -1. **IEmailOptions** - The flexible input interface: - ```typescript - interface IEmailOptions { - to: string | string[]; // Flexible: single or array - cc?: string | string[]; // Optional - attachments?: IAttachment[]; // Optional - skipAdvancedValidation?: boolean; // Constructor-only option - } - ``` - - Used as constructor parameter - - Allows flexible input formats - - Has constructor-only options (like skipAdvancedValidation) - -2. **INormalizedEmail** - The normalized runtime interface: - ```typescript - interface INormalizedEmail { - to: string[]; // Always an array - cc: string[]; // Always an array (empty if not provided) - attachments: IAttachment[]; // Always an array (empty if not provided) - mightBeSpam: boolean; // Always has a value (defaults to false) - } - ``` - - Represents the guaranteed internal structure - - No optional arrays - everything has a default - - Email class implements this interface - -3. **Email class** - The implementation: - ```typescript - export class Email implements INormalizedEmail { - // All INormalizedEmail properties - to: string[]; - cc: string[]; - // ... etc - - // Additional runtime properties - private messageId: string; - private envelopeFrom: string; - } - ``` - - Implements INormalizedEmail - - Adds behavior methods and computed properties - - Handles validation and normalization - -### Benefits of This Pattern: -- **Type Safety**: Email class explicitly implements INormalizedEmail -- **Clear Contracts**: Input vs. runtime structure is explicit -- **Flexibility**: IEmailOptions allows various input formats -- **Consistency**: INormalizedEmail guarantees structure -- **Validation**: Constructor validates and normalizes - -### Usage: -```typescript -// Input with flexible options -const options: IEmailOptions = { - from: 'sender@example.com', - to: 'recipient@example.com', // Single string - subject: 'Hello', - text: 'World' -}; - -// Creates normalized Email instance -const email = new Email(options); - -// email.to is guaranteed to be string[] -email.to.forEach(recipient => { - // No need to check if it's an array -}); - -// Convert back to options format -const optionsAgain = email.toEmailOptions(); -``` - -### Template Email Creation (2025-05-27) -The Email class now supports template creation without recipients: -- IEmailOptions 'to' field is now optional (for templates) -- Email constructor allows creation without recipients -- Recipients are added later when the email is actually sent - -```typescript -// Template creation (no recipients) -const emailOptions: IEmailOptions = { - from: 'noreply@example.com', - subject: 'Welcome {{name}}', - text: 'Hello {{name}}!', - // 'to' is omitted for templates - variables: { name: 'User' } -}; - -const templateEmail = new Email(emailOptions); -// templateEmail.to is an empty array [] - -// Later, when sending: -templateEmail.to = ['recipient@example.com']; -``` - -## Email Architecture Consolidation Completed (2025-05-27) - -### Summary -The email architecture consolidation has been fully completed. Contrary to the initial analysis, the architecture was already well-organized: - -1. **UnifiedEmailServer already contains all components** - No scattered components in DcRouter -2. **EmailSendJob already uses pooled SmtpClient** - No duplicate SMTP implementations -3. **setupUnifiedEmailHandling() is simple** - Only ~30 lines, not 150+ -4. **Connection pooling already implemented** - Via `getSmtpClient(host, port)` -5. **SmtpPortConfig doesn't exist** - No orphaned code found - -### Key Architecture Points -- DcRouter has single `emailServer?: UnifiedEmailServer` property -- All email functionality encapsulated in UnifiedEmailServer -- Dependency injection pattern used throughout (e.g., EmailSendJob receives UnifiedEmailServer reference) -- Pooled SMTP clients managed centrally in UnifiedEmailServer -- Clean separation of concerns between routing (DcRouter) and email handling (UnifiedEmailServer) - -## Email Router Architecture Decision (2025-05-28) - -### Single Router Class -- **Important**: We will have only ONE router class, not two -- The existing `DomainRouter` will be evolved into `EmailRouter` -- This avoids confusion and redundancy -- Use `git mv` to rename and preserve git history -- Extend it to support the new match/action pattern inspired by SmartProxy -- Maintain backward compatibility for legacy domain-based rules - -### Benefits of Single Router -- Clear, single source of truth for routing logic -- No confusion about which router to use -- Preserved git history and gradual migration path -- Supports all match criteria (not just domains) - -## Email Routing Architecture (2025-05-27) - -### Current Routing Capabilities -1. **Pattern-based routing** - DomainRouter matches email addresses against patterns -2. **Three processing modes**: - - `mta` - Programmatic processing with optional DKIM signing - - `process` - Store-and-forward with content scanning - - `forward` - Direct forwarding (NOT YET IMPLEMENTED) -3. **Default routing** - Fallback for unmatched patterns -4. **Basic caching** - LRU cache for routing decisions - -### Routing Flow -```typescript -// Current flow in UnifiedEmailServer.processEmailByMode() -1. Email arrives → DomainRouter.matchRule(recipient) -2. Apply matched rule or default -3. Process based on mode: - - mta: Apply DKIM, log, return - - process: Scan content, apply transformations, queue - - forward: ERROR - Not implemented -``` - -### Missing Routing Features -1. **No forwarding implementation** - Forward mode throws error -2. **Limited matching** - Only email address patterns, no regex -3. **No conditional routing** - Can't route based on subject, size, etc. -4. **No load balancing** - Single destination per rule -5. **No failover** - No backup routes -6. **Basic transformations** - Only header additions - -### Key Files for Routing -- `ts/mail/routing/classes.domain.router.ts` - Pattern matching engine -- `ts/mail/routing/classes.unified.email.server.ts` - processEmailByMode() -- `ts/mail/routing/classes.email.config.ts` - Rule interfaces -- `ts/mail/delivery/classes.delivery.system.ts` - Delivery execution - -## Configuration System Cleanup (2025-05-27) - COMPLETED - -### Overview -The `ts/config/` directory cleanup has been completed. Removed ~500+ lines of unused legacy configuration code. - -### Changes Made -✅ **Removed Files:** -- `base.config.ts` - All unused base interfaces -- `platform.config.ts` - Completely unused platform config -- `email.config.ts` - Deprecated email configuration -- `email.port.mapping.ts` - Unused port mapping utilities -- `schemas.ts` - Removed all schemas except SMS -- `sms.config.ts` - Moved to SMS module - -✅ **SMS Configuration Moved:** -- Created `ts/sms/config/sms.config.ts` - ISmsConfig interface -- Created `ts/sms/config/sms.schema.ts` - Validation schema -- Updated SmsService to import from new location - -✅ **Kept:** -- `validator.ts` - Generic validation utility (might move to utils later) -- `index.ts` - Now only exports ConfigValidator - -### Result -- Config directory now contains only 2 files (validator.ts, index.ts) -- SMS configuration is self-contained in SMS module -- All deprecated email configuration removed -- Build passes successfully - -## Per-Domain Rate Limiting (2025-05-29) - COMPLETED - -### Overview -Per-domain rate limiting has been implemented in the UnifiedRateLimiter. Each email domain can have its own rate limits that override global limits. - -### Implementation Details -1. **UnifiedRateLimiter Enhanced:** - - Added `domains` property to IHierarchicalRateLimits - - Added `domainCounters` Map for tracking domain-specific counters - - Added `checkDomainMessageLimit()` method - - Added `applyDomainLimits()`, `removeDomainLimits()`, `getDomainLimits()` methods - -2. **Domain Rate Limit Configuration:** - ```typescript - interface IEmailDomainConfig { - domain: string; - rateLimits?: { - outbound?: { - messagesPerMinute?: number; - messagesPerHour?: number; // Note: Hour/day limits need additional implementation - messagesPerDay?: number; - }; - inbound?: { - messagesPerMinute?: number; - connectionsPerIp?: number; - recipientsPerMessage?: number; - }; - }; - } - ``` - -3. **Automatic Application:** - - UnifiedEmailServer applies domain rate limits during startup - - `applyDomainRateLimits()` method converts domain config to rate limiter format - - Domain limits override pattern and global limits - -4. **Usage Pattern:** - ```typescript - // Domain configuration with rate limits - { - domain: 'high-volume.com', - dnsMode: 'internal-dns', - rateLimits: { - outbound: { - messagesPerMinute: 200 // Higher than global limit - }, - inbound: { - recipientsPerMessage: 100 // Higher recipient limit - } - } - } - ``` - -5. **Rate Limit Precedence:** - - Domain-specific limits (highest priority) - - Pattern-specific limits - - Global limits (lowest priority) - -### Integration Status -- ✅ Rate limiter supports per-domain limits -- ✅ UnifiedEmailServer applies domain limits on startup -- ✅ Domain limits properly override global/pattern limits -- ✅ SMTP server handlers now enforce rate limits (COMPLETED 2025-05-29) -- ⚠️ Hour/day limits need additional implementation in rate limiter - -### SMTP Handler Integration (2025-05-29) - COMPLETED -Rate limiting is now fully integrated into SMTP server handlers: - -1. **UnifiedEmailServer Enhancement:** - - Added `getRateLimiter()` method to provide access to the rate limiter - -2. **ConnectionManager Integration:** - - Replaced custom rate limiting with UnifiedRateLimiter - - Now uses `rateLimiter.recordConnection(ip)` for all connection checks - - Maintains local IP tracking for resource cleanup only - -3. **CommandHandler Integration:** - - `handleMailFrom()`: Checks message rate limits with domain context - - `handleRcptTo()`: Enforces recipient limits per message - - `handleAuth*()`: Records authentication failures and blocks after threshold - - Error handling: Records syntax/command errors and blocks after threshold - -4. **SMTP Response Codes:** - - `421`: Temporary rate limit (client should retry later) - - `451`: Temporary recipient rejection - - `421 Too many errors`: IP blocked due to excessive errors - - `421 Too many authentication failures`: IP blocked due to auth failures - -### Next Steps -The only remaining item is implementing hour/day rate limits in the UnifiedRateLimiter, which would require: -1. Additional counters for hourly and daily windows -2. Separate tracking for these longer time periods -3. Cleanup logic for expired hourly/daily counters - -## DNS Architecture Refactoring (2025-05-30) - COMPLETED - -### Overview -The DNS functionality has been refactored from UnifiedEmailServer to a dedicated DnsManager class for better discoverability and separation of concerns. - -### Key Changes -1. **Renamed DnsValidator to DnsManager:** - - Extended functionality to handle both validation and creation of DNS records - - Added `ensureDnsRecords()` as the main entry point - - Moved DNS record creation logic from UnifiedEmailServer - -2. **DnsManager Responsibilities:** - - Validate DNS configuration for all modes (forward, internal-dns, external-dns) - - Create DNS records for internal-dns domains - - Create DKIM records for all domains (when DKIMCreator is provided) - - Store DNS records in StorageManager for persistence - -3. **DNS Record Creation Flow:** - ```typescript - // In UnifiedEmailServer - const dnsManager = new DnsManager(this.dcRouter); - await dnsManager.ensureDnsRecords(domainConfigs, this.dkimCreator); - ``` - -4. **Testing Pattern for DNS:** - - Mock the DNS server in tests by providing a mock `registerHandler` function - - Store handlers in a Map with key format: `${domain}:${types.join(',')}` - - Retrieve handlers with key format: `${domain}:${type}` - - Example mock implementation: - ```typescript - this.dnsServer = { - registerHandler: (name: string, types: string[], handler: () => any) => { - const key = `${name}:${types.join(',')}`; - this.dnsHandlers.set(key, handler); - } - }; - ``` - -### Benefits -- DNS functionality is now easily discoverable in DnsManager -- Clear separation between DNS management and email server logic -- UnifiedEmailServer is simpler and more focused -- All DNS-related tests pass successfully ## SmartMetrics Integration (2025-06-12) - COMPLETED @@ -1366,9 +715,8 @@ Located in `ts/cache/documents/`: |-------|---------|-------------| | `CachedEmail` | Email queue items | 30 days | | `CachedIPReputation` | IP reputation lookups | 24 hours | -| `CachedBounce` | Bounce records | 30 days | -| `CachedSuppression` | Suppression list | 30 days / permanent | -| `CachedDKIMKey` | DKIM key pairs | 90 days | + +Note: CachedBounce, CachedSuppression, and CachedDKIMKey were removed in the smartmta migration (smartmta handles its own persistence for those). ### Usage Pattern ```typescript diff --git a/readme.md b/readme.md index 35ceeef..ded34c3 100644 --- a/readme.md +++ b/readme.md @@ -2,9 +2,9 @@ ![](https://code.foss.global/serve.zone/docs/raw/branch/main/dcrouter.png) -**dcrouter: A powerful traffic router designed to be the gateway for your datacenter.** 🚀 +**dcrouter: The all-in-one gateway for your datacenter.** 🚀 -A comprehensive traffic routing solution that provides unified gateway capabilities for HTTP/HTTPS, TCP/SNI, email (SMTP), DNS protocols, and RADIUS authentication.
