When viewing messages, the font in the message body does not conform to the Font DPI settings in KDE.
Everything else does, except that one part. The image doesn't quiet justify it as I am on a 4K screen, but you should be able to notice the differences in font size. On my screen it is impossible to read.
Steps to Reproduce:
1. Set Font DPI settings to a higher value.
2. Open Kmail on High DPI screen
3. Select message or open it in window
4. Obverse that message body does not conform to the Font DPI settngs
Message is imposible to read due to extremely low fonts
Message body should conform to Font DPI settings in System Settings
I can confirm this on openSUSE LEAP 42.2
Screenshot please from font configurate in kmail + font from system + messageview after settings them please ?
it's wierd as we use QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling); so it seems ok.
I can confirm this on openSUSE LEAP 42.2, too.

there are alos screenshots attached.
This problem makes KMail pretty much unusable with high DPI. Not only is the font too smal, but also the mouseclicks don't end up correctly. It's hard to show in a picture, but should be pretty easy to reproduce.

Exactly the result here as well.
What is your kmail version + qt version ?
