[Exim] forwarding to localhost:10025

Hello list,

My Mailserver exim 4.12 works perfectly.
But I need to forward all mail to another mailserver
on the localhost, port 10025.

I put in my exim.conf

smart_route:
driver = manualroute
domains = *
transport = remote_smtp
route_list = * "127.0.0.1:10025" byname

But the message is frozen:
"remote host is the local host"
"== my@??? R=smart_route defer (-1): remote host address is the local host"

Of course, it is the localhost! But I need to forward all the mail
on the localhost to the other port 10025.

Thanks for any help appreciated.

Thomas.
