# DcRouter Storage Manager and Email DNS Configuration Plan
## Overview
Implement a central storage manager for DcRouter that supports multiple storage backends (filesystem, custom functions, or memory) and enhance email configuration with unified domain management that cleanly separates infrastructure setup from routing rules.
### Key Concept: Infrastructure vs Routing
- **Email Config (domains)** = Infrastructure setup (which domains, DNS handling, DKIM, rate limits)
- **Route Config (routes)** = ALL email handling logic (forward, process, deliver, reject)
- **Default behavior**: If no route matches, log the email and show warning
## Core Requirements
### Storage Manager
- Flexible storage backend support
- Filesystem storage via `fsPath`
- Custom storage via read/write functions
- Memory storage as fallback with console warning
- Key-value storage interface
- Used by all components that need persistence
### Email DNS Configuration
- **Infrastructure vs Routing Separation**:
- **Email Config (domains)** = Infrastructure setup (which domains, DNS handling, defaults)
- **Route Config (routes)** = Individual email routing (pattern matching, specific actions)
- **DKIM Always Enabled** - All domains get DKIM keys automatically
- **Per-Domain DNS Modes** - Each email domain can have different DNS handling
- **Forward Mode** - Simple forwarding to another server (no local processing)
- **Internal DNS Mode** - Use the built-in DNS server with NS delegation
- **External DNS Mode** - Use external DNS with validation and setup instructions
- Storage required for DNS records, DKIM keys, and email routing data
## Architecture
### Storage Manager Design
```typescript
interface IStorageConfig {
fsPath?: string;
readFunction?: (key: string) => Promise<string>;
writeFunction?: (key: string, value: string) => Promise<void>;
}
class StorageManager {
// Unified interface for all storage operations
async get(key: string): Promise<string | null>
async set(key: string, value: string): Promise<void>
async delete(key: string): Promise<void>
async list(prefix?: string): Promise<string[]>
async exists(key: string): Promise<boolean>
}
```
### DcRouter Configuration
```typescript
interface IDcRouterOptions {
// ... existing options
storage?: {
fsPath?: string;
readFunction?: (key: string) => Promise<string>;
writeFunction?: (key: string, value: string) => Promise<void>;
};
emailConfig?: IUnifiedEmailServerOptions;
}
// Updated UnifiedEmailServerOptions
interface IUnifiedEmailServerOptions {
ports: number[];
hostname: string;
domains: IEmailDomainConfig[];
// Pattern-based routing rules (evaluated after domain matching)
routes: IEmailRoute[];
// Global defaults for all domains
defaults?: {
dnsMode?: 'forward' | 'internal-dns' | 'external-dns';
dkim?: IEmailDomainConfig['dkim'];
rateLimits?: IEmailDomainConfig['rateLimits'];
};
// ... existing options (auth, tls, limits, etc.)
}
interface IEmailDomainConfig {
// Domain name
domain: string;
// DNS handling mode
dnsMode: 'forward' | 'internal-dns' | 'external-dns';
// DNS configuration based on mode
dns?: {
// For 'forward' mode
forward?: {
skipDnsValidation?: boolean;
targetDomain?: string;
};
// For 'internal-dns' mode (requires dnsDomain in DcRouter)
internal?: {
/** TTL for DNS records in seconds (default: 3600) */
ttl?: number;
/** MX record priority (default: 10) */
mxPriority?: number;
};
// For 'external-dns' mode
external?: {
/**
* Custom DNS servers to query (rarely needed)
* Default: Follow standard DNS resolution chain
* Only use for special cases like internal corporate DNS
*/
servers?: string[];
/**
* Which DNS records to validate
* Default: ['MX', 'SPF', 'DKIM', 'DMARC']
* Validation always runs; setup instructions always shown if missing
*/
requiredRecords?: ('MX' | 'SPF' | 'DKIM' | 'DMARC')[];
};
};
// Per-domain DKIM settings
// DKIM is always enabled; use this to override defaults
dkim?: {
/** DKIM selector (default: 'default') */
selector?: string;
/** Key size in bits (default: 2048) */
keySize?: number;
/** Automatically rotate keys (default: false) */
rotateKeys?: boolean;
/** Days between key rotations (default: 90) */
rotationInterval?: number;
};
// Per-domain rate limits
rateLimits?: {
outbound?: {
messagesPerMinute?: number;
messagesPerHour?: number;
messagesPerDay?: number;
};
inbound?: {
messagesPerMinute?: number;
connectionsPerIp?: number;
recipientsPerMessage?: number;
};
};
}
```
## Validation and Warnings
### No Route Match Warning
When an email arrives and no route matches:
```typescript
console.warn(
'⚠️ WARNING: No route matched for email:\n' +
` From: ${email.from}\n` +
` To: ${email.to}\n` +
` Subject: ${email.subject}\n` +
' Email will be logged but not processed.\n' +
' Add a route to handle this email pattern.'
);
// Email is stored in logs but no further action taken
```
### Internal DNS Mode Validation
When a domain is configured with `dnsMode: 'internal-dns'`:
```typescript
// Check if dnsDomain is configured
if (!dcRouter.dnsDomain) {
console.error(
'❌ ERROR: Domain "mail.hosted.com" is configured to use internal DNS,\n' +
' but dnsDomain is not set in DcRouter configuration.\n' +
' Please configure dnsDomain to enable the DNS server.\n' +
' Example: dnsDomain: "ns.myservice.com"'
);
throw new Error('Internal DNS mode requires dnsDomain to be configured');
}
// Check if NS delegation exists
const nsRecords = await dns.resolveNs(domainConfig.domain);
const isDelegated = nsRecords.includes(dcRouter.dnsDomain);
if (!isDelegated) {
console.log(
'📋 DNS Delegation Required for ' + domainConfig.domain + ':\n' +
'━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━\n' +
'Please add this NS record at your domain registrar:\n' +
` ${domainConfig.domain}. NS ${dcRouter.dnsDomain}.\n` +
'━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━\n' +
'This delegation is required for internal DNS mode to work.'
);
} else {
console.log(
'✅ NS delegation verified: ' + domainConfig.domain + ' -> ' + dcRouter.dnsDomain
);
}
```
### External DNS Mode Validation
When a domain is configured with `dnsMode: 'external-dns'`:
```typescript
// Check current DNS records
const currentRecords = await checkDnsRecords('mail.external.com');
const requiredChanges = [];
if (!currentRecords.mx) {
requiredChanges.push('Add MX record: external.com -> mail.external.com (priority 10)');
}
if (!currentRecords.spf) {
requiredChanges.push('Add TXT record: external.com -> "v=spf1 a mx ~all"');
}
// DKIM is always enabled, so always check for DKIM record
if (!currentRecords.dkim) {
const dkimPublicKey = await storage.get(`/email/dkim/${domain}/public.key`);
requiredChanges.push(
`Add TXT record: ${domainConfig.dkim?.selector || 'default'}._domainkey.external.com -> "${dkimPublicKey}"`
);
}
if (requiredChanges.length > 0) {
console.log(
'📋 DNS Configuration Required for mail.external.com:\n' +
'━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━\n' +
requiredChanges.map((change, i) => `${i + 1}. ${change}`).join('\n') +
'\n━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━'
);
}
```
### Forward Mode Validation
When a domain is configured with `dnsMode: 'forward'`:
- No DNS validation needed (pure forwarding)
- DKIM keys are still generated and stored (for consistency)
- DKIM signing only happens if routes process the email (not pure forward)
- Note: Actual forwarding behavior must be defined in routes

/email/dkim/{domain}/public.key
/email/routes/{routeId}.json
/email/reputation/{domain}.json
/dns/records/{domain}/{type}/{id}.json
/dns/zones/{domain}.json
/certificates/{domain}/cert.pem
/certificates/{domain}/key.pem
```
### Memory Storage Warning
```typescript
console.warn(
'⚠️ WARNING: StorageManager is using in-memory storage.\n' +
' Data will be lost when the process restarts.\n' +
' Configure storage.fsPath or storage functions for persistence.'
);
```
### Configuration Examples
#### Complete Email Domain Configuration
```typescript
{
dnsDomain: 'ns.myservice.com', // Required for internal-dns mode
emailConfig: {
ports: [25, 587, 465],
hostname: 'mail.myservice.com',
domains: [
{
// Forward-only domain (no local DNS needed)
domain: 'forwarded.com',
dnsMode: 'forward',
dns: {
forward: {
skipDnsValidation: false
}
}
// DKIM uses defaults (always enabled)
// Handling is defined in routes, not here!
},
{
// Using internal DNS server
domain: 'mail.hosted.com',
dnsMode: 'internal-dns',
dns: {
internal: {
mxPriority: 10 // Records are always auto-created for internal DNS
}
},
dkim: {
// Override DKIM defaults
keySize: 2048 // Using 2048 explicitly (same as default)
}
// Handling is defined in routes, not here!
},
{
// Using external DNS
domain: 'mail.external.com',
dnsMode: 'external-dns',
dns: {
external: {
// Validation runs automatically
// Only override requiredRecords if you want fewer checks
requiredRecords: ['MX', 'SPF', 'DKIM'] // Skipping DMARC check
}
},
// No dkim object needed - uses all defaults
rateLimits: {
outbound: {
messagesPerMinute: 100
}
}
}
],
// Pattern-based routing (ALL email handling happens here)
routes: [
// Forward all mail for forwarded.com
{
name: 'forward-domain',
match: { recipients: '*@forwarded.com' },
action: {
type: 'forward',
forward: {
host: '192.168.1.10',
port: 25,
preserveHeaders: true
}
}
},
// Process mail for hosted domains
{
name: 'process-hosted',
match: { recipients: ['*@mail.hosted.com', '*@mail.external.com'] },
action: {
type: 'process',
process: {
scan: true,
dkim: true,
spf: true,
queue: 'normal'
}
}
},
// VIP bypass scanning
{
name: 'vip-bypass',
match: { recipients: 'ceo@*' },
action: {
type: 'process',
process: { scan: false, queue: 'priority' }
}
},
// Reject large messages
{
name: 'large-reject',
match: {
recipients: '*@*',
sizeRange: { min: 50 * 1024 * 1024 }
},
action: {
type: 'reject',
reject: {
code: 552,
message: 'Message too large'
}
}
}
]
}
```
## Benefits
### Storage Manager Benefits
- **Flexibility**: Multiple storage backend options
- **Portability**: Easy to switch storage backends
- **Testing**: Memory backend for tests
- **Cloud-Ready**: Custom functions can use cloud storage
### Email DNS Benefits
- **Unified Configuration**: Infrastructure and routing cleanly separated
- **Flexible DNS Modes**: Choose per-domain how DNS is handled
- **External Mode**: Works with existing DNS infrastructure
- **Internal Mode**: Self-contained email system with automatic record creation
- **Forward Mode**: Simple mail forwarding without DNS complexity
- **Automatic Setup**: DNS records created automatically for internal mode
- **DKIM Management**: Keys generated and rotated automatically per domain
- **Per-Domain Settings**: Rate limits, DKIM, and handling customizable per domain
## Migration Path
1. Start with memory storage (with warning)
2. Configure filesystem path for persistence
3. Migrate to custom functions for cloud deployment
4. Switch DNS modes based on infrastructure
## Notes
- Storage manager is singleton within DcRouter instance
- All storage operations are async
- Keys are hierarchical (path-like)
- Values are strings (JSON for complex data)
- Internal DNS mode requires `dnsDomain` to be set in DcRouter
- Clean separation: domains = infrastructure, routes = handling
- Domain config only defines: which domains, DNS mode, DKIM settings, rate limits
- DKIM is always enabled for all domains (use dkim object to override defaults)
- ALL email handling logic lives in routes
- If no route matches, email is logged with warning
- This eliminates duplication between domain and route configs
### Default Values
- **DKIM** (always enabled for all domains):
- `selector`: 'default'
- `keySize`: 2048 bits
- `rotateKeys`: false
- `rotationInterval`: 90 days
- **Internal DNS Mode**:
- Records are always automatically created (MX, SPF, DKIM, DMARC)
- `ttl`: 3600 seconds (1 hour)
- `mxPriority`: 10
- **External DNS Mode**:
- `servers`: Standard DNS resolution chain (rarely needs override)
- `requiredRecords`: ['MX', 'SPF', 'DKIM', 'DMARC']
- Validation always runs on startup
- Setup instructions always shown if validation fails
### DNS Delegation for Internal Mode
When using internal DNS mode, you must manually configure NS delegation at your domain registrar:
**Example Setup:**
- DcRouter config: `dnsDomain: 'ns.myservice.com'`
- Email domain: `mail.example.com`
- **Manual step at registrar**: Add NS record: `mail.example.com. NS ns.myservice.com.`
This delegation tells the internet that your DcRouter DNS server (`ns.myservice.com`) is authoritative for `mail.example.com`. Without this manual step, internal DNS mode won't work.
**The system automatically checks NS delegation:**
- ✅ If properly delegated: `✅ NS delegation verified: mail.example.com -> ns.myservice.com`
- ❌ If not delegated: Shows instructions to add the NS record at your registrar
This validation ensures your internal DNS is properly configured before attempting to handle email.
