I just have one question. I'm using ZD to manage my free Yahoo! Webmail account, and just became familiar with this very recently. One thing I have noticed is that for the most part, it seems that nearly all of my incoming mail messages seem to be displayed in a very similar type of serif-font, one which I do not particularly care for (maybe I'm being too picky, I don't know).
However, thus far after running many a search, I have yet to find a way to modify this setting. I know I can modify the font on my my outgoing mail, but what about the incoming mail?
