TypeError whent trying to process_emailed_question()

edit

When I try to fetch emailed questions I'm seing this message:

#python manage.py post_emailed_questions
TypeError: process_emailed_question() takes at least 4 arguments (3 given)

My settings:

settings.py:

IMAP_HOST = 'imap-mail.outlook.com'
IMAP_HOST_USER = 'example@outlook.com'
IMAP_HOST_PASSWORD = '1234'
IMAP_PORT = '993'
IMAP_USE_TLS = True

in "settings/EMAIL/" : "Reply by email hostname": outlook.com or imap-mail.outlook.com (neither works)

and "Enable posting answers and comments by email" checked
