How to change KMail composer default settings? I use KMail on OpenSuse. How can I store default settings for font, font size, font color, background color and so on in such a way that I get them every time that I open the program? Please consider this fact that I don't have root access in my machine and using another product is not an option here.

From a link given on gmane site:

> It would be nice to be able to click "Load Profile", select "Purist" (loading the fonts from the KDE global settings), then have an option to update the current custom settings to match that profile, and then **tweak** those settings for KMail by checking the "Use custom fonts" check box.
