Once upon a time I had a lot of respect for Alan Brown and ORBS.
Now he's spent so long fighting spam that it's warped his perspective: if
you aren't pro-ORBS then you're obvious either a spammer yourself or you
just don't give a damn about network security. The possibility that
people can be anti-ORBS simply because Alan Brown personally rubs them up
the wrong way isn't worthy of consideration...
Alan: please stop pretending that ORBS can ever be perfect; in a world
with very short-term number assignments between independent parties (DCHP
on dial-up and similar), there's no way you can make it so. On the one
hand the DUL says that all dial-up users must direct their outbound mail
via their ISP's SMTP server, but on the other hand if one of the dial-up
users runs an open relay, the ISP's SMTP server will be placed on the
blacklist -- and on a "one strike and you're out" basis!

ORBS is suppose to target the people responsible for the traffic eminating
from an IP number, since users of ORBS only see the results for the single
IP number they're checking. They don't go and look at whole netblocks to
see the bigger story, so incorrectly asserting that the machine behind a
particular IP number is a spam haven is a libel on the operator of that
Somehow there seems to be a lack of understanding by the ORBS maintainers
that an entity as provider of a number-range should be treated separately
from that same entity as user of *some* of those numbers; not to do so is
just petty politics of the worst kind: "if you don't comply then not only
will we blacklist the IP addresses of your machines, we'll try to chase
away your customers who are using completely separate IP addresses".
I regard this latest episode with Telstra as a very serious breach of
public trust by ORBS; even if blacklisting Telstra's own machines is
justified, it is simple laziness to blacklist the entire number range
rather than those individual numbers which are demonstrably Telstra's
machines. And if Telstra assigns a netblock to some other entity who then
runs an open relay, then it is that other entity which should be
blacklisted, not all of Telstra's customers. Otherwise where does it end;
blacklisting APNIC's 220.127.116.11?
This travesty of justice is by no means new, merely on a larger scale from
what ORBS has already done before: I have a telehoused box (which I've
always taken great pains to ensure is "orbs compliant") that last year was
put on ORBS blacklist because one of the other machines on the same /24
was a relay. Somebody at ORBS assumed that all IP addresses in the /24
were operated by the same entity, and added the lot to the blacklist.
If it had been changed promptly when it was explained that these addresses
were mostly operated by separate entities, then I've have just put it down
to overzealousness, but that this situation persisted until a few months
ago shows that it was simply petty politics trying to force compliance of
a few machines by scaring away their owners' customers -- even people who
had no dealings whatsoever with the noncompliant machines.
I'm pissed off that ORBS has sullied my reputation simply by association
with people I happen to be in the same /24 with; ORBS decided somehow they
were my responsibility. Like Ben Elliston said: there's something wrong
with this picture.
