[Exim] *@domain to single users for multiple domains...

    Can (and will) anyone tell me how to setup the conf file to allow
handling *@domain.com for multiples domains, to multiple user accounts.

    At the momment we only have one user using this, so I just
hardcoded it into the conf file using a smartuser director; lazy I know,
but does anyone know how to do this neatly for the multiple senario?
