This commit completes the Rust implementation of mail2couch with full feature
parity to the Go version, including:
- Complete IMAP client with TLS support and retry logic
- Advanced email parsing with MIME multipart support using mail-parser
- Email attachment extraction and CouchDB storage
- Sync mode implementation with deleted message handling
- Enhanced error handling and retry mechanisms
- Identical command-line interface with bash completion
- Test configurations for both implementations
The Rust implementation now provides:
- Memory safety and type safety guarantees
- Modern async/await patterns with tokio/async-std
- Comprehensive error handling with anyhow/thiserror
- Structured logging and progress reporting
- Performance optimizations and retry logic
Test configurations created:
- rust/config-test-rust.json - Rust implementation test config
- go/config-test-go.json - Go implementation test config
- test-config-comparison.md - Detailed comparison documentation
- test-both-implementations.sh - Automated testing script
Both implementations can now be tested side-by-side with identical
configurations to validate feature parity and performance.

Adds a detailed analysis of the mail2couch project, covering its
purpose, architecture, and implementation details. The document
provides a summary of the project's functionality based on a review
of the README, schema files, and the Go source code.
The analysis includes:
- A high-level summary of what the project does.
- A detailed explanation of how it works, based on code review.
- Identification of potential problems, such as plaintext password
storage and the incomplete Rust implementation.
- A list of missing features, including the planned webmail UI
and OAuth2 support.
- Concrete suggestions for improvements, such as adding a --dry-run
mode, improving security, and clarifying the status of the Rust code.
- Add pflag dependency for POSIX/GNU-style command line parsing
- Replace Go standard flag package with pflag for better UX
- Implement long options with double dashes (--config, --max-messages, --help)
- Add short option aliases with single dashes (-c, -m, -h)
- Update help message with proper formatting and application description
- Update all documentation to reflect new flag syntax
- Update test scripts to use new command line format
GNU-style options provide better usability:
- Long descriptive options with --flag-name format
- Short single-character aliases for common options
- Standard help flag behavior with --help/-h
- Compatible with shell completion and standard conventions
Command line interface now supports:
- --config/-c FILE: Path to configuration file
- --max-messages/-m N: Message processing limit per mailbox
- --help/-h: Show help message and exit
All existing functionality preserved with improved command line experience.

- Add complete CouchDB document schema specifications in couchdb-schemas.md
- Create example JSON documents for mail and sync metadata structures
- Implement Rust schema definitions with full serde support and type safety
- Add validation script to ensure schema consistency across implementations
- Document field definitions, data types, and validation rules
- Provide Rust Cargo.toml with appropriate dependencies for future implementation
This establishes a solid foundation for the planned Rust implementation while ensuring
100% compatibility with existing Go implementation databases. Both implementations will
use identical document structures, field names, and database naming conventions.
Schema Features:
- Mail documents with native CouchDB attachment support
- Sync metadata for incremental synchronization
- Predictable document ID patterns for efficient access
- Cross-language type mappings and validation rules
- Example documents for testing and reference

- Remove obsolete CouchDB design documents (webmail.json, dashboard.json)
- Clean up webmail-related code from couch/couch.go (WebmailViews, CreateWebmailViews, etc.)
- Update documentation to focus on core mail-to-CouchDB storage functionality
- Add Future Plans section describing planned webmail viewer as separate component
- Apply go fmt formatting and ensure code quality standards
- Update test documentation to show raw CouchDB API access patterns
- Remove compiled binary from repository
This refactor simplifies the codebase to focus on its core purpose: efficiently
backing up emails from IMAP to CouchDB. The webmail interface will be developed
as a separate, optional component to maintain clean separation of concerns.
