[exim] exim4 with simple virtual hosting

Hi,

i think this question is answered many times, but i searched the list,
the net and the documentation. I found one thing in the documentation
that sounds like what i want, but i does not do what i want.

I simply want to have a file where i add a line like this

webmaster@??? user
webmaster@??? anotheruser

you see what i want, a simple address to local user mapping. I added
this router:

my_domains:
debug_print = "R: my_domains for $local_part@$domain"
driver = accept
domains = dsearch;/etc/mail/domains
local_parts = lsearch;/etc/mail/domains/$domain
transport = LOCAL_DELIVERY

and i created the directory /etc/mail/domains and add a file for my
domains and wrote down the above things (seperated by domains of course).

--- the file /etc/mail/domains/domain1.dom --
webmaster user
---

The router is called before the local_user router and processed, it
found the dir/domainfiles but it does not transport the mail to the
correct mailbox, it just leaves the mail as it is and want it to deliver
to the user webmaster which doesnt exists.. Here is the debug out for
this transport
