   ### Under which category would you file this issue?
   
   Providers
   
   ### Apache Airflow version
   
   3.2.1
   
   ### What happened and how to reproduce it?
   
   **Problem**
   
   When using `imap_hook.download_mail_attachments`, attachments with identical 
filenames are saved to disk using the same name, which leads to silent 
overwriting of previously downloaded files.
   
   This results in data loss without any warning, and there is currently no 
option to control this behavior.
   
   **How to reproduce**
   
   1. Receive multiple emails with attachments sharing the same filename (e.g. 
report.xlsx)
   2. Call imap_hook.download_mail_attachments
   3. Inspect the output directory
   4. Observe that only one file is present, as earlier files were overwritten
   
   ### What you think should happen instead?
   
   There should be a configurable way to control how filename collisions are 
handled when saving attachments, for example:
   
   - either allow overwriting existing files
   - or preserve all files by automatically renaming them.
   
   The current behavior should not be hardcoded without user control.
   
   **Possible improvement**
   
   Introduce a configurable parameter (e.g. overwrite_file or similar) that 
controls collision handling behavior:
   
   - overwrite_file=True → overwrite existing files (current behavior)
   - overwrite_file=False → preserve all files
   
   This would make the behavior explicit and safe for different use cases.
