HTTPError in message moderation for non-members

Hi, I was trying to send a msg by no member id but I am getting http error.

>>> client.domains
[<Domain "example.net">, <Domain "example.org">, <Domain "domain.org">]
>>> example = client.get_domain("domain.org")
>>> example
<Domain "domain.org">
>>> test_one = example.create_list('test-one')
>>> test_one
<List "<email address hidden>">
>>> msg
'From: <email address hidden>\nTo: <email address hidden>\nSubject: Something\nMessage-ID: <moderated_01>\n\nSome Text.\n\n'
>>> msg = """From: <email address hidden>
... To: <email address hidden>
... Subject: Something
... Message-ID: <moderated_01>
...
... Some text.
...
... """
>>> inq = client.queues['in']
>>> inq.inject('test-one.example.com', msg)
