It's your ISPs outbound smtp server. The idea is you can set your MTA to
forward all outbound mail to it and it'

This is what I'm now using w/Postfix (should work for any MTA):
header NO_RDNS Received=~ /\(unknown[ ]\[/
describe NO_RDNS Sending MTA has no reverse DNS
score NO_RDNS 2.5
header NO_RDNS2 Received=~ /\(\[.*\]\)/
describe NO_RDNS2 Sending MTA has no reverse DNS
score NO_RDNS2 2.5

Hello,
I've noticed that Columbia University has an SA rule for no reverse DNS:
CU_NO_RDNS on http://www.columbia.edu/acis/email/filters/spamscore.html
Does anyone know how to implement this rule?
thanks
