Hi I'd like to change the default email client in kde from kmail to thunderbird. I can change it for my pown account by using system settings / Default applications, and it seems to add a file emaildefaults in my .kde tree, but I'd like to be able to change it system-wide for all my users. Copying that emaildefaults to /usr/share/config doesnt seem to work. Can anyone suggest the correct way to effect this change of email client please. Thanks Roderick
