# CIDR (Classless Inter-Domain Routing)
# Generate partial regexp patterns for every possible IPv4 NETWORK/CIDR
# pattern from /8 to /32 related to the IPv4 address we are looking at.
#
# This file is written entirely in procmail. Yes, I know it's re-inventing the wheel
# however this may be the only way to ensure maximum backward compatability with
# the various older operating systems using the SpamBouncer. -GE
