### Configuration Structure
|
||||
|
||||
The application uses `config.json` for configuration with the following structure:
|
||||
- `couchDb`: Database connection settings (URL, credentials, database name - note: the database field is now ignored as each mail source gets its own database)
|
||||
- `couchDb`: Database connection settings (URL, credentials)
|
||||
- `mailSources`: Array of mail sources with individual settings:
|
||||
- Protocol support (currently only IMAP)
|
||||
- Connection details (host, port, credentials)
|
||||
|
|

### Key Dependencies
|
||||
|
|
@ -108,33 +115,45 @@ This design ensures the same `config.json` format will work for both Go and Rust
|
|||
- `github.com/emersion/go-imap/v2`: IMAP client library
|
||||
- `github.com/go-kivik/kivik/v4`: CouchDB client library
|
||||
|
||||
### Incremental Sync Implementation
|
||||
|
||||
The application implements intelligent incremental synchronization to avoid re-processing messages:
|
||||
|
||||
- **Sync Metadata Storage**: Each mailbox sync operation stores metadata including last sync timestamp and highest UID processed
|
||||
- **IMAP SEARCH Integration**: Uses IMAP SEARCH with SINCE criteria for efficient server-side filtering of new messages
|
||||
- **Per-Mailbox Tracking**: Sync state is tracked independently for each mailbox in each account
|
||||
- **Fallback Behavior**: Gracefully falls back to fetching recent messages if IMAP SEARCH fails
|
||||
- **First Sync Handling**: Initial sync can use config `since` date or perform full sync
|
||||
|
||||
Sync metadata documents are stored in CouchDB with ID format: `sync_metadata_{mailbox}` and include:
|
||||
- `lastSyncTime`: When this mailbox was last successfully synced
|
||||
- `lastMessageUID`: Highest UID processed in the last sync
|
||||
- `messageCount`: Number of messages processed in the last sync
|
||||
|
||||
### Development Notes
|
||||
|
||||
- The main entry point is `main.go` which orchestrates the configuration loading, CouchDB setup, and mail source processing
|
||||
- Each mail source gets its own CouchDB database named using `GenerateAccountDBName()` function
|
||||
- Each mail source gets its own CouchDB database named using `GenerateAccountDBName()` function with `m2c_` prefix
|
||||
- Each mail source is processed sequentially with proper error handling
|
||||
- The application currently uses placeholder message data for testing the storage pipeline
|
||||
- Message filtering by folder (include/exclude) and date (since) is implemented
|
||||
- The application uses real IMAP message parsing with go-message library for full email processing
|
||||
- Message filtering by folder (wildcard patterns), date (since), and keywords is implemented
|
||||
- Duplicate detection prevents re-storing existing messages
|
||||
- Sync vs Archive mode determines whether to remove documents from CouchDB when they're no longer in the mail account
|
||||
- Email attachments are stored as native CouchDB attachments linked to the email document
|
||||
- No tests are currently implemented
|
||||
- Comprehensive test environment with Podman containers and automated test scripts
|
||||
- The application uses automatic config file discovery as documented above
|
||||
|
||||
### Next Steps
|
||||
|
||||
To complete the implementation, the following items need to be addressed:
|
||||
The following enhancements could further improve the implementation:
|
||||
|
||||
1. **Real IMAP Message Parsing**: Replace placeholder message generation with actual IMAP message fetching and parsing using the correct go-imap/v2 API
|
||||
2. **Message Body Extraction**: Implement proper text/plain and text/html body extraction from multipart messages
|
||||
3. **Keyword Filtering**: Add support for filtering messages by keywords in:
|
||||
- Subject line (`subjectKeywords`)
|
||||
- Sender addresses (`senderKeywords`)
|
||||
- Recipient addresses (`recipientKeywords`)
|
||||
4. **Attachment Handling**: Add support for email attachments (optional)
|
||||
5. **Error Recovery**: Add retry logic for network failures and partial sync recovery
|
||||
6. **Performance**: Add batch operations for better CouchDB insertion performance
|
||||
7. **Testing**: Add unit tests for all major components
|
||||
1. **Error Recovery**: Add retry logic for network failures and partial sync recovery
|

# mail2couch
|
||||
|
||||
A utility to back up mail from various sources to couchdb
|
||||
A powerful email backup utility that synchronizes mail from IMAP accounts to CouchDB databases with intelligent incremental sync, comprehensive filtering, and native attachment support.
|
||||
|
||||
At least two implementations will be available, on in Rust and one in Go.
|
||||
## Features
|
||||
|
||||
### Core Functionality
|
||||
- **IMAP Email Backup**: Connect to any IMAP server (Gmail, Outlook, self-hosted)
|
||||
- **CouchDB Storage**: Store emails as JSON documents with native CouchDB attachments
|
||||
- **Incremental Sync**: Efficiently sync only new messages using IMAP SEARCH with timestamp tracking
|
||||
- **Per-Account Databases**: Each mail source gets its own CouchDB database for better organization
|
||||
- **Duplicate Prevention**: Automatic detection and prevention of duplicate message storage
|
||||
|
||||
### Sync Modes
|
||||
- **Archive Mode**: Preserve all messages ever seen, even if deleted from mail server (default)
|
||||
- **Sync Mode**: Maintain 1-to-1 relationship with mail server (removes deleted messages from CouchDB)
|
||||
|
||||
### Advanced Filtering
|
||||
- **Wildcard Folder Patterns**: Use `*`, `?`, `[abc]` patterns for flexible folder selection
|
||||
- **Keyword Filtering**: Filter messages by keywords in subjects, senders, or recipients
|
||||
- **Date Filtering**: Process only messages since a specific date
|
||||
- **Include/Exclude Logic**: Combine multiple filter types for precise control
|
||||
|
||||
### Message Processing
|
||||
- **Full MIME Support**: Parse multipart messages, HTML/plain text, and embedded content
|
||||
- **Native Attachments**: Store email attachments as CouchDB native attachments with compression
|
||||
- **Complete Headers**: Preserve all email headers and metadata
|
||||
- **UTF-8 Support**: Handle international characters and special content
|
||||
|
||||
### Operational Features
|
||||
- **Automatic Config Discovery**: Finds configuration files in standard locations
|
||||
- **Command Line Control**: Override settings with `--max-messages` and `--config` flags
|
||||
- **Comprehensive Logging**: Detailed output for monitoring and troubleshooting
|
||||
- **Error Resilience**: Graceful handling of network issues and server problems
|
||||
|
||||
## Quick Start
|
||||
|
||||
### Installation
|
||||
|
||||
1. **Install dependencies**:
|
||||
```bash
|
||||
# Go 1.21+ required
|
||||
go version
|
||||
```
|
||||
|
||||
2. **Clone and build**:
|
||||
```bash
|
||||
git clone <repository-url>
|
||||
cd mail2couch/go
|
||||
go build -o mail2couch .
|
||||
```
|
||||
|
||||
### Basic Usage
|
||||
|
||||
1. **Create configuration file** (`config.json`):
|
||||
```json
|
||||
{
|
||||
"couchDb": {
|
||||
"url": "http://localhost:5984",
|
||||
"user": "admin",
|
||||
"password": "password"
|
||||
},
|
||||
"mailSources": [
|
||||
{
|
||||
"name": "Personal Gmail",
|
||||
"enabled": true,
|
||||
"protocol": "imap",
|
||||
"host": "imap.gmail.com",
|
||||
"port": 993,
|
||||
"user": "your-email@gmail.com",
|
||||
"password": "your-app-password",
|
||||
"mode": "archive",
|
||||
"folderFilter": {
|
||||
"include": ["*"],
|
||||
"exclude": ["[Gmail]/Trash", "[Gmail]/Spam"]
|
||||
}
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
2. **Run mail2couch**:
|
||||
```bash
|
||||
./mail2couch
|
||||
```
|
||||
|
||||
The application will:
|
||||
- Create a CouchDB database named `m2c_personal_gmail`
|
||||
- Sync all folders except Trash and Spam
|
||||
- Store messages with native attachments
|
||||
- Track sync state for efficient incremental updates
|
||||
|
||||
## Configuration
|
||||
|
||||
### Configuration File Discovery
|
||||
|
||||
mail2couch automatically searches for configuration files in this order:
|
||||
1. Path specified by `--config` flag
|
||||
2. `./config.json` (current directory)
|
||||
3. `./config/config.json` (config subdirectory)
|
||||
4. `~/.config/mail2couch/config.json` (user config directory)
|
||||
5. `~/.mail2couch.json` (user home directory)
|
||||
|
||||
### Command Line Options
|
||||
|
||||
```bash
|
||||
./mail2couch [options]
|
||||
|
||||
Options:
|
||||
--config PATH Specify configuration file path
|
||||
--max-messages N Limit messages processed per mailbox per run (0 = unlimited)
|
||||
```
|
||||
|
||||
### Folder Pattern Examples
|
||||
|
||||
| Pattern | Description | Matches |
|
||||
|---------|-------------|---------|
|
||||
| `"*"` | All folders | `INBOX`, `Sent`, `Work/Projects`, etc. |
|
||||
| `"INBOX"` | Exact match | `INBOX` only |
|
||||
| `"Work*"` | Prefix match | `Work`, `Work/Projects`, `WorkStuff` |
|
||||
| `"*/Archive"` | Suffix match | `Personal/Archive`, `Work/Archive` |
|
||||
| `"Work/*"` | Subfolder match | `Work/Projects`, `Work/Clients` |
|
||||
|
||||
### Keyword Filtering Examples
|
||||
|
||||
```json
|
||||
{
|
||||
"messageFilter": {
|
||||
"subjectKeywords": ["urgent", "meeting", "invoice"],
|
||||
"senderKeywords": ["@company.com", "noreply@"],
|
||||
"recipientKeywords": ["team@", "support@"]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Advanced Configuration Examples
|
||||
|
||||
See the [example configurations](#example-configurations) section below for detailed configuration scenarios.
|
||||
|
||||
## Testing
|
||||
|
||||
A comprehensive test environment is included with Podman containers:
|
||||
|
||||
```bash
|
||||
cd test
|
||||
|
||||
# Quick automated testing (recommended)
|
||||
./run-tests.sh # Complete integration test with automatic cleanup
|
||||
|
||||
# Specialized feature testing
|
||||
./test-wildcard-patterns.sh # Test folder pattern matching
|
||||
./test-incremental-sync.sh # Test incremental synchronization
|
||||
|
||||
# Manual testing environment
|
||||
./start-test-env.sh # Start persistent test environment
|
||||
# ... manual testing with various configurations ...
|
||||
./stop-test-env.sh # Clean up when done
|
||||
```
|
||||
|
||||
## Architecture
|
||||
|
||||
### Database Structure
|
||||
- **Per-Account Databases**: Each mail source creates its own CouchDB database with `m2c_` prefix
|
||||
- **Message Documents**: Each email becomes a CouchDB document with metadata
|
||||
- **Native Attachments**: Email attachments stored as CouchDB attachments (compressed)
|
||||
- **Sync Metadata**: Tracks incremental sync state per mailbox
|
||||
|
||||
### Document Structure
|
||||
```json
|
||||
{
|
||||
"_id": "INBOX_12345",
|
||||
"sourceUid": "12345",
|
||||
"mailbox": "INBOX",

"length": 54321
|
||||
}
|
||||
}
|

## Production Deployment
|
||||
|
||||
### Security Considerations
|
||||
- Use app passwords instead of account passwords
|
||||
- Store configuration files with restricted permissions (600)
|
||||
- Use HTTPS for CouchDB connections in production
|
||||
- Consider encrypting sensitive configuration data
|
||||
|
||||
### Monitoring and Maintenance
|
||||
- Review sync metadata documents for sync health
|
||||
- Monitor CouchDB database sizes and compaction
|
||||
- Set up log rotation for application output
|
||||
- Schedule regular backups of CouchDB databases
|
||||
|
||||
### Performance Tuning
|
||||
- Use `--max-messages` to limit processing load
|
||||
- Run during off-peak hours for large initial syncs
|
||||
- Monitor IMAP server rate limits and connection limits
|
||||
- Consider running multiple instances for different accounts
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
**Connection Errors**:
|
||||
- Verify IMAP server settings and credentials
|
||||
- Check firewall and network connectivity
|
||||
- Ensure correct ports (993 for TLS, 143 for plain)
|
||||
|
||||
**Authentication Failures**:
|
||||
- Use app passwords for Gmail, Outlook, and other providers
|
||||
- Enable "Less Secure Apps" if required by provider
|
||||
- Verify account permissions and 2FA settings
|
||||
|
||||
**Sync Issues**:
|
||||
- Check CouchDB connectivity and permissions
|
||||
- Review sync metadata documents for error states
|
||||
- Verify folder names and patterns match server structure
|
||||
|
||||
**Performance Problems**:
|
||||
- Use date filtering (`since`) for large mailboxes
|
||||
- Implement `--max-messages` limits for initial syncs
|
||||
- Monitor server-side rate limiting
|
||||
|
||||
For detailed troubleshooting, see the [test environment documentation](test/README.md).

### Run Full Integration Tests
|
||||
### Run Basic Integration Tests
|
||||
```bash
|
||||
./run-tests.sh
|
||||
```
|
||||
This will:
|
||||
1. Start all containers
|
||||
This comprehensive test will:
|
||||
1. Start all containers with cleanup
|
||||
2. Populate test data
|
||||
3. Run mail2couch
|
||||
4. Verify results
|
||||
5. Clean up
|
||||
3. Build and run mail2couch
|
||||
4. Verify database creation and document storage
|
||||
5. Test incremental sync behavior
|
||||
6. Clean up automatically
|
||||
|
||||
### Run Wildcard Pattern Tests

@ -32,20 +33,56 @@ This will test various wildcard folder patterns including:
|
|||
- `*/Drafts` (subfolder patterns)
|
||||
- Complex include/exclude combinations
|
||||
|
||||
### Manual Testing
|
||||
### Run Incremental Sync Tests
|
||||
```bash
|
||||
# Start test environment
|
||||
./test-incremental-sync.sh
|
||||
```
|
||||
This will test incremental synchronization functionality:
|
||||
- First sync establishes baseline
|
||||
- New messages are added to test accounts
|
||||
- Second sync should only fetch new messages
|
||||
- Sync metadata tracking and IMAP SEARCH with SINCE
|
||||
|
||||
### Manual Testing Environment
|
||||
```bash
|
||||
# Start persistent test environment (for manual experimentation)
|
||||
./start-test-env.sh
|
||||
|
||||
# Run mail2couch manually
|

|
||||
# Stop test environment when done
|
||||
cd ../test
|

./stop-test-env.sh
|
||||
```
|
||||
|
||||
## Test Scripts Overview
|
||||
|
||||
### Automated Testing (Recommended)
|
||||
- **`./run-tests.sh`**: Complete integration test with automatic cleanup
|
||||
- Starts containers, populates data, runs mail2couch, verifies results
|
||||
- Tests basic functionality, database creation, and incremental sync
|
||||
- Cleans up automatically - perfect for CI/CD or quick validation
|
||||
|
||||
### Specialized Feature Testing
|
||||
- **`./test-wildcard-patterns.sh`**: Comprehensive folder pattern testing
|
||||
- Tests `*`, `Work*`, `*/Drafts`, and complex include/exclude patterns
|
||||
- Self-contained with own setup/teardown
|
||||
- **`./test-incremental-sync.sh`**: Incremental synchronization testing
|
||||
- Tests sync metadata tracking and IMAP SEARCH with SINCE
|
||||
- Multi-step validation: baseline sync → add messages → incremental sync
|
||||
- Self-contained with own setup/teardown
|
||||
|
||||
### Manual Testing Environment
|
||||
- **`./start-test-env.sh`**: Start persistent test containers
|
||||
- Keeps environment running for manual experimentation
|
||||
- Populates test data once
|
||||
- Use with different configurations for development
|
||||
- **`./stop-test-env.sh`**: Clean up manual test environment
|
||||
- Only needed after using `start-test-env.sh`
