[hylafax-users] New faxrcvd



I have finished working on a new faxrcvd. Have a look and if you like what you
see, by all means use it. I have made a lot of changes so I decided to post the
whole file instead of just a patch. -Jeremy

FATAL ERROR: $SPOOL/etc/setup.cache is missing!

The file $SPOOL/etc/setup.cache is not present.  This
probably means the machine has not been setup using the faxsetup(8C)
command.  Read the documentation on setting up HylaFAX before you
startup a server system.
