[Exim] host_reject not used?

In my exim-3.36 configuration I have instituted several anti-spam
measures. I have two lookup files set up by:
sender_reject_recipients = @@lsearch;/etc/exim/spammers
host_reject = @@lsearch;/etc/exim/LARTed

The format for each of these files are:
spamdomain.com
hotmail.com
iwanttospamyou.com
and
64.4.31.4
65.118.64.0/22
66.21.5.90
respectively.

However when I try 'exim -d9 -bh 64.4.31.4' to simulate a connection from
hotmail, I see this:
Exim version 3.36 debug level 9 uid=0 gid=0
probably Berkeley DB version 1.8x (native mode)
Caller is an admin user
Caller is a trusted user
originator: uid=0 gid=0 login=root name=Charlie Root
sender address = root@???
sender_fullhost = [64.4.31.4]
sender_rcvhost = [64.4.31.4]

Have I misconfigured host_reject and sender_reject_recipients? Or am I
missing something more fundamental?
