Excellent, thanks - That gave me the clue I needed - I've now got it
working with mysql:
conditional_forward:
driver = manualroute
domains = +local_domains
local_parts = ${lookup mysql{SELECT user_localpart FROM
exim_forward \
WHERE user_localpart =
'${quote_mysql:$local_part}' \
AND forward = '1'}}
transport = remote_smtp
route_list = * remote.server1:remote.server2
