     There is a serious security hole in the 4.3 bsd /usr/bin/uuq
     program that allows everyone to delete anyone's UUCP jobs.

I recommend the following:

     # chown uucp.daemon uuq
     # chmod 101 uuq; chmod g+s uuq

This makes uuq set-gid to daemon.  Then make sure all your uucp jobs
are in files that are readable by daemon but not writable by it.
