[exim] Frankenstein exim.conf

I have tweaked exim.conf so many times over the years, that I am
concerned something(s) are completely disfunctional. For example I have
been receiving spam from servers blacklist by mcafee & barracuda,
reviewing the logs, I find neither blacklist has blocked any message.

Comments on this situation are appreciated. My acl follows:
############# ACCEPT SETTINGS#######################
begin acl

acl_check_rcpt:
accept hosts = lsearch;/etc/exim/whitelist
accept hosts = :
deny local_parts = ^.*[@%!/|] : ^\\.

          endpass

   deny senders = :
