Greetings -
I've made a little progress, but am still having problems.
Please can someone give me any advice: my deadline is really close now!

I thought I had found the variable I needed: $sender_host_address
contains the numeric IP address of the host transmitting the incoming
message, or is empty for a locally submitted message.
So my first two routers now read:
================================================
# This router sends all locally originating messages to a central
smart host.
send_local_origin_to_smart_host:
driver = manualroute
route_data = ${if eq{$sender_host_address}{} {mta.york.ac.uk} {}}
transport = remote_smtp
# This router routes all non-local addresses to a central smart host.
send_to_smart_host:
driver = manualroute
route_list = !+local_domains mta.york.ac.uk
transport = remote_smtp
================================================
where "mta.york.ac.uk" refers to our mailhubs.
Whilst this works it causes the problem that a message which can't be
delivered isn't getting deferred and queued for re-try, but instead
the failure notification is sent back immediately.
I'm surprised by this and don't understand why it is happening.
Can anyone help me get locally-submitted messages (including delivery
failure reports) to be routed to our mailhubs, but messages arriving
using SMTP over TCP/IP to be delivered (and deferred/queued if the
recipient's quota is full!).
Panicking slightly now...
