Since I am the original poster of this message/thread, I belive you may have 
confused this thread with another of the same subject...

I have made every attemp possible to prevent false positives.  Plus several 
very nice people have contributed whitelists of IP addresses/domains that 
should be exclude from testing.  The SANS server that sends out the DShield 
list is a good example of a dynamic IP address that should not be filtered.  
Haphazard use of DynaStop will only lead to massive mail loss. 

DynaStop does not examine any emails at all, only the IP address based 
solely on patternistic analysis stemming from research I began in 1999. 

In 2005, the IETF realized the importantance of this research and made a 
draft for ISPs to begin moving to a formalized method that seperates  
dynamic and non-dynamic IP addresses: 

http://tools.ietf.org/wg/dnsop/draft-msullivan-dnsop-generic-naming-schemes- 
00.txt 

I do understand your frustration with antispam messures left unwatched.  I 
have been there enough times myself even with a full fledged server. 

DynaStop addresses a very specific type of spam and sets out (through 
concise analysis) to eliminate that spam.
