There are enough horror stories of ORBS everyone on this list knows. The
most simple and stupid thing of ORBS was that people could submit IP's,
and they would test and block it within the hour. If you've ever done a
emergency mail server migration, and was knee deep in DNS and MS hell,
the last thing you need is to have one of your IP's blocked because a
spammer and an ORBS user found your temporary mail server.

Paul, who had the uniq experience of appearing in ORBS with both "blocked
by adminsitrative reasons" and "confirmed does not relay" at the same time.

Port scanning is in violation of some telecommunication laws and even more

The difference is that systems like RBL only block you after they are
convinced the admin can't or doesn't want to be reached. Instead of cutting
you down, they actually try to *help* you fix any problems.
Also stupidity is a very relative term. For instance, migrating and allowing
all local IP's to relay through your mailserver, opens up a subtle hole in
that mail sent to old MX records (so old mailserver) gets a fully granted
relay to the new mail server (because local IP is trusted), so people
tend to forget that portforwarding during a DNS waiting time opens them
up to spammers and ORBSlike actions. Now, I don't MIND people telling me
this, but to immediately ensure that a percentage of my users no longer
can send or receive email for this is plain stupid and wrong.
