Thanks to Philip and others I now have my ISP style config built and
therefore am posting the final configuration fragments to the list in
case anyone else wants to do a similar thing

######################################################################

# This configuration fragment is for use with an ISP type solution
# Each client has their own directory that contains their own
# editable passwd, alias etc type files. Furthemore if they create
# a local user then that user can also have a a .forward file and/or
# a .autoreply file.
#
# Files and Directories
# Password file for a domain
#	/clients/${domain}/etc/passwd
# Alias file for a domain
#	/clients/${domain}/etc/aliases
# Directory where users mail for a domain is stored
#	/clients/${domain}/mail/
# Location of file with a list of domains
#	/clients/utils/data/domains
