I did the same search before trying this of course, and in about twenty
thousand saved messages I found precisely three multipart/mixeds.
None of those three was particularly important, and if the sender
really wanted to get through they could have simply re-sent the
message as plain text, like the bounce message says.

I really do think multipart/mixed ought to be deprecated net-wide.
