- Add socket-handler mode eliminating internal port binding for improved performance
- Add `dnsDomain` config option for automatic DNS-over-HTTPS (DoH) setup
- Add `useSocketHandler` flag to email config for direct socket processing
- Update SmartProxy route generation to support socket-handler actions
- Integrate smartdns with manual HTTPS mode for DoH without port binding
- Add automatic route creation for DNS paths when dnsDomain is configured
- Update documentation with socket-handler configuration and benefits
- Improve resource efficiency by eliminating internal port forwarding
Replace legacy domain-rule based routing with flexible route-based system that supports:
- Multi-criteria matching (recipients, senders, IPs, authentication)
- Four action types (forward, process, deliver, reject)
- Moved DKIM signing to delivery phase for signature validity
- Connection pooling for efficient email forwarding
- Pattern caching for improved performance
This provides more granular control over email routing with priority-based matching and comprehensive test coverage.
