Senderbase is offbase, need some help

Gang,

    I've tried to get the attention of senderbase, which is claiming 
activity from my address space which is in fact either un-routed or 
within dynamic subscriber blocks that have outbound smtp filtering in 
effect. Unfortunately, senderbase refuses to acknowledge the problem in 
their database nor back up their claims with any evidence to the 
contrary other than these ips are listed in their database and that's 
that. I realise this may not strictly be the domain of nanog but I would 
think that quality of services such like senderbase, as measured in both 
false positives as well as their abillity to act on them, would be, 
since many here use and depend on these services. I don't understand how 
or why senderbase would list unrouted address space and further give me 
grief over the reporting of it "Unless the daily volume magnitude shows 
something > 1, I would not be too worried", but accuracy counts and you 
won't have my business unless you can demonstrate some.

Mike-
