[exim] block domain sender

Hi

I'm trying to configure exim to deny domain sender that appears in to my
blacklist, but don't work.

In to acl_check_rcpt I've write the follow lines:

  deny    message       = Rejected because $sender_host_address is in an
internal blacklist
          senders       = lsearch;/etc/exim/blacklist.cfg

In to the file I've write a simple entry for test:

hotmail.com
*.hotmail.com

I've try to send mail from hotmail and it pass.

This is an example of the my mainlog.

I've try to make a deny with condition, without success. :(

How can make the block?
