Yes, the order of the routers seems to be the problem. I've only got four
routers, the two troublesome ones are shown below (in order). I've got a
smart-host-relay setup here, how would I stop system_aliases catching stuff
that isn't for my domain?

system_aliases:
driver = redirect
allow_fail
allow_defer
data = ${lookup{$local_part}lsearch{/etc/aliases}}
# user = exim
file_transport = address_file
pipe_transport = address_pipe

send_to_gateway:
driver = manualroute
domains = +relay_to_domains
transport = remote_smtp
# place the FQDN or IP address of where the
# messages are being relayed to here
route_list = * 172.16.254.254
