I use lookup files for virtual domains.

My local_domains setting:
local_domains = \
my.net.au:*.my.net.au:localhost:partial3-lsearch;/etc/exim/clients/domains

Each of my directors has a domains= line for my "real" domains; e.g.
userforward:
  driver = forwardfile
  domains = localhost:my.net.au:*.my.net.au
  no_verify
  check_ancestor
  file = .forward
  filter

I have a custom driver at the end of the Directors section, that
looks up what to do with virtual domains:
#
# This driver handles our virtual domains.  It is
# last, to avoid unnecessary file lookups for real
# local addresses; this is why all of the above
# directors have a "domains = " line.

virtual:
  driver = aliasfile
  except_domains = localhost:my.met.au:*.my.net.au
  domains = partial3-lsearch;/etc/exim/clients/domains
  no_more
  file = /etc/exim/clients/$domain_data
  search_type = lsearch*

/etc/exim/clients/domains contains stuff like this:
*.v-domain1.com.au: file1
*.v-domain2.com.au: file2
*.v-domain3.com.au: file3

/etc/exim/clients/file{1,2,3} contain stuff like:
*: user1@mail.my.net.au

The file /etc/exim/clients/domains just relates virtual domains 
to other files in /etc/exim/clients/, and allows exim to verify 
that a specified domain is a local_domain; the other files in 
/etc/exim/clients, one per virtual domain, act as an aliases 
file for the virtual domain (and can be much more complex than 
the default shown here).  Testing delivery in the example 
above produces:

# /usr/sbin/exim -bt anyone@anyhost.v-domain1.com.au
user1@mail.my.net.au
    <-- anyone@anyhost.v-domain1.com.au
  deliver to user1 in domain mail.my.net.au
  director = localuser, transport = local_delivery


HTH,
