Bob,

First...the knujon site clearly states: "Return forged email to
original sender", so yes, forgery most assuredly has a relationship
to this conversation since it's apparently what knujon does, at
least according to knujon. True, packet shaping is not involved
here...I said it's a better solution than this one...which, no
matter how much I read keeps coming back to "we'll fire emails at
the genuine sender of your spam...isn't that great?".
Anyway...

I think the biggest point missed here is this:  The sender you
identify...99 out of 100 times, is not the twit who is actually
doing the spamming.  Nowhere in the header will you be able to
parse out
"JohnSpammer@Not_this_poor_bastard's_Box_I_really_run_This_Box.com".
The sender you identify is some poor end user or clueless sysadmin
who got their box/server owned.  At best, given what you just said,
you are doing no more than SpamCop already does, yes?

On we merrily go...

Bob, help me understand why it is you feel that ICANN will somehow
respond to you and shut down the domains where spam is comig from,
please.  Where it's coming from is NOT a mystery...hasn't been in
ages.  A quick trip to spamhaus will handle that for you.  I know
who those domains are, everyone on this list knows...or can know
with trivial effort...who those domains are, and ICANN sure as hell
knows who those domains are.
<http://www.spamhaus.org/statistics/networks.lasso for the curious
but lazy>

Why should any of us think that somehow this new service has more
cred with ICANN or the ISPs than spamhaus, spamcop, et al?  We who
get to try and stop this crap from flooding mail servers have been
reporting for quite some time now...and funny, I don't see ICANN
shutting down MCI, SBC, Comacast, level3, or any of the rest of the
top 10.  The simple fact is that ICANN's not going to shut them
down...and it wouldn't matter if they did.  That's right...would
not matter.  If one compromised machine that is being used as a
spam generator goes dark, do you really think they real spammer
won't just find a new one?

As I said in the first email, you are going to return mail to the
"actual sender" and I guess, the sender's ISP...who is in reality
not at all the actual sender.

Last but not least..I love the "if you don't agree that we know THE
WAY it's only because you don't get it...but that's ok, most people
don't...just trust us." bit.  You're right, none of us on this list
can grok "KnujOn has a special algorithm that finds out where the
email is
really coming from and then returns the email to the sender."  Yep,
that sure as hell is rocket science (ok, where is that guy from
nasa we had here...maybe he can help us out) Bob.

Anyway, I've burned enough cycles on this...

Cheers,

Bart

Hi Bart,

 Sorry but you missed a few points. The mail you would forward
will be
sorted so that only one email goes back to the source. Next the
source
will lose its domain registration if they do not follow the ICANN
rules,
which is most spammers. In general, they do not tell the truth nor

do they
behave responsibly.

Packet shaping and forgery have no relationship to this.

The experience so far is that no one gets it the first time
around and
very few of them after some effort. It is not like any current
approach,
so don't feel bad. It is a very good idea, once it's understood.

There is no real increase in mail from KnujOn, but the decrease
in spam
received has been proven in alpha testing. Your filter, we'll take

it from
there.

            cheers, bob

Bob,  took a little trip to KnujOn, and have a comment or two...

From the site, with comments parenthetically inserted inline:

_________________________

I already have a spam filter/blocker, why do I need KnujOn?

Filters and blockers stop spam from reaching mailboxes but do
not
actually stop the flow of spam. The messages pile up and must be
reviewed and deleted. Would it not be nice to just dump all the
messages in a program and have them returned to the sender?
(Collecting and bouncing back all of the spam certainly does not
block the flow of Spam either...in fact, you just doubled the
traffic and if the actual sender is a bot'd machine, all you are
doing is needlessly conjesting the 'net and not doing anything
to
the spammer.)

How is KnujOn different from current anti-spam programs?

Filters and blockers search emails for keywords and other
content
that flag messages as possible junk mail and then divert the
email
to a quarantine area for review or deletion. KnujOn takes junk
email and returns it to the sender.  (Sooooooooooooo, you have.a
bounceback routine when you find a forged sender....see
above....returning to sender is bad, Bob.  A better approach
would
be traffic shaping, which of course is already being done
elsewhere
by others, which throttles the spam and forces it to time out.
Of
course, just nuking the stuff before it hits the mail gateways
is a
tried and true approach as well)

What does KnujOn do?

KnujOn has a special algorithm that finds out where the email is
really coming from and then returns the email to the sender.
KunjOn
also collects information about junk mailers and detects
fraudulent
Internet activity, alerting possible victims before damage is
done.
(So, you use the same [or similar] algortithm that has been
employed by Spamcop and Co. for some time now to validate the
header information and then, when you find a forged sender, you
clog the internet with useless bouncebacks to machines that are
likely not owned by the spammer you want to harm.)
___________________________

Looks to me like a) nothing new from a technology perspective,
b)
something we would NOT want to see done vis-a-vis rampant
bouncebacks, and c) something that does nothing like SpamCop
does
to inform ISPs and other interested parties of the spam that is
occuring.  In short, IMHO, this is a bad idea.

Cheers

Bart

If you would like an alternative, you can sign up for a beta

an

address which you will be given. Everything else is taken care
of.

The
signup is free and easy but limited. Click the Personal tab...

Has anyone got a automated spamcop reporting script?


Thanks in advance if you can send in .txt format
preferably offlist.

I hit the send before I could explain what I wanted to do...
I have a spamcop account - and I managed to get the spamcop
Url with the reportID to a file using fetchmail + grep
Combination.

But there is some thing I cannot get working with the
Spamcop spam submission form used to complete the spam
Reporting. Has anyone made something like this before ?
