[Useful] Python Script to List Duplicate Emails From Mailbox & Move Into Backup Folder

Team,

Attached is the script written to find          duplicate emails in a mailbox and move them to a backup          folder.

This will be helpful in scenarios after migrating or fixing email client-level issues.

The script will maintain its folder hierarchy under the destination folder while moving, making it easy to cross-verify and restore if needed.

Note: Reconstruction of the email box is not included in this script and can be performed later.
        

Usage :

[root@siddhesh ~]# python3.6 compare_move.py
Usage: python compare_move.py <folder_path> <dest_folder>
