Sure that you used the configuration shown above? At least the router
"ldap_alias" does not appear in the output.
Try "exim4 -d-all+route -C …", it's not as much output.

"one_time" prevents an alias from resolved again and again on for
several delivery attempts.
I think, you should try to add an extra attribute to your LDAP
directory, "mailPrimaryAddress" or something similiar. I'd say you can't
even rely on a specific order of the returned values for the "mail"
attribute. Or you can calculate the primary address from other
attributes of the specific user.
