[exim] catch all with pdns

Hi,

I was wondering if it is possible to setup a catch all account with
exim for a specific domain.
Let me explain the situation first.

We have a managed dns. A user can make a MBOXFW record in the dns,
then if a mail is send to user@???
exim is looking it up and gets back user@???. That is
working fine.

However if a user sets up *@domain.com everything should go to user@???
. I'am fairly new to exim and I am wondering how and if it can be
setup. If I try that now I get:

node05:/home/tijmen# exim -bt *@jobs4all.ro
R: system_aliases for *@jobs4all.ro
R: virtual aliases for *@jobs4all.ro
*@jobs4all.ro is undeliverable: Unrouteable address

Regards,

Tijmen
