blacklists, whitelist from China -- documentation?
totojepast
They have been established by an official Chinese authority and they
seem to be able to catch some spam. However, I have been unable to
find any official documentation (blacklisting policy, response codes
etc.) in English. Has anybody had any experience with them?
The blacklists:
- cbl.anti-spam.org.cn
- cblplus.anti-spam.org.cn
- cblless.anti-spam.org.cn
The whitelist:
cml.anti-spam.org.cn

I'm sure it's obvious but I would like to remind everyone, it's probably a
very bad idea to use a blocklist whose policy you don't know or understand.
Without a description in English, I have no idea who runs this blocklist,
what it's supposed to do, or if it's appropriate for me to use.
CBL is also arguably a bad choice for their blocklist name.

Perhaps the OP means 'testing' in the sense of "atttempting to determine
what it is they contain", rather than "seeing how it does against a live
mail stream"? The former would make sense. The latter, I'm forced to
agree with you is probably a terribly bad idea.

That'd be a good capsule description of WHY it'd be a terribly bad idea.
> CBL is also arguably a bad choice for their blocklist name.
Oh, I dunno. If it's a mirror of the CBL, that would seem to be
the obvious name for it. If it's just the "China Block List", that'd
still be descriptive, although I'd be willing to bet that the CBL team
behind cbl.abuseat.org will probably not appreciate the invariable
confusion and "please delist me!" requests that will no doubt ensue.

It's not as far as I can tell. We don't use/query those lists,
but, I've almost never seen a collision between it and the CBL on
www.dnsstuff.com
These are known as "CASA-<something>" (where "something" is "CBL",
"CBL+", "CBL-" and "CDL") on www.dnsstuff.com, with a link
to http://anti-spam.org.cn/. This page has a stylized "CASA" on it
plus "My CASA", but as it's all chinese, I haven't a clue what the
page actually says.
If there's someone here who can read chinese, it'd be interesting
to know the gist of what these lists are.

Real-time blacklist (RBL) -- CBL/CDL/CBL+/CBL-
Real-time DNS blacklist (RBL) consists of four key

Apart from China is going CBL- CBL+ mail service operators

The blacklist is not very convenient to use real-time

are able to receive mail users.

situation, please refer to the relevant information they

White list included verification inquiry -- CML
China mail service operators white list (CML) mainly as a
useful supplement to CBL/CBL+.
As part of the mail service operators to standardize the

CBL lead to the inclusion of IP addresses and CBL+ China.

It can be said that some of RBL servers abroad more than
CBL suited to the conditions of China.
The CBL will address the occurrence of spam addresses

CDL -- Dynamic Address table is the collection of statistics in
China (including Taiwan) dynamic allocation address.
According to Internet practices, which addresses the dynamic
allocation (including dial-up, ADSL/ISDN dials Dynamic Broadband
Access, etc.) is usually used to provide users with an Internet
access function The mail server is not as a direct function of
the collection and delivery of mail.
Moreover, with access to lower cost, more and more spam senders
into dynamic way to send spam addresses. This means not only
low-cost but also better to avoid blocking and tracing.
Therefore, we believe that it is a dynamic source mail addresses
of the judgment, it can effectively reduce the amount of spam.
Given the surfeit of domestic ISPs dynamic addresses, but when
the changes. We welcome anyone to the CDL us to provide more

Dynamic Access addresses of the users should be provided by

There is another page (about 2-3 pages long) of legal related
to the specific ones pointed out (above).
There also a page on configuring DNS servers for use
with a local blacklist.
There seems to be forum pages, with newsletter announcement
and whitepaper type of stuff.
There is also a page of sponsoring (or founding) companies?
{I'm sure I missed other stuff.}

I am having a similar problem. It's causing some major frustration
for folks at my domain who are attempting to e-mail other folks. Is
there a way to get off of their list? I think some of the more well-
known SPAM filters are using their service to block spam. I am not a
spammer.

That does not sound like testing,
it sounds like recipients rejecting your messages.
If the recipients are not willing to whitelist
your messages (or do something else to make certain
they get them), they they don't really want them.
If those recipient need / want / expect those messages,
they will find a way to get them.
> Is there a way to get off of their list?
Perhaps, are you certain you are listed in the
specific DNSbls of anti-spam.org.cn ?
or some other of the 700+ public DNSbls?

I doubt it, unless "well-known SPAM filters"
with the localization of China & nearby.

Not many say they are Spammers,
certainly not most Spammers.

I don't think very many people will run afoul of the DNSBLs listed
above, except for email sent to China. Given that there's no
formal translations of their web pages, I wouldn't expect
them to be very widely used outside of China. I would not, for example,
expect many "well known spam filters" that are used in, say, Europe
or North America to use them.
You're probably thinking of cbl.abuseat.org. Which is completely
different (see the rest of this thread). Go to the cbl.abuseat.org
web site and check out their lookup/removal pages.
