A preview set of experimental DNS zones and threat data from Guardian Mail, offering early access to emerging anti-abuse signals for testing, feedback, and non-production scoring.
❗Important Note Beta lists may be incomplete, inaccurate, or poorly tested, and may be removed at any time. Therefore, it is strongly advised not to use these beta lists in production or to reject mail; they should only be used for reporting or for weak scoring.
💡 Info As this is an entirely new type of anti-spam check, it will require support to be added to your chosen mail platform. **Rspamd **Please look at our set-up instructions for rspamd, which contains the necessary code to do these lookups. See Getting Started

❗Important Note This list is not currently well-tested and is very much a work in progress, so it is not recommended to use this for anything other than scoring or testing.
❗Warning This zone should NEVER be used as a regular DNSBL; it should only ever be applied to messages that have a null Return-Path (e.g., MAIL FROM:<>)
