Let me rephrase then: Qt5 applications, including Kontact, follow Qt font 
settings, which in Plasma can be configured through Plasma's System Settings, 
in Gnome, if Qt Adwaita platform theme is installed, follows GNOME font 
settings which can be configured through GNOME Setting. On Windows and Mac it 
follows system-wide font settings that can be configured through corresponding 
platform font configuration tool.

Ah, sorry for misunderstanding. In that case there's nothing to discuss, you 
can still customize that: Settings -> Configure KMail -> Appearance -> Font -> 
Apply to: Message List

The only thing you can't change is different font family or size for read, 
unread etc. messages.

Not even a style can override QFontDatabase::GeneralFont :-)
