permissions all zero when using 'cp'

Dear Gurus,
i recently noticed some errors at my mail-server and so I tried to drill
it down with my limited abilities.
what I found is really strange:
when copying a file (no matter which) the copy gets zero permissions.
looks like that:
root@X:/tmp# ls -altr
insgesamt 20
drwxrwxrwt 2 root root 4096 29. Dez 15:06 .X11-unix
drwxrwxrwt 2 root root 4096 29. Dez 15:06 .ICE-unix
drwx------ 2 mlo users 4096 29. Dez 21:38 ssh-VkxmJ15962
- - -rw-rw-r-- 1 root root 0 29. Dez 21:47 test
drwxr-xr-x 21 root root 4096 29. Dez 22:06 ..
drwxrwxrwt 5 root root 4096 29. Dez 22:22 .
notice the file "test"
root@X:/tmp# cp test test.bak
root@X:/tmp# cp -p test test.bak2
root@X:/tmp# ls -altr
insgesamt 36
drwxrwxrwt 2 root root 4096 29. Dez 15:06 .X11-unix
drwxrwxrwt 2 root root 4096 29. Dez 15:06 .ICE-unix
drwx------ 2 mlo users 4096 29. Dez 21:38 ssh-VkxmJ15962
- - -rw-rw-r-- 1 root root 0 29. Dez 21:47 test.bak2
- - -rw-rw-r-- 1 root root 0 29. Dez 21:47 test
drwxr-xr-x 21 root root 4096 29. Dez 22:06 ..
- - ---------- 1 root root 0 29. Dez 22:22 test.bak
drwxrwxrwt 5 root root 4096 29. Dez 22:22 .
now kindly notice test.bak and test.bak2
whenever I copy a file it ends up with this permission string: "----------"
no matter if I do this as root or as user
this also happens in my maildir, which causes the strange problems I had.
