SUMMARY Under "/View/Headers" there is a bunch of options available to display the message header in different ways. I'm not sure if there was an option "Complete Headers" or not, but if so it's gone. The closest I see is "Long Headers", which only changes the design of the headers section, but not the amount of information shown. In older versions of Kmail there was a way to display the complete header information of a message. Where do I find it now? STEPS TO REPRODUCE 1. go to "/View/Headers" 2. choose new header OBSERVED RESULT minor changes in design of header section EXPECTED RESULT at least one option should show complete header information in a simple manner SOFTWARE/OS VERSIONS Linux/KDE Plasma: Chakra Linux Plasma: 5.15.0 Framworks: 5.55.0 Applications: 18.12.2 QT: 5.12.0 Kmail: 5.10.2
