I already know that. I'm running Kmail on DragonFly now.

What's the difference?

I don't understand X cookies, but I tried again and it worked:
bash-4.2$ xauth nextract - $DISPLAY
0100 0011 6461726e65722e6978617a6f6e2e6c616e 0001 30 0012

bash-4.2$ ssh -Y chausie

phma@chausie:~$ xauth nextract - $DISPLAY
No matches found, authority file "-" not written
phma@chausie:~$ xclock&
[1] 11334
(I ran kooka directly on chausie already and scanned what I needed.)

I believe in Yellow when I'm in Sweden and in Black when I'm in Wales.
