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: {
|
||||
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: [
|
||||
{
|

||||

|
||||

|
||||

|

}
|
||||
]
|
||||
}
|
||||
});
|
||||
|
||||
// Start the system
|
||||
await dcRouter.start();
|
||||
console.log('DcRouter with email handling started');
|
||||

||||
]);

||||
#### 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() {
