That's because these lists are really "or" lists; it's a local domain if
it matches the first item OR the second item OR ... so putting a "not"
in there doesn't do what you want, since you want an AND construction.
You need local_domains_except (which doesn't exist, and would be nasty
to implement, because local_domains is checked in a lot of places).

I don't understand.

Off the top of my head:
# Don't have any hard-coded local domains; initially Exim thinks
# everything is remote.
local_domains =
# A special router detects the true local domains
detect_local_domains:
driver = domainlist
domains = *.cs.huji.ac.il
except_domains = partial-db;/cs/exim/db/subdomains
route_list = "* 127.0.0.1"
self = local
Yes, it's a horrible hack!
