Yah, I've been advocating the use of a CIDR match-list from the beginning
for this and other reasons. Actually what you'd want is per-entry
weighting, so for me and my mailbox:

  CIDR 221.232.0.0/14 score = 3.0
  CIDR 147.28.0.0/16 score = -3.0

The ASN matching has merit too, so maybe:

  ASN 4134 score = 3.0
  CIDR <holes punched> = -3.0

etcetera
