Hi Todd,
Thanks for that. It worked with slight modification. The snippet now:

# Mark it White
warn dnslists = hostkarma.junkemailfilter.com=127.0.0.1
     set acl_c0 = white - dnswl - $sender_fullhost


# Mark it Yellow
warn dnslists = hostkarma.junkemailfilter.com=127.0.0.3
     set acl_c1 = yellow - $sender_fullhost
     message    = X-Warning: $sender_host_address is in a yellow list at $dnslist_domain


# Using the Black List
deny dnslists = hostkarma.junkemailfilter.com=127.0.0.2
       !hosts   = lsearch;/etc/exim/filters/whitelist-hosts
     message    = X-Warning: $sender_host_address is in a black list at $dnslist_domain


# Other Blacklists
deny !dnslists = hostkarma.junkemailfilter.com=127.0.0.1,127.0.0.3
       !hosts   = lsearch;/etc/exim/filters/whitelist-hosts
     dnslists = zen.spamhaus.org : dnsbl.sorbs.net
     message    = X-Warning: $sender_host_address is in a black list at $dnslist_domain


Cheers,
Kerry.
