This worked for me, YMMV. (SME7.0rc1)
#yum --enablerepo=base install ghostscript sharutils
#wget
ftp://ftp.hylafax.org/binary/linux/redhat/RPMS/i386/hylafax-4.2.5-1rhel4.i386.rpm#rpm -Uvh hylafax-4.2.5-1rhel4.i386.rpm
Run /usr/sbin/faxsetup
Run /usr/sbin/faxaddmodem
#mcedit /var/spool/hylafax/etc/hosts.faxd
And add your local network details to the bottom of the file example:
192.168.50.*
#cd /etc/rc.d/rc7.d
#ln -s /etc/rc.d/init.d/hylafax S92Hylafax
For receive enviroment create custom template
#mkdir -p /etc/e-smith/templates-custom/etc/inittab/
#mcedit /etc/e-smith/templates-custom/etc/inittab/75hylafax
Add the following to this file:
t1:23457:respawn:/usr/sbin/faxgetty ttyS0
#/sbin/e-smith/expand-template /etc/inittab
Re-read init
#init q
And I use WHFC for the clients
