FAQs
A blocklist (previously referred to as a blacklist) is a list of “items” that are considered as unsafe and therefore are denied access. A blocklist might consist of:
IP Addresses
Domain Names
Email Addresses
Short URLs
Drive URLs
Bitcoin Wallet Addresses
Attachment Hashes…
It is used to prevent the reception of spam, viruses, phishing, malware, and other email-borne threats.
Blocklists are used in various areas within security architecture, like; firewalls, DNS servers, directory servers, web proxies, authentication, and API gateways. While our blocklists are only designed for email servers.
Generally said, anyone running their own mail server can benefit from using a blocklist.

Generally said, anyone who does not run their own mail system can’t use a blocklist.
It’s also not possible for companies that outsourced their mail scanning to a 3rd party cloud-based shared platform (Microsoft 365, Google Workspace, Mimecast, Proofpoint, etc.)
It’s difficult to apply blocklists for single tenants on a shared system, they have to be used for all tenants.
There are three main use cases for our blocklists:
– Block inbound SMTP traffic
– Prevent bad email from leaving your network for outbound SMTP traffic
– Assist you in catching compromised accounts and services within your own network
We use four main methods that can get you listed on one of our blocklists:
– Spam traps
– Heuristics
– Honeypots
– Policy
Generally said: Yes, the more filter, the better! But those vendors should be accurate, reliable, and well-supported. We wrote a blog post on this topic here. If you consider switching vendors but are still unsure, we have a comparison tool that lets you compare the effectiveness of our different blocklists (RBL/DNSBL).
Yes, if you are unsure whether our blocklist work for you, here’s help! We build a blocklist comparison tool, which lets you compare the efficiency with your current IP blocklist setting vs. our blocklist. There is no need to change your live environment. Sign up for a free trial and download the Linux script (Email Protection –> Get Started Section) and follow the documentation on how to set it up.
We provide more than 10 different blocklists, such as IP addresses, domain datasets, hashed datasets for short URLs, drive URLs, bitcoin wallet addresses, and email addresses.
Most of our customers use our combined list, which combines our IP, exploit and policy list.
For additional filtering, we provide datasets like newly observed domains or newly observed mail IPs.
If you want to prevent compromised accounts within your network from sending outbound spam, you might want to check out our AuthBL blocklist.

Generally – the answer is no. Neither service allows for the addition of 3rd party DNS reputation lists like our Abusix Mail Intelligence blocklists. But if you are running email gateways in front of either Google Workspace or Microsoft 365 with your domain MX records pointing to these instead, using Abusix Mail Intelligence blocklists as an additional spam filter is indeed possible.
The email gateways can then be configured to use Abusix Mail Intelligence blocklists to reject messages prior to sending them onwards to Google or Microsoft.

We only add entities to our welcome list in specific circumstances:
– There have been repeated listing issues.
– These have been sufficiently resolved and procedures have been put in place to prevent these from happening again.
– The IP address or domain name is shared amongst a lot of other customers.
– You can supply an SPF record that only contains SMTP server addresses.
Outbound spam can adversely affect your reputation, causing your own mail server to be blocked, which can affect all of your customers that are sending mail through your system. We have a specifically designed blocklist for your outbound traffic that will point out compromised accounts for you. Read more in our blog post here.
