Comparison Tool Overview

Find out more about our comparison tool.


Testing a DNS blocklist to see how it might perform on your production mail stream can be difficult and time-consuming, often taking weeks and requiring considerable resources.

To make comparisons much easier, quicker, repeatable, and transparent, we have created a “Comparison Tool” that you can use to indicate how Abusix Mail Intelligence compares to other lists you currently use. The tool will allow you to run an evaluation in a few hours or less, requiring no changes to your mail system.


The “Comparison Tool” is run as a Linux or mac binary.

The tool should be run on a machine inside your network with access to the necessary DNS namespaces to query Abusix Mail Intelligence and the list you wish to compare it against.

It can only be used to compare Abusix Mail Intelligence with one other list at a time and only supports IPv4 and IPv6 lists; it does not support domain or hash lookups.

The tool has two modes, logfile or real-time/streaming.  Each mode has its advantages and disadvantages:

- Easier to collect the necessary data. - Rapid results. - In-depth analysis provided by CSV output.
- Should only be used on data that is < 2 days old because each list will have different policies for listing expiry. - Does not reflect how quickly a list reacts to spam, e.g., which listed the IP first.
- Needs real-time log data. - Can be run for as long as you like. - Identical to running both lists in production, so a perfect comparison.
- Can be more complicated to set up. - Does not provide in-depth the analysis only provides IP addresses missed by Abusix.
