More Information About Sem Backscatter
If you are on the Spam Eating Monkey Blacklist, there could be any number of issues that need to be addressed in your network: virus-generated spam, dynamic IP Addresses previously used by spammers or bulk mail sending that does not comply with the CAN-SPAM Act.
Sem Backscatter Reports Sources Of Backscatter
Backscatter Blacklists are specifically looking at a type of traffic from an email server IP Address related to a Non-Delivery Report/Receipt (NDR), also called a bounce-back or bounce message. Backscatter (also known as outscatter, misdirected bounces, blowback or collateral spam) is the incorrect automated bounce messages sent by mail servers, typically as a side effect of incoming spam from a Denial of Service (DoS) or Directory-Harvesting attack on a mail server. In this kind of attack, the attacker spoofs (or forges) the source address in IP packets sent to the victim. In general, the victim machine cannot distinguish between the spoofed packets and legitimate packets, so the victim responds to the spoofed packets as it normally would.
Sem Backscatter Automatically Delists Entries
This blacklist does not offer any form of manual request to delist. Your IP Address will either automatically expire from listing after a given timeframe, or after time expires from the last receipt of spam into their spamtraps from your IP Address.
