Historical retrospective: MIME recycled the Content-Type header from an
earlier multimedia mail specification instead of using a unique mechanism.
To distinguish between the new and the old mechanisms, the MIME-Version
header was invented.

Consequently, a message with a Content-Type header but not a MIME-Version
header is not MIME.
