Where would those additional per-send values be stored?  Currently
dccm has space only for a choice among OK, OK2, and MANY for each
SMTP client value including HELO, IP address, and envelope and header
from values.

Whilelist values of "OK" or nothing for a sender IP address can be used
for a boolean reject threshold.  Do you need more than that?  For 
detecting and stopping "trojaned" systems or other spamming customers,
why do you need more than one threshold?  I can see the utility of
finer control than "trust this user implicitly" vs. a global threshold
for billing and accounting, but do you really need fine controls for
stopping outgoing spam?
