HI Admins of UCEProtect
I read thru your readme file about how we got one of mail servers
listed (202.91.163.31). I grepped through the maillog files and sure
enough found one record with the UCEPROTECT label. I am willing to pay
for the instant removal of our IP. As i dont have paypal or use
moneybookers, do you accept other forms of payment? (note, i have visa
card).
Secondly, while i was able to trace the record, i am not certain as to
which of our hosted domains (we are data center hosting facility) in
fact sent the erring piece of email. The IP belongs to a server that
is hosting several virtual server with about 90 hosted domains. We are
running Plesk with Horde on the domain, so the all the records from
all the domains are lumped into one big maillog file. Any assistance
would be appreciated. The maillog does not indicate a from: data you
see.
This is what i can see from our maillog:

Backscatter in response to a single person-to-person typoed message
isn't spam, even if one of the typoes is in the From address. I've
never seen any of that kind.
Backscatter in response to a spam run or other bulky thing is spam.
(So yes, I consider the ton of crap I get whenever I post to Bugtraq
as spam.)

Compliant with the security requirements perhaps, but in this particular
case, skirting very close (if not right over the edge) of non-compliance
with laws and regulations covering them.
Believe me, I don't think you want _these_ NDRs to blackhole. At least
if you're American.

I assume they have a policy against OOO crap.
They are probably smart enough to understand the tradeoffs. I'll
bet they would be happy if they could just turn off NDRs and
would accept the confusion when mail is lost without any notice
in the case of typos.

A day or two ago, I was speaking to a, er, "governmental agency"
(which I'll leave nameless) that was more than a bit "stuck".
Security policies imposed on them from the, er, "another governmental
agency" was such that it was impossible from a security perspective to
have the front end (required to be _outside_ of the DMZ) "know" what
the valid recipients were (either by file or realtime query), and that
was true even for the next mail server in the chain (DMZ).
They were already aware of the problems with blowback (which is indirectly
how they came to be speaking to me), were taking measures to try to reduce
it, and volunteered that they felt that the policy was being inappropriately
applied, but ... stuck they were.

So, Scott Richter should be called a "high volume timewaster and
desired content burier deployer"?
Doesn't have the same ring. ;-)

I would argue this by looking at it from the point of the recipient.
>From my point of view, I get a ton of substantially identical,
unrequested, undesired, and all around unwanted messages from servers
all over the planet.
Content isn't relevant. The only thing that matters is that I didn't
request it, it's not personal correspondence, and *I* didn't initiate
the transaction.
