It can't be that specific.  There must be some way such as a header
regexp that searches for "unknown" or the lack of a DNS name:

header NO_RDNS Received=~ /unknown/
describe NO_RDNS Sending MTA has no reverse DNS
score NO_RDNS 2

header NO_RDNS2 Received=~ /\(\[*\]\)/
describe NO_RDNS2 Sending MTA has no reverse DNS
score NO_RDNS2 2

Anyone?
