What is DNSBL filtering?
It will also benefit you if you can grasp or understand the concept of DNSBL filtering as this is where the services of the Spamhaus organization, especially Zen Blacklist, mainly revolves. DNSBL advisory system plays the role of providing an opinion on whether or not an IP address abides or meets the Spamhaus’ regulating policy to be accepted to an email. To make a shorter description of the process of the DNSBL filtering:
- The flow begins by the sender sending a message to the receiver;
- The message will flow through the internet;
- The receiver will receive the message;
- Which will then ask the Spamhaus filters if the sender’s IP address meets its standard policy.
- Spamhaus will answer the question
- All messages rejected by the Spamhaus filters will then be directed to the Junk folder or Spam folder.
Zen Blacklist: Overview
Zen Blacklist is one of the Spamhaus listings. It is a DSBL (Domain Name System Block List), the other blocklist of the Spamhaus organization. Zen Blacklist’s components are a combination of various DSBL’s also such as SBL (Spamhaus Block List), XBL (Exploits Block List), and PBL (Policy Block List). The combination of its fellow DNSBLs made Zen a powerful blocklist making query faster and simpler. Since it is a combination of IP blocklist, Zen requires that it be the only Spamhaus DNSBL in your blocklist configuration. Using it together with other Spamhaus blacklists will only serve as a waste of your time as it will slow down your mail queue. Zen blacklist is a public-based blocklist of the Spamhaus. It is responsible for identifying and rejecting a majority percentage of the daily mail traffic. Even though all modern mail servers can use it, not everyone can access its services that easily. It is only free of charge for low volume non-commercial use. It is advisable to refer to the DNSBL’s usage terms to see if you qualify to use it for free before including it as your mail server’s spam filter. The use of Spamhaus services by corporations or institutions who have a considerable amount of email traffic on a daily basis is required to make a subscription to either the Data Feed Service or the Data Query Service.

Spamhaus ZEN – Now we know
