I got around the problem by changing tip and cu to be both setuid and
setgid to uucp (or whatever group your uucp is in). I changed /usr/spool/uucp
to be group writable (mode 775) and made the following changes. Although this
is not completely bulletproof it is a bit better than having a world writeable
/usr/spool/uucp.
