From http://www.hylafax.org/troubleshooting.html ::

"Note that hfaxd uses the chroot system call to confine clients to the HylaFAX 
spooling area on the server machine. On most systems only the super-user is 
permitted to do a chroot call so if hfaxd is not started by the super-user or 
the executable program is not setup to be setuid-root then it will not function 
properly. If this happens clients will usually be denied access with a message 
of the form ``Cannot set privileges.''."

So... first of all, is hfaxd running as root?  If not, then that's a problem - 
because if you applied the recent hfaxd-vulnerability.patch, or if you are 
using current CVS, then you'll have to 'chmod a+s hfaxd' in order to get it 
functioning again.  I think that the preference is for you to run hfaxd as root.
