You have an old version (it's up to version 2.0.x). But, see if you have 
this feature:
Edit > Account Settings > (pop account) > Composition & Addressing
There's a checkbox there: "Compose in HTML". I think that should do it; 
mine is not checked, and I never send in html (even tho I reply to html 
emails).
