I have a similar setup, and thanks to folks from this list, it's
now working quite well. I have (in /usr/locla/etc/exim/configure):


domainlist  local_domains = "server.host.domain :\
                                      dbm;/usr/local/etc/exim/domains.dbm"



And in /usr/local/etc/exim/domain1.org:

user1:          user_a (local user account)
user2:          user_a
user3:          other@???
*:                 :fail: The user "$original_local_part" does not exist
                             at "$original_domain"



So, if I do:

# exim -bt user1@???,    I get
user_a@???
        <----------  user1@???
        router = localuser, transport = local_delivery



And if I try an undefined address from domain1.org, I get:

# exim -bt nonuser@???
nonuser@??? is undeliverable
The user "nonuser" does not exist at "domain1.org"

The alias files are very flexible, you can do things like:

user_w:         addr@???          # You can forward mail for a user
user_x:         "|/path/to/some/script"  # You can use pipes
user_y:         :fail: No user "user" here!
user_z:         :blackhole:
*:                  user_a
