Then, next step is to go to the "Compose." Tab. Click on "Font Settings" for Mail. (Don't confuse this with "font settings" for "News". You don't need to change the font settings for News, unless you want to.)

Set this up exactly like the right.

Once again, don't forget to click on "OK".

Go to the next page.
