# 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)

### Mail Transfer Agent (MTA)

The platform includes a robust Mail Transfer Agent (MTA) for enterprise-grade email handling with complete control over the email delivery process.
Additionally, the platform now features a consolidated email configuration system with pattern-based routing and a streamlined directory structure:

end
subgraph "External Services"

end
```
The MTA service provides:
- Complete SMTP server for receiving emails
- DKIM signing and verification
- SPF and DMARC support
- DNS record management
- Retry logic with queue processing
- TLS encryption
#### Key Features
Here's how to use the MTA service:
The email handling system provides:
- **Modular Directory Structure**: Clean organization with clear separation of concerns:
- **mail/core**: Core email models and basic functionality (Email, BounceManager, etc.)
- **mail/delivery**: Email delivery mechanisms (MTA, SMTP server, rate limiting)
- **mail/routing**: DNS and domain routing capabilities
- **mail/security**: Authentication and security features (DKIM, SPF, DMARC)
- **mail/services**: High-level services and API interfaces
- **Pattern-based Routing**: Route emails based on glob patterns like `*@domain.com` or `*@*.domain.com`
- **Multi-Modal Processing**: Handle different email domains with different processing modes:
- **Forward Mode**: SMTP forwarding to other servers
- **MTA Mode**: Full Mail Transfer Agent capabilities
- **Process Mode**: Store-and-forward with content scanning
- **Unified Configuration**: Single configuration interface for all email handling
- **Shared Infrastructure**: Use same ports (25, 587, 465) for all email handling
- **Complete SMTP Server**: Receive emails with TLS and authentication support
- **DKIM, SPF, DMARC**: Full email authentication standard support
- **Content Scanning**: Check for spam, viruses, and other threats
- **Advanced Delivery Management**: Queue, retry, and track delivery status
#### Using the Consolidated Email System
Here's how to use the consolidated email system:
```ts
import { MtaService, Email } from '@serve.zone/platformservice';
import { DcRouter, IEmailConfig, EmailProcessingMode } from '@serve.zone/platformservice';
async function setupEmailHandling() {
// Configure the email handling system
const dcRouter = new DcRouter({
emailConfig: {
ports: [25, 587, 465],
hostname: 'mail.example.com',
// TLS configuration
tls: {
certPath: '/path/to/cert.pem',
keyPath: '/path/to/key.pem'
},
// Default handling for unmatched domains
defaultMode: 'forward' as EmailProcessingMode,
defaultServer: 'fallback.mail.example.com',
defaultPort: 25,
// Pattern-based routing rules
domainRules: [
{
// Forward all company.com emails to internal mail server
pattern: '*@company.com',
mode: 'forward' as EmailProcessingMode,
target: {
server: 'internal-mail.company.local',
port: 25,
useTls: true
}
},
{
// Process notifications.company.com with MTA
pattern: '*@notifications.company.com',
mode: 'mta' as EmailProcessingMode,
mtaOptions: {
domain: 'notifications.company.com',
dkimSign: true,
dkimOptions: {
domainName: 'notifications.company.com',
keySelector: 'mail',
privateKey: '...'
}
}
},
{
// Scan marketing emails for content and transform
pattern: '*@marketing.company.com',
mode: 'process' as EmailProcessingMode,
contentScanning: true,
scanners: [
{
type: 'spam',
threshold: 5.0,
action: 'tag'
}
],
transformations: [
{
type: 'addHeader',
header: 'X-Marketing',
value: 'true'
}
]
}
]
}
});
// Start the system
await dcRouter.start();
console.log('DcRouter with email handling started');
// Later, you can update rules dynamically
await dcRouter.updateDomainRules([
{
pattern: '*@newdomain.com',
mode: 'forward' as EmailProcessingMode,
target: {
server: 'mail.newdomain.com',
port: 25
}
}
]);
}
setupEmailHandling();
```
#### Using the MTA Service Directly
You can still use the MTA service directly for more granular control with our new modular directory structure:
```ts
import { SzPlatformService } from '@serve.zone/platformservice';
import { MtaService } from '@serve.zone/platformservice/mail/delivery';
import { Email } from '@serve.zone/platformservice/mail/core';
import { ApiManager } from '@serve.zone/platformservice/mail/services';
async function useMtaService() {
// Initialize platform service
const platformService = new SzPlatformService();
await platformService.start();
// Initialize MTA service
const mtaService = new MtaService(platformService);
await mtaService.start();

### Conclusion
The `@serve.zone/platformservice` offers a robust set of features for modern application requirements, including but not limited to communication and AI services. By following the examples above, developers can integrate these services into their applications, harnessing the power of email, SMS, letters, MTA capabilities, and artificial intelligence seamlessly.
