[exim] How to forward outgoing mail to specific email accoun…

Hi all,

I am researching two day for my question. I want to filter all outgoing
email from specific domain to email admin@???. I find this tutorial
via link
http://www.instacarma.com/blog/technical/how-to-set-up-a-forwarder-for-outgoing-emails/,
but it's not match my require. Because, I want have separate filter
file
not one file /etc/cpanel_exim_system_filter.

Please help me solve this problem. And I am sorry for my bad english.
Thanks!
