[Exim] Smarthost + Queueing.

If i want to use a "queue only" approach, in conjunction with a smart host.
Would the following suffice

(global)
queue_remote_domains = ! *.mydomainame.se
queue_only_file = remote/usr/exim/linkdown.flag

(roters)
route_append:
driver = domainlist
transport = remote_smtp
route_list = "* smtp.at.my.isp.se byname"


Would that deiver everything thats local immediately, while sending all
remote mail when i do a queuerun, and (assuming i remove the lockfile) let
anything received by the server be procvessed while the link is up?

Or am i missing something?
