One line of content:

> oops, forgot one!

Five lines of wrapper around that content:

> ------ =_NextPart_000_01BC7C3A.E163E920
> Content-Type: text/plain; charset="us-ascii"
> Content-Transfer-Encoding: 7bit
>
> oops, forgot one!

Fourteen lines of quoted reply message:

And a big attachment, forty+ lines, which I will largely elide:

More and more, people are using mailers which produce this kind of
output. I see replied-to messages quoted in full almost more often than
not on some mailing lists. Often the main content of the replied-to
message is itself a set of earlier messages in an exchange. It is not
unusual to have messages of hundreds of lines with only a few percent
original content.

The large MIME attachments are annoying as well. I suppose if I had a
MIME compliant reader these would just clutter a directory somewhere. This
particular one, application/ms-tnef, is one I see a lot. What is it?
I assume it is added by a Microsoft mail client. Is it a rich-text
formatted version of the message?
