Netscape Mail encodes such emails as
  multipart/mixed
    multipart/alternative
      text/plain
      text/html
    attachments ...

In other words, it nests a multipart/alternative into a multipart/mixed.
I was in the process of developing a filter extend stripmime to handle
these other cases. In my flow, if I see a multipart/alternative entity,
I grab the text/plain sub-entity (I'm assuming it will always be there)
and ignore the rest.
