1. pref("mail.asksendformat.default", 1); //1=plaintext, 2=html, 3=both
   This define the default action selected when the dialog open. This could be overwritten by the preference
   mail.asksendformat.recommended_as_default (described here after)


2. pref("mail.asksendformat.recommended_as_default", true);
   If you set this preference to true and we have a recommended action, this action will be selected by default.
   In this case, we ignore the preference mail.asksendformat.default

 
3. pref("mail.asksendformat.display_recommendation", true);
   When this preference is set to false, the recommended action label will not be displayed next to the action
   radio button. However, the default action might be change to the recommended one if the preference
   mail.asksendformat.recommended_as_default is set.
