Hi Dave,
I'm breaking this into two discussions as they are two different topics.
The REAL point of Pete's input (and my suggestion) for SNFIPREP is that the
reputation scale of -1 through +1 should NOT just result in either ONE
positive or ONE negative weight option.
Your example:
IPREPUTATION SNFIPREP x 0 10 -5
only result in either a "10" being added or a "5" being subtracted. So you
are turning a continuous scale of -1 to +1 into two discrete values - losing
all the key benefits of having the reputation scale in the first place.
You already have the SNFIP return codes, if someone wanted a "fix" value for
a particular "level" of reputation.
To really make use of the GBUdb, there should be a continuous weight from 0
to 10 for "bad" reputation and 0 through -5 for "good" reputation (using
your sample of 10 and -5).
Basically, for positive GBUdb values, multiply with the "10" (getting a
value from 0 to 10 depending on "how bad" the reputation is), for negative
values multiply with "-5" to get a weight from 0 to -5 (depending on "how
good" the IP is).
This would make the test really useful because it would only cause BIG
weight changes for BIG GBUdb values.
Best Regards,
Andy

Subject: RE: [Declude.JunkMail] Sniffer IP Reputation for "white" listing
As Pete already provided input on this. I am not going to prolix the answer
other than to say when implementing Message Sniffer we abided by the Pete's
advice "Since many legitimate ISPs also produce a lot of spam it might be
useful to apply a bias to this weight so that these systems appear closer to
zero." So currently we do not allow for a negative value as a BASEPOINT,
with that said if you think it is really important to be able to use a
negative value as you have described in your post, let me know and I can add
it to the dev list.
