Here's what I did to make the ramdisk.
in /etc/lilo.conf
add the line (up in the top section) 
ramdisk=500000 (that makes a 500meg ramdisk, change for your use)
then in rc.sysinit, before all the drives mount, I have
mke2fs /dev/ramdisk   (that's what redhat 7.2 creats the device as)
after that I have the ramdisk listed in fstab so it get's mounted normally
and after the mounting (still in rc.sysinit) I have
chown defang.defang /var/spool/MIMEDefang (because that is the user that runs 
mimedefang).  Run lilo and reboot; that works for me

There are other ways to do it; but that is my method.  If you need any more 
info, send me an email.
