What is Abusix Mail Intelligence?


Abusix Mail Intelligence™ is a suite of curated DNSRBLs designed to protect inbound and outbound mail servers.

Since our goal is to provide the most accurate, comprehensive, and innovative real-time threat intelligence data, we service our service from our own Abusix Intelligence™, an extensive network of spam traps and honeypots across the globe. Abusix Intelligence provides our customers and ourselves with real-time, actionable threat intelligence data that can be used to prevent spam, phishing, malware, and any other types of abuse.

It has never been our intent to be the “internet police”; as we will never do punitive or escalation listings – we will always be evidence-driven (e.g., listing only what is hitting our traps or where we have good evidence that spam is being emitted to our customers).


Abusix Mail Intelligence™ is provided as RFC-5782 compliant DNS lists that any SMTP server can query, or anti-spam software, appliance, or software that implements DNSBL, RHSBL, and URIBL lookups can apply.

What is your recommended configuration?

During SMTP Transaction

We recommend using Abusix Mail Intelligence™ on SMTP servers on the edge of your network (e.g., your MX hosts) to hard reject mail during the SMTP transaction using our "combined" IP dataset and “dblack” domain dataset returning the TXT record we provide, when we return a positive result.

During Content Analysis

If a message is accepted, we then suggest that you run further content inspection (like SpamAssassin or rspamd) and check Abusix Mail Intelligence™ against each received header hop and check the body of the message for URLs containing blacklisted domains, short URLs and drive URLs (using our shorthash and drivehash lists).

see Production Zones for more information about the lists in our suite
