HTML never has embedded binary data and all E-Mails are

mime-encoded in general (nowadays).

A HTML mail is divided into several mimeparts.

There is one part containing the HTML text and other parts containing images.

The HTML part references its images via an Content Identifier

(CID:) in the <img> tag. The MIME part which is marked with this CID holds

the (Base64) encoded binary data of the image.

Have a look into an *.eml file :-)
