Have Exim lookup each recipient in the Domino directory through LDAP.
Add this to your router.

    local_parts=\
    ldap; ldap:://dominoserver/?mail?\
    sub?(&\
           (|\
          (objectClass=inetOrgPerson)\
          (objectClass=dominoServerMailInDatabase)\
           )\
           (|\
          
(uid=$local_part)(cn=$local_part)([EMAIL PROTECTED])([EMAIL PROTECTED])\
           )\
        )

This should take care of aliases as well as mailin databases.
Make sure you replace yourdomain.com with your actual mail domain.
