I like this idea, but wondered about another approach. If you were to
use the lookuphost driver to match each site, and exim were extended to
allow specifying a seperate queue, both for delivery into and for queue
running, this would do what you want, plus have some additional
benefits. I know this wouldn't be quite as nice as your approach above
for your specific case, as it wouldn't allow for the possibility of
direct delivery if the site were connected at the time, but having
seperate definable queues would be more flexible. Maybe the two could be
combined.
