November 2024 performance summary: Delivered key features and stability improvements across Sundsvallskommun/api-service-email-reader and Sundsvallskommun/api-service-messaging, driving reliability in email attachment processing, EWS interactions, and configuration hygiene. Core features include automatic MIME type detection for email attachments using Apache Tika via a new ServiceUtil, with EWSMapper updated to leverage the utility for accurate MIME type inference (UF-10708). EWS integration was hardened to auto-create missing folders, refactor error handling, and improve recipient validation, ensuring a unique folder is selected before operations (UF-10974). Test resources were cleaned by removing the macOS-specific .DS_Store to reduce repository noise (commit 87d91d2304d0d1aaa8d7dafd31e4b4ee632e5b83). In the messaging service, obsolete configuration was cleaned by removing the 'port' property to reduce configuration clutter (UF-11112). These changes collectively reduce runtime errors, improve data accuracy for attachments, and simplify configuration management, delivering business value through more reliable email processing, easier maintenance, and clearer configuration boundaries. Technologies demonstrated include Java, Apache Tika integration, EWS, robust error handling, test hygiene, and configuration governance.
