who can tell  me the real reason 202.108.3.173/174/176/177 blocked

35789[/snapback]

I checked the blocklist and only 202.108.3.176 and 202.108.3.177 seem to be listed currently.

For *.176 the report is:

202.108.3.176 listed in bl.spamcop.net (127.0.0.2)

If there are no reports of ongoing objectionable email from this system it will be delisted automatically in approximately 15 hours.

Causes of listing

    * System has sent mail to SpamCop spam traps in the past week (spam traps are secret, no reports or evidence are provided by SpamCop)

Additional potential problems
(these factors do not directly result in spamcop listing)

    * DNS error: 202.108.3.176 is mail3-176.sinamail.sina.com but mail3-176.sinamail.sina.com has no DNS information

Because of the above problems, express-delisting is not available

For 202.108.3.177 there are a number of messages that clearly appear to be UCE. Reports for these messages were sent to abuse[at]sina.com

This IP is also listed for sending to spam traps plus some users have also reported the IP. Should de-list in 22 hours.

You can check your listing at http://www.spamcop.net/w3m?action=blcheck - just pop the IP address in the form.

You may well be a large mailhost but China is a large source of UCE and your system appears to be misused.

If you deal with those accounts, then you should not have problems with the SpamCop blocklist. The SpamCop Blocklist does not list IP addresses unless spam is reported from that IP address.

Dealing with spammers means not letting them use the internet. If it is a customer who has let his computer become infected with a trojan, then you must also stop his internet access until he gets his computer cleaned. You can help him get rid of the trojan and teach him how to protect his computer.

You can also educate your customers about how to use the internet to send bulk email. Best Practices Web site has lots of information.

There are also links here just for administrators: Assistance

There are people here who will help you understand if you ask specific questions.

Simple:

Lexical Contradiction: Spammers will redefine any term in order to disguise their abuse of Internet resources.

Sharp's Corollary: Spammers attempt to re-define "spamming" as that which they do not do.

And they always answer the issue of least relevance. The fact that UCE is reaching spam-traps seems to me far more conclusive than a debate about whether the rDNS is correctly set up B)

spam Traps do not send reports. Email going to spam traps has more influence on listing than reports from users. You receive reports from users who want you to take action. spam Traps do not send reports because only spammers could know the email address.

You must stop your customers from sending emails to people who do not want them. There is no other way to avoid listing.

202.108.3.217 is always blocked ,how can we do ?the reason is :

perhaps many people send spam to us , so we i have to bounce to other , not our fault ,what can we do ?

Yet another "new" Topic asking yet the same question ..... different IP address, yet the same issues are involved .. so "new" Topic Merged into (just one of the many) an existing Topic by the same poster.

202.108.3.217 listed in bl.spamcop.net (127.0.0.2)

If there are no reports of ongoing objectionable email from this system it will be delisted automatically in approximately 21 hours.

Causes of listing

System has sent mail to SpamCop spam traps in the past week (spam traps are secret, no reports or evidence are provided by SpamCop)

It appears this listing is caused by misdirected bounces. We have a FAQ which covers this topic: Why auto-responses are bad (Misdirected bounces). Please read this FAQ and heed the advice contained in it.

Additional potential problems

(these factors do not directly result in spamcop listing)

DNS error: 202.108.3.217 is mail3-217.sinamail.sina.com.cn but mail3-217.sinamail.sina.com.cn has no DNS information

You do not have to bounce spam. There are two kinds of bounces: the first one is 'bounced' by the server with a 5** message. The second one is received by the server and then sent to the return path or From. It is the second kind that is causing you to be listed. The reason is that spammers forge the return path or From. The 'bounces' then go to people who didn't send them.

There are different kinds of blocklists to 'reject' email at the server (the first way). Or if you want to accept all email, then the email that is not yours, you need to delete.

If you read the FAQ and need help with understanding it, ask here. Someone will help you to understand.

You may want to look at the following links; you have quite a extensive history of being listed for sending mail to spamtraps (most likely bounces)

Only one of the addresses shows any history of reports of spam being filed by users.

The reason is SpamCop does not send out reports on mail that hits spamtraps.

All but one of the IP addresses you listed in your other topic were only on the SpamCop BL due to SpamTrap hits.

Edit: note: reference to "other topic" is no longer valid as the original topic was mergered into this one.
