Not when they are the text portions of the message. If you look at a complex raw email message, there may be several message parts. These can be BASE64 encoded files of any type. All the message parts are essentially contained in the message body. It is up to the client application to separate these parts and reconstruct them into their original formats. I am seeing several hundred spams a day where the sender sends an adult message from an innocuous email address with a subject like "Got your message". The message bodies may be extremely explicit, so they are BASE64 encoded so that they get by spam filters or "rules" like those available in iMail. There would be no good reason at all to encode message text except to get by these filters.
