[Exim] ACL formats

Experimenting with deny hosts under acl_check_rcpt, to shut out some
spammers.

If I've got a text file in this format:

65.124.104.0/24        # Aibusiness.net, etc. CopyDVD spammer.
65.124.105.0/24
65.124.106.0/24
65.124.107.0/24
65.124.108.0/24
65.124.109.0/24
65.124.110.0/24
65.124.111.0/24
206.239.10.142        # Reply.net

etc., which is the appropriate lookup type to use?

Would lsearch work if I terminate the entries before the #'s with a : ?
