remote exmh from Mandriva 2010.0 X session

As usual I started exmh on a remote host via ssh.  This was on a 
freshly installed Mandriva 2010.0 system.  I got the error:

  BgRegister X server insecure (must use xauth-style authorization)

'xhost' showed that localhost was allowed insecure access to the X 
server.  The source of this was in /etc/X11/xinit.d/msec which 
contains this on my system

  /usr/bin/xhost + localhost

I changed the "+" to a "-" and the problem went away.  But, an hour 
later the "-" changed back to a "+".

Does anyone know how to stop the reverting of the xhost command 
option in that file?

Thanks....
