ORBS catches far more than MAPS.
As Randy stated "so does a hydrogen bomb". The problem is target acquisition
and [the lack of] discrimination. The REASON tactical nukes aren't used
regularly is the collateral damage issue.
My take is that anybody who has a
problem with the infrequent ORBS probes should have a huge
problem with the daily bombardment of relay attempts.
A system that tests positive for ORBS , yet is using MAPS, will not be used
as a spam relay. Yet, ORBS will list such a system.
Bottom line: Blocking mail from rogue servers is the best way to stop
spam and to not be a party to somebody else getting
relay-raped. Anyone with clue closed relays how many years ago?
It is more accurate to state that most folks have placed guards on their
I don't buy the "we need open relay for nationwide users" argument,
either. Build a cheap MX that does nothing but take mail from a given
POP, and send it to the world. Anti-spoofing at the border,
don't accept mail from the outside world, and you're done.
You must not have a roaming staff or are willing to keep telcos wealthy.
