Email is whatever you say in the header it is. It should be plain text or at least one of the multiplart/alternative parts should be plain text, but it does not have to be. I can send you an email whose BODY will be a GIF image if I feel like it. How would your mail client handle it is a different question but it will be a proper MIME encoded email.
