- Implement smart duplicate email detection using Message-ID and fallback signatures
- Add automatic folder creation with existing folder detection and reuse
- Enhance terminal output with colors, progress bars, and professional formatting
- Replace import folder functionality with original folder structure preservation
- Add comprehensive statistics tracking (duplicates, folder creation, etc.)
- Improve error handling with graceful date format fallbacks
- Add universal terminal compatibility with line-based formatting
- Update documentation and configuration files
- Provide clear user feedback for all migration decisions
Migration now intelligently skips duplicates, preserves folder structure,
and provides detailed feedback on what was migrated vs. what was skipped.
Key improvements:
- Either email OR username can be empty (but not both)
- Enhanced validation logic for authentication methods
- Improved error messages showing available auth methods
- More flexible IMAPConnection constructor with better defaults
Authentication options:
1. Email-only: SOURCE_EMAIL=user@domain.de, SOURCE_USERNAME=
2. Username-only: SOURCE_EMAIL=, SOURCE_USERNAME=username123
3. Both (fallback): Provide both for automatic fallback
4. Dual method: Username tried first, email as fallback
Configuration updates:
- Update .env.template with all four authentication examples
- Clarify requirements and optional nature of fields
- Add comprehensive authentication scenarios
Documentation updates:
- Expand README with four authentication options
- Add troubleshooting for different auth combinations
