    I run exim with -d, and the things are the same...
exim is runnig the delivery as the user who receive
the mail, so it has permission to write to the file.
Problem is that exim return  a error when it has to
delivery mail to a non-root user.
 The program "test" have 777 mode, so any user
can run it.
