Worked on stabilizing mail-fetch workflows in the OCA/server-tools repository by addressing error handling inconsistencies in backend Python code. Focused on aligning the FetchmailServer.fetch_mail method signature with its superclass, the update introduced a raise_exception argument to ensure consistent error propagation throughout the inheritance chain. This change improved the reliability of mail processing pipelines by standardizing error handling and reducing the risk of unhandled exceptions. The solution maintained API compatibility for external callers, simplifying future maintenance and refactoring efforts. Demonstrated backend development skills in Python, with an emphasis on maintainability and robust error management within mail-processing components.
