Hi,

I found some more info, the addresses from the dns are parsed into a  
local file which has the format:
  *@jobs4all.ro                            t.w.k.demes@???


So exim finds the * adress in the local file then does a lookup to see
if the email adress exists.
Still my question remains how do I make exim respond to the *
correctly instead of giving me back:

raar@???
    Unrouteable address
