## Description When using `ImapHook.download_mail_attachments`, attachments with identical filenames are silently overwritten, causing data loss. This PR adds an `overwrite_file` parameter to control how filename collisions are handled. ### Changes 1. **New `overwrite_file` parameter** on `download_mail_attachments` (default: `True` to preserve existing behavior) 2. When `overwrite_file=False`, duplicate filenames are saved with unique suffixes (`_1`, `_2`, etc.) before the file extension 3. New helper method `_make_unique_filename` for clean suffix generation 4. Unit tests for all scenarios: default behavior, explicit `True`, `False`, multiple duplicates, and files without extensions ### Related Closes #65870 -- This is an automated message from the Apache Git Service.
