[exim] Mixing Manualroute and Redirect router skills

Hi alls,

I'm trying to set up the following scenario.

Exim eats a mail and, if $header_foo == 'bar', then it forwards the mail
to a remote smart host.

To filter the mail, I need a Redirect router, where i can define an Exim
filter. To redirect it to a smart host, the Manualroute router is simply
wonderful.

Now, how can I mix the "smart host skill" and the "filter skill"?

Do I have to use a Redirect router with a pipe command inside the
filter, dropping the Manualroute router?

In this case, if You have some good ideas, which command can I use to
forward the mail to the remote smart host?

Thanks in advance
