I googled and found something about editing ~/Library/Preferences/

<key>PreferPlainText</key>
<true/>
Try this:
defaults write com.apple.mail PreferPlainText 1
(This must have been an accessible preference in previous
incarnations, back when I set it.)
You can also set the composing preference in mail to always use plain
text.
