Anti-Spam Alliance blacklist Service

Real-time mail blacklist service, as an effective service against the spread of spam, has been widely used abroad. Many nongovernmental or official anti-spam organizations have launched their real-time blacklist for users to choose from. Real-time blacklist is based on the analysis of artificial or machine to determine whether an IP address is a spam source, so that it blacklisted. The user's mail server can query the blacklist to decide whether to accept messages from that address. In determining whether it is a spam source, the majority is based on the number of spam sent to the address and the nature of the address spam (such as unsolicited malicious send, passive use of sending, etc.) to judge. Although an address may send a number of spam messages in addition to sending a large amount of junk e-mail, a compromise between rejecting very few normal messages and receiving a large amount of spam is to use a blacklist to protect the mail service from working properly. In addition, a message that rejects an address can quickly cause an administrator of that address to notice that the address is sending spam, which resolves the problem. A blacklist of addresses can cause mail servers that use the blacklist to not accept mail from that address, so we take a very cautious approach to blacklisted addresses and maintain blacklist maintenance in accordance with established procedures. The maintenance process can be described as follows: blacklist add: 1, received the user complaints, from the complaint email analysis of the source of spam; 2, to determine whether the address is open-relay, open-proxy, etc. due to improper configuration caused by the use of passive spamming; 3, if it is passive to send spam messages , we will contact the administrator of the address (if we can contact it), require its time limit to improve the security of its mail server; 4, if it is unsolicited spam, we will contact the administrator of the address (if can be contacted), ask it to stop its or their users to send spam; 5, If the status of sending spam to this address has not improved within a certain period of time, we will include our blacklist in our address, thereby protecting users who use our blacklist from spam from that address. Blacklist disengagement: 1, if an address has been included in our blacklist, resulting in some mail can not be sent to the normal, we may be made out of the blacklist; 2. After receiving the application, we will first check whether the address has stopped spamming or solved the problem of passive spamming; 3. If the confirmation stops, we will remove the address from our blacklist and take effect the next time the Blacklist is updated; 4. If there is still no evidence of a credible stop, we will continue to keep the address in our blacklist. A lot of foreign blacklist for domestic IP address some discrimination, such as often without careful judgment on some of the domestic address, or even a whole class C address are included in its blacklist, resulting in foreign customers can not accept from the domesticLetters. Our blacklist in maintenance will try to be rigorous and serious, to ensure that neither the real source of spam to let go, nor the innocent address into. Our blacklist is specifically for the domestic spam situation established, so more in line with the domestic situation, suitable for domestic mail server use. Therefore, our blacklist service is also called "China Junk Mail Blacklist"--CBL. At present, our blacklist service is completely free to open, the user only needs to register the application to use.
