Yes there should. :) Here's the setup i'm using, with exim-3.16 (built
and packaged by me for my Red Hat 6.x system):

  # /etc/exim/exim.conf: Routers section
  smart_host:
    domains = /etc/exim/smart-domains
    driver = domainlist
    transport = remote_smtp
    search_type = lsearch*
    #                  ^^^^^--- Note the '*' here; perhaps that's what
    #                           Robin is missing....
    route_file = /etc/exim/smart-hosts
    require_files = /etc/exim/use-smart-host


'require_files' allows me to select whether i want to use the
smart_host router or not by touching or removing
/etc/exim/use-smart-host.

In /etc/exim/smart-domains:

!*.my.local.domain
*

In /etc/exim/smart-hosts:

  *:    my.ISPs.outgoing.mail.hub   byname


(I use 'byname' so that i can temporarily use a secondary outgoing mail
hub if the main one isn't working, by adding the right IP address to
/etc/hosts.)

Robin, don't forget to send a SIGHUP to any exim daemons (exim -bd) or
queuerunners (exim -q10m) you might have running after symlinking the
file in place.
