Debian – Address rewrite on Exim4 Light not working

I'm running the package exim4-daemon-light on Debian Lenny to send emails from my website.
My intention is to redirect emails to an specific mailbox on test environment.

The example on documentation is not working for me. I tried this rewrite rule (Located in /etc/exim4/conf.d/rewrite/31_exim4-config_rewriting):

*@*.hidden $1@hidden.com fsrF

And reload the configuration:

vanilla:/etc/exim4/conf.d/rewrite# invoke-rc.d exim4 reload
Reloading exim4 configuration files: exim4.

And test with as root:

# exim -brw someone@random.hidden

The result is:

  sender: someone@random.hidden
    from: someone@random.hidden
      to: someone@random.hidden
      cc: someone@random.hidden
     bcc: someone@random.hidden
reply-to: someone@random.hidden
env-from: someone@random.hidden
  env-to: someone@random.hidden

It seems that the rewrite rule is not been loaded. Even when I write some garbage in the file nothing happens:

### rewrite/31_exim4-config_rewriting
