[exim] Use of blacklists with white list

I am thinking of using more blacklists
Will this kind of configuration be acceptable?

begin acl

accept dnslists = swl.spamhaus.org
logwrite = $sender_host_address is whitelisted

deny message= rejected because $sender_host_address is in $dnslist_domain\n $dnslist_text
         dnslists= zen.spamhaus.org:surbl:multi.surbl.org
