Rspamd fuzzy feed and DNSBL usage policies

If you use Rspamd fuzzy feeds and/or Rspamd URLs/Emails black lists then you need to understand the existing limits and whether you are qualifying for the free usage terms.

We cover here both fuzzy storage feeds and DNS lists, specifically URLs and Emails black lists. In future that could be extended to other intelligence resources provided by rspamd.com.

Free usage policy

We provide infrastructure to collect spam messages data and algorithms to convert spam waves to a usable set of blocked fuzzy hashes, urls and emails. All these operations require both hardware and human resources. Hence, we define fair usage policies to use these services.

To qualify for free usage of the feeds you must satisfy the following conditions:

1. Your use of the feeds data is non-commercial

or

2. Your query volume is less than 500,000 queries per day

This service also includes rsync based access to URLs and Emails feeds so you can use your own rbldnsd to serve this data with no delays to your email scanners.
