How to increase score of URIDNSBL?

[Roman Volf]

I recieved a spam (http://www.keystreams.com/~volfman/spamd-msg.txt - I 
stripped the X-Spam headers from the message) that only scored a 4.4,
even though the URIDNSBL showed a hit.
Here is the debug from spamd - 
http://www.keystreams.com/~volfman/spamd-debug.txt

Is upping the score that a URIDNSBL hit gives a good idea? I mark spam 
at 5.0. Is this possible?

Any suggestions?
