[exim] forwarding *@domain to one person

Hi All, The mail server handles a hundred or so domains.
Some users are aliased in the aliases file and some are
cyrus users. The owner of the company wants *@thisdomain
to be forwarded to him. Aside from I don't like this very
much - I don't have a good idea about how to do it.
Thanks for any help
