[Exim] Exim 4.12 - router should only accept mail form local…

Hello,
I've added a new router to my configuration, which
runs without a problem. But this router should now
accept only mail from local users. I did some testing
but without any success. I hope someone can give me
a hint how to solve it.

Thanks in advance!
