3.1.5.3 Receiving a POP3_AUTH_NTLM_Blob_Response Message

The expected state is inside_authentication.

On receiving this message, a client must de-encapsulate it to obtain the embedded NTLM message, and pass it to the NTLM subsystem for processing. The NTLM subsystem can then either report an error, or report success and return an NTLM message to be sent to the server.
