spamhaus-ZEN is found but no points are awarded?

[Remco Barendse]

Actually, in my sendmail configuration i use
 	bl.spamcop.net
 	cbl.abuseat.org
 	dnsbl.njabl.org
 	chinanet.blackholes.us
to completely block e-mail coming from these sources (hope i am not 
overblocking but no complaints so far).

I included spamhaus-ZEN in my MailScanner.conf (to avoid generating too 
many lookups which might block me from using the free use policy as i 
heard that people get blocked for anything way below the limits posted on 
their website) and i was hoping that it would improve the accuracy of my 
bayes database.

This means that effectively i only have one list to check by SpamAssassin 
but it should score it.

If nobody is including any scores for ZEN, should i also include that in 
my block lists then instead of using it from MailScanner?

I would prefer to not stop blocking spam at MTA level to avoid the spam 
"hold" storage from overflowing (the mail partition only has 2TB of 
free space) :)
