Yeah. You could do multipart/alternative with the markdown in
text/plain and a rendered version in text/html though.
Personally, I don't think that's worth it (I have my mail client
configured that if I get forced a html email, I just convert it
back to a markdown-looking plain text anyway), and Walter has
complained about the bloat of alternative formats before.
