Overview

Abusix Mail Intelligence™ is a suite of curated DNSRBLs designed to protect inbound and outbound mail servers. We aim to provide the most accurate, comprehensive, and innovative real-time threat intelligence data. To achieve this, we have created 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 intention to act as the "internet police." We will never do punitive or escalation listings. Instead, we will always be evidence-driven, 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.

We recommend using Abusix Mail Intelligence™ on SMTP servers at the edge of your network (e.g. your MX hosts) to reject mail during the SMTP transaction. Our "combined" IP dataset and "dblack" domain dataset can achieve this. If we return a positive result, you can reject the email using the TXT record provided.

If a message is accepted, we suggest running further content inspection, such as SpamAssassin or rspamd. Additionally, check Abusix Mail Intelligence™ against each received header hop, and examine the message body for URLs containing blacklisted domains, short URLs, and drive URLs using our shorthash and drivehash lists.
