[Exim] Default adresses

Hi,

I would like to create a default address for some virtual domains.

I'm using the following director

virtual:
driver = aliasfile
domains = dbm;/usr/exim/virtual/domains
no_more
file = /usr/exim/virtual/alias/$domain
search_type = lsearch

My Lookup file is like this:

#aliasfile for testdomain.co.za
root:me
postmaster:me
nico:me
*:junkie

Mail to root,postmaster and nico is handled correctly.
Unfortunately, if I send mail to jack@???, it is not sent to
junkie

What did I do wrong?

Thanks in advance to all the wisdom on the list.

Nico
