In KMail 1 it's possible to set folders to display html, so you could

I know that more html support is planned for KMail 2 but I don't know
how far it has got.
Really??? I didn't know that was possible on a folder-by-folder basis! I
think it would also be neat to be able to specify on a recpient-by-
