[exim] transport to another smtp

Hello list

I am searching for possibility to relay incomming mails to another smtp
like this:

I'll have a list of mail adresses, which have to be redirected to
another smtp's

-------------------
#File /etc/mail/exim/redirects
mail@???    another-smtp-ONE.my-domain.foo
mail2@???    another-smtp-THO.my-domain.foo
-------------------

I tried to handle this thrue aliase, but it ist not that, what I will.

Need I just a router to handle this ?

Have somebody solution for my problem ?


Regards
Stan
