So that users can implement their own policies if desired? So that 
different rules can have a more granular effect on the inbound email 
flow, without this being a simply binary affair (present, not present)? 
More reasons come to mind, but it all boils down to exposing all the 
available information to the users in order for them to make better 

As I mentioned in one of my prior responses, I personally know of 
operations that use that data granularity to their advantage.

I doubt IADB is in a position to dictate to anyone how to use (or not) 
the data it provides. Not SA, not anybody else. Participants in IADB 
(listees and users) voluntarily act so. As someone else in this thread 
pointed out, IADB provides a useful ham signal.

I think the goals of both are fairly aligned. An antispam solution is 
not good if it blocks wanted email. IADB is conveying information about 
the stated policies / practices of the sending organization. Assisted 
with this information, SA can take better decisions about specific 
pieces of email.

I fail to see how SA is acting as a facilitator in this case. SA ships 
with rules that look up all the available information about a piece of 
email and then, hands this information to a set of rules that decide 
what should happen to that email. You're objecting to the scores being 
applied to those rules because you received one email that you believe 
doesn't align with the results of one of those rules and want to drop 
those rules from the distribution.

What would happen if the email you wanted came from a mail server listed 
in Spamhaus? Would you then argue for removing rules using Spamhaus from 
SA altogether?

I would urge you to follow the advice of other list members and actually 
report the misclassified spam so that involved parties can take action.

In this case it seems to me that you already have a desired outcome and 
will grasp at any shred of argument to justify it.
