If the mms proxy fails to retrieve a message since the message doesn't
exist at all. What content-type should be set in the m-retrieve.conf
pdu? The x-mms-retrieve-status can be set to 224. How about the
x-mms-retrieve-status-text and the pdu body part? Can I set the content
type to text/plain, and the desc in the body and status text field?

Thanks,
Jibin
