re: MIME-Version is useless

I disagree strongly with this sentiment. If there is no MIME-Version:
header, the message is not in MIME format, and expecting the Content-*:
headers to be in comformance with the MIME format when there is no
MIME-Version: header is asking too much. The Content-Type: header has been
around for a LONG time, and many providers have done various things with it.
Unfortunately, these things are NOT necessarily compatible with MIME.

If it doesn't say it's MIME, then it's not MIME. Sorry, but it's true.
