Re-reading that, I disagree.

It is entirely possible (as stated explicitly in RFC2045) for a MIME 
entity to contain unencoded binary data: any arbitrary stream of bytes. 
Email normally cannot, but that's a transport issue. Since the 
BINARYMIME extension for SMTP exists, it is even possible to send mail 
(with some MTAs) as an arbitrary stream of bytes.
