[Exim] relay mail to different port on same host

I am trying to set up an intranet application on a shared server that uses
exim.

I have configured my intranet application to listen for mail on port 26 it
is up and running and accepting mail, but i cant get exim to forward mail
for that domain to port 26.

here is what I have in my exim.conf

Under the transports section i have

#Transport for intranet-domain.com
internal_smtp:
driver = smtp
port = 26

Under the routers config section i have

# Route to pass domain mail to intranet server
smart_route:
driver = manualroute
domains = intranetdomain.com
transport = internal_smtp
route_list = "* 127.0.0.1 byname"
self = send

When I restart exim I get an error saying that manualroute is not found...

What am I missing here?
