Hi @tyndyll
Thanks for this code.
I'm looking for some code like this to extract attachments but I'm getting a error when I run it.
Traceback (most recent call last): File "extract.py", line 28, in <module> mdir = mailbox.Maildir(mail_directory, factory=email.message_from_file) NameError: name 'mailbox' is not defined
Do you have missed some line when uploaded the code to github?

@crossmax you need to import relevant classes. Try opening it in pycharm. 👍
