Extracting the Body of Multipart Emails and Saving Attachments Using Python IMAP

When working on email processing, particularly with forwarded messages, it can often become a challenge to extract the body text and save attachments effectively. In this post, we will walk through a Python solution using the IMAP library that enables you to extract the body from multipart emails and save the attachments regardless of whether the email is new or forwarded.

The Challenge

Our goal is to build a Python script that effectively retrieves the body and attachments from incoming emails that meet specific criteria:

Emails are forwarded by users.

The body consists of text in the original email with no added text above the forwarded line.

Attachments may come from any part of the email.

You may already have some code that works for newly received emails, but it might struggle with forwarded emails. This guide provides an enhanced solution to handle those cases.

Overview of the Solution

We'll use the imaplib and email libraries in Python to connect to the mail server and retrieve emails. Here is what we'll do:

Connect to the IMAP server and log in.

Search for emails with a specific subject from a particular sender.

Parse the email content, extracting both the body and attachments.

Step-by-Step Implementation
