If you're using Taylor UUCP 1.05, you'l have to change the following flags
in /usr/src/gnu/libexec/uucp/common_sources/policy.h :
------------------------------------------------------------
/* If your system does not support saved set user ID, set
HAVE_SAVED_SETUID to 0. However, this is ignored if your system
has the setreuid function. Most modern Unixes have one or the
other. If your system has the setreuid function, don't worry about
this define, or about the following discussion.
If you set HAVE_SAVED_SETUID to 0, you will not be able to use uucp
to transfer files that the uucp user can not read. Basically, you
will only be able to use uucp on world-readable files. If you set
HAVE_SAVED_SETUID to 1, but your system does not have saved set
user ID, uucp will fail with an error message whenever anybody
other than the uucp user uses it. */
#define HAVE_SAVED_SETUID 0
/* On some systems, such as the DG Aviion and, possibly, the RS/6000,
the setreuid function is broken. It should be possible to use
setreuid to swap the real and effective user ID's, but on some
systems it will not change the real user ID (I believe this is due
to a misreading of the POSIX standard). On such a system you must
set HAVE_BROKEN_SETREUID to 1; if you do not, you will get error
messages from setreuid. Systems on which setreuid exists but is
broken pretty much always have saved setuid. */
#define HAVE_BROKEN_SETREUID 1
------------------------------------------------------------
It should work much better after that.
Beware there is another bug in 1.05 that I fixed a few months ago. When it
has to create a destination tree (e.g. you asked to put a file in
~////path///with/multiple/slashes/) it failed. Here is the patch :
/usr/src/gnu/libexec/uucp/libunix/mkdirs.c
