Find out more about our comparison tool.


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

To make this much easier, quicker, repeatable and transparent, we have created a comparison tool that you can use to get a indication of how Abusix Mail Intelligence compares to other lists that you currently use and can be run in a few hours or less and that requires no changes to your mail system.



The tool is supplied as a Linux binary and should be run on a machine inside your network that has access to the necessary DNS namespaces to be able to query Abusix Mail Intelligence and the list that 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 it's advantages and disadvantages:

- Easier to collect the necessary data. - Very quick 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 setup. - Does not provide in-depth analysis, only provides IP addresses missed by Abusix.
