I was trying to minimize the traffic that the KMS SMTP engine generates
when receiving e-mail by looking up the sender's IP address in DNS
blacklists.

I re-ordered the list of DNS blacklist I use like this:

sbl-xbl.spamhaus.org
china.blackholes.us
korea.blackholes.us
russia.blackholes.us

since spamhaus is the one that blocks aprox 70% from all rejected.

To my surprise, the function that checks, does not break the loop when a
positive is discovered. As you can see in the attached log file all 4 lists
are being checked, even though a match is found on the second one and it is
completely unnecessary to check the rest.

1) I am still using KMS 5.7.10. Does anybody know if 6.01 behaves the same?
2) Does Kerio have intention in changing this behavior? I can see no reason
for this.

What I would like to see happen is Kerio scrap the concept of blocking any matches on a blacklist, and instead apply scores to the message, depending on which blacklist it matches. This is how SpamAssassin works and is much more flexible.
