but it's installed by default and I use it on my server so I'd rather 
not have to learn something else as well.

I have now found a relatively simple config change which works

I just added "self = send" and removed "domains = ! +local_domains" to 
my smarthost router

I /think/ this leaves things intact so that I can still use the 
exim4-config package :-)

   debug_print = "R: smarthost for $local_part@$domain"
   driver = manualroute
   self = send
# domains = ! +local_domains
   transport = remote_smtp_smarthost
   route_list = * DCsmarthost byname
   host_find_failed = defer
   same_domain_copy_routing = yes
