ORBS has simple and consistent policy "be probed or be listed". Read the FAQ,
pleeease.

Not all sites they cannot probe. Only when there are information that sites
(or their ISP) are intentionally block ORBS's bots.

Let. Me. Repeat. Once. More. As. Far. As. You. Are. Not. Interested. In.
Sending. Mail. To. Linux-Kernel. Mailing. List. Or. Few. Top. Developers.
Like. Cox. Or. Rik. You. Can. Do. Anything.

You are right :-) They are not blacklisting sites just since SMTP connection
was rejected :-) They ARE blacklisting sites only when it's clear that said
sites are blocking ORBS's bots. It's done by humans, not by bots and thus it's
MUCH harder to pull host out of such "manual" blacklist (bot will NOT remove
you from said blacklist even if you are stopped blocking - human should do this).
MA> Plus, I've seen so many defective relay probes...
If you found bug in ORBS's bot then say about it, do not hide it :-) They are
more then willing to fix bots if they are really broken. BTW ORBS bot will not
just silently add system to blacklist - it'll send message to postmaster about
accident with clear explanation of vulnerability and istructions to pull out
system out of blacklist when vulnerability is closed. Unfortunatelly first
reaction for decent amount of "sysadmins" on such message is just blocking
ORBS and sending message to ORBS "I'm not open relay anymore, pull me out of
you #$@%$ blacklist". So said policy really needed. Sad but true.
