If you're running an attractive nuisance, it's simply a matter of time
until someone -does- find you.

ORBS is simply being proactive about it, on advisement from people around
the Internet.

ORBS is NOT damaging your car, your network, or your ability to provide
service. ORBS is merely letting you know that you left your car parked
without the emergency brake on, and that it might roll down the hill and
run over someone when you're not looking. And it's letting people who
might be in the area know too. Yes, this means that someone might give
your car a quick shove down the hill. But it also means people can get out
of the way first. Aren't analogies fun?

ORBS is simply investigating and reporting mail servers which are provable
open relays, and netblocks which are unverifiable due to administrative
choice (either requesting addition to the listing, or by blocking the
testers). It's making use of information that is easily obtainable, on the
suggestion from someone who has probably already checked that you might be
a good choice to investigate (meaning someone has already noticed you, and
you're not hidden from view anymore).

I get regular ORBS probes, and I welcome them. As long as my service is
not directly impacted by those probes (ie. they start bogging down my
systems with tests, or consume a noticable chunk of bandwidth), I'll
continue to do so.

And it's my prerogative to not listen to your mail server if I believe it
is being operated negligently, if I don't believe your mail is RFC
conformant, or if it's tea time. *shrug* ORBS helps me in making my
decision with the first part. I decide if it's tea time by myself. :-)
