okay, this is helpful stuff. First off, search on
www.debian-administration.org for exim stuff. There are a number of
articles that will get you started with spamfiltering. That's really
pretty easy to set up and you can pipe it all straight to /dev/null
(called blackhole in exim configs). The part that is a little more
difficult, probably, is figuring out who the valid senders are. There
are a number of recipes out there for searching through text files for
valid recipients, or using ldap and other methods for determining who
a valid recipient is. I can't really answer that question. sorry.

nope. not a smarthost configuration. Smarthost is when exim acts just
like an smtp-speaking MUA (thunderbird, sylpheed, what have you) and
it simply routes all mail through a host called a smarthost, further
upstream and that smarthost is the one that actually routes the mail.

sounds to me like you need some ACL magic and then one router
configured that takes all valid mail and sends it on to the exchange

When all is said and done, you'll probably be able to excise a lot of
that sample config out of the way. 

good luck.
