## SMTP Implementation Findings (2025-05-25)
|
||||
|
||||
### Fixed Issues
|
||||
|
||||
1. **AUTH Mechanism Implementation**
|
||||
- The server-side AUTH command handler was incomplete
|
||||
- Implemented `handleAuthPlain` with proper PLAIN authentication flow
|
||||
- Implemented `handleAuthLogin` with state-based LOGIN authentication flow
|
||||
- Added `validateUser` function to test server configuration
|
||||
- AUTH tests now expect STARTTLS instead of direct TLS (`secure: false` with `requireTLS: true`)
|
||||
|
||||
2. **TLS Connection Timeout Handling**
|
||||
- For secure connections, the client was waiting for 'connect' event instead of 'secureConnect'
|
||||
- Fixed in `ConnectionManager.establishSocket()` to use the appropriate event based on connection type
|
||||
- This prevents indefinite hangs during TLS handshake failures
|
||||
|
||||
3. **STARTTLS Server Implementation**
|
||||
- Removed incorrect `(tlsSocket as any)._start()` call which is client-side only
|
||||
- Server-side TLS sockets handle handshake automatically when data arrives
|
||||
- The `_start()` method caused Node.js assertion failure: `wrap->is_client()`
|
||||
|
||||
4. **Edge Case Test Patterns**
|
||||
- Tests using non-existent `smtpClient.connect()` method - use `verify()` instead
|
||||
- SMTP servers must handle DATA mode properly by processing lines individually
|
||||
- Empty/minimal server responses need to be valid SMTP codes (e.g., "250 OK\r\n")
|
||||
- Out-of-order pipelined responses break SMTP protocol - responses must be in order
|
||||
|
||||
### Common Test Patterns
|
||||
|
||||
1. **Connection Testing**
|
||||
```typescript
|
||||
const verified = await smtpClient.verify();
|
||||
expect(verified).toBeTrue();
|
||||
```
|
||||
|
||||
2. **Server Data Handling**
|
||||
```typescript
|
||||
socket.on('data', (data) => {
|
||||
const lines = data.toString().split('\r\n');
|
||||
lines.forEach(line => {
|
||||
if (!line && lines[lines.length - 1] === '') return;
|
||||
// Process each line individually
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
3. **Authentication Setup**
|
||||
```typescript
|
||||
auth: {
|
||||
required: true,
|
||||
methods: ['PLAIN', 'LOGIN'],
|
||||
validateUser: async (username, password) => {
|
||||
return username === 'testuser' && password === 'testpass';
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Progress Tracking
|
||||
- Fixed 8 tests total (as of 2025-05-25)
|
||||
- 30 error logs remaining in `.nogit/testlogs/00err/`
|
||||
- Edge cases, email composition, error handling, performance, reliability, RFC compliance, and security tests still need fixes
