Just to be more precise, the setting as described have a behaviour that
could not be what one expects:
1) knowing the file name everyone can read it
2) knowing the file name, everyone can delete it

You can fix 1 by setting umask (on the filesystem, if dropbox is in its
own partition) so that actual file permissions are 0640 or 0660.
To fix 2 you should set the sticky bit on the folder. See

Tks to DKG for pointing this out. I'll try to be more precise next time.
