Listing on Backscatterer blacklist indicates that your server is issuing "backscatter" in the form of Non-Delivery Reports (bounces) to external users, or misdirected autoresponders and sender callouts. Much of this is a function of how your server configuration is set to handle emails directed to users that do not exist on the server and can cause many problems, especially if you are hit with a directory-harvesting attack. Simply requesting delisting and paying their fee will do nothing to help you correct the problem and will give you no guarantee that you won't get blacklisted again.

Backscatterer 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.

Backscatterer 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.

Backscatterer Accepts Payments Or Donations

This blacklist does support a manual request to remove, delist, or expedite your IP Address from their database upon Payment or Donation of fees to their organization. Please note the following; 1) MxToolBox does not in any way advocate the paying of removal from any blacklists. 2) Removal requests that are submitted without addressing the core problem will likely result in your IP Address being relisted in the database which can cause subsequent problems and extended listing periods without release.
