[Exim] special user lookup

Helo.

I am trying to set up exim to look not for local users,
but in a cusom file created and maintained with htpasswd.

I had this conf in v3.x , but it does not work in 4 anymore.
I have read faq's and pdf, but cant get it to work...

I know how the routers and transports work, but I just cant seem
to get it to work.
Please can someone help ?


Here is my old confs:

TRANSPORT:
virtual_localdelivery:
driver = appendfile
create_directory = true
directory_mode = 700
file = /var/spool/virtual/${domain}/${local_part}
user = mail
group = mail
mode = 660


DIRECTOR:
virtual_localuser:
driver = aliasfile
file_transport = address_file
pipe_transport = address_pipe
transport = virtual_localdelivery
domains = lsearch;/etc/virtual/exim_local_domains
file = /etc/virtual/$domain/passwd
search_type = lsearch
no_more

Thanks.
