mbox_process

mbox_process is a python script to process an mbox email file to save each message as a file in a directory, along with any associated images and attachments.

Description

mbox email files are single text files used to contain collections of email. Email exports, including Google Takeout and Google Vault, use the mbox format as a choice (along with PST). This utility will take an mbox file as input and save all of the messages in a directory. Each message will be saved within it's own directory along with any images or attachments included in the original message.

The exported messages will include the sender, recipient, date received, subject, and email body in .txt (for plain/text messages) or .html (for plain/html messages) format. In addition to the message, any png or jpg images and attachments included in the email will be saved in the directory with the original message. Additional email metadata can be included by modifying the script.

Dependencies

Tested and run in Python 3.9 an Python 3.10
Requires mailbox, argparse, os, and csv libraries, which are included in the standard Python library

Executing program

Clone repository to directory or copy script to file named mbox_process.py
Usage:
