Exim question - using exim as a simple caching mailserver

[Paul Sheer <psheer@xxxxxxxxxxxxxx>]

I was wanting to know what the simplest configuration
is for using exim as a simple cache. I know I can do it
with:

-----

#################### MAIN CONFIGURATION SETTINGS #####################
log_subject
errors_address = postmaster
freeze_tell_mailmaster = yes
queue_list_requires_admin = false
prod_requires_admin = false
trusted_users = psheer
local_domains = localhost : ${primary_hostname}
never_users = root
host_accept_relay = localhost : *.obsidian.co.za : 192.168.0.0/16
exim_user = mail
exim_group = mail
end

###################### TRANSPORTS CONFIGURATION ######################
remote_smtp:
    driver = smtp
    hosts = 192.168.2.1
    hosts_override
local_delivery:
    driver = appendfile
    file = /var/spool/mail/${local_part}
    delivery_date_add
    envelope_to_add
    return_path_add
    group = mail
    mode_fail_narrower =
    mode = 0660
end

###################### DIRECTORS CONFIGURATION #######################
localuser:
    driver = localuser
    transport = local_delivery
end

###################### ROUTERS CONFIGURATION #########################
lookuphost:
    driver = lookuphost
    transport = remote_smtp
literal:
    driver = ipliteral
    transport = remote_smtp
end

###################### RETRY CONFIGURATION ###########################
*                      *           F,2h,15m; G,16h,1h,1.5; F,4d,8h
end

###################### REWRITE CONFIGURATION #########################
*@cericon.obsidian.co.za  psheer@xxxxxxxxxxxxxx

However, using `hosts', and then `hosts_override' seems like
a hack. Is there a more elegent way, with, say, the lookuphost
driver?

Thanks
