# Beta Zones

> 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.

# **Introduction**

We aim to offer the most advanced and precise threat intelligence possible through Guardian Mail.

We strongly advocate the “Release Early, Release Often” approach, which gives our customers early access to our work. This allows them to test and provide feedback on our progress if they so desire.

We provide access to beta lists as separate [DNS](https://abusix.com/glossary/domain-name-system/) zones and through rsync. For rsync customers, access is granted in the “beta-lists” module, which can be enabled in the getabusix.conf file.

> ❗**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.

# **Zones**

***

## **btc-wallets (Bit Coin Wallets)**

**Status:**

Beta

**Type:**

SHA-1 hash

[******Cloud DNS namespace:******](https://abusix.com/glossary/domain-name-system/)

\<APIKEY>.[btc-wallets.mail-beta.abusix.zone](http://btc-wallets.mail-beta.abusix.zone).

**Rsync File:**

beta-lists/[btc-wallets.zone](http://btc-wallets.zone)

**Return Codes:**

127.0.4.1

**Test Points:**

127.0.0.2

**Listing Duration:**

Approximately 5.2 days after last seen

**Description**

We developed this zone to list BTC Wallet addresses seen in the message body of [spam](https://abusix.com/glossary/spam/) sent to traps.

Because it is impossible to represent a BTC Wallet address in a [DNS](https://abusix.com/glossary/domain-name-system/) query, they are SHA-1 hashed, and the hash value is used for lookup instead of the URL.

For example:

```
SHA-1(15GWKdT8e1o6GcDTZMQZRiZng2Q6dLX8Aw) ->
e108c5b4bde457dcc35f009d05a21fa383eda04c
```

> 💡 **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

## **attachhash (Attachments)**

**Status:**

Beta

**Type:**

SHA-1 hash

[******Cloud DNS namespace:******](https://abusix.com/glossary/domain-name-system/)

\<APIKEY>.[attachhash.mail-beta.abusix.zone](http://attachhash.mail-beta.abusix.zone).

**Rsync File:**

beta-lists/[attachhash.zone](http://attachhash.zone)

**Return Codes:**

127.0.5.1

**Test Points:**

127.0.0.2, 127.0.5.1, 3395856ce81f2b7382dee72602f798b642f14140 (EICAR with trailing newline), cf8bd9dfddff007f75adf4c2be48005cea317c62 (EICAR)

**Listing Duration:**

Approximately 5.2 days after last seen

**Description**

This experimental zone lists the SHA-1 hashes of any attachments our trap network sees.

> 💡 **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.

## **forged**

**Status:**

Beta

**Type:**

[IPv4](https://abusix.com/glossary/internet-protocol-version-4/), [IPv6](https://abusix.com/glossary/internet-protocol-version-6/)

[******Cloud DNS namespace:******](https://abusix.com/glossary/domain-name-system/)

N/A, not currently published

**Rsync File:**

beta-lists/[forged.zone](http://forged.zone)

**Return Codes:**

127.0.0.5

**Test Points:**

127.0.0.2, 127.0.0.5

**Listing Duration:**

Approximately 5.2 days after last seen

**Description**

This zone lists [IP](https://abusix.com/glossary/internet-protocol-address/) addresses we have observed either forging mail from our trap domains or where we see traffic from [IP](https://abusix.com/glossary/internet-protocol-address/) addresses sending mail from domains that return [SPF](https://abusix.com/glossary/sender-policy-framework/) Fail results.

> ❗**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.

## **backscatter**

**Status:**

Beta

**Type:**

[IPv4](https://abusix.com/glossary/internet-protocol-version-4/), [IPv6](https://abusix.com/glossary/internet-protocol-version-6/)

[******Cloud DNS namespace:******](https://abusix.com/glossary/domain-name-system/)

N/A, not currently published

**Rsync File:**

beta-lists/[backscatter.zone](http://backscatter.zone)

**Return Codes:**

127.0.0.6

**Test Points:**

127.0.0.2, 127.0.0.6, ::FFFF:7F00:2, ::FFFF:7F00:6

**Listing Duration:**

Approximately 5.2 days after last seen

**Description**

This zone lists [IP](https://abusix.com/glossary/internet-protocol-address/) addresses that have sent bounce messages to our traps. Our trap domains are never used to send an email, so any bounce messages we receive are because someone else forged our domain, so any host sending us bounce messages is because they incorrectly accepted one of these messages and are therefore sending us “[backscatter](https://en.wikipedia.org/wiki/Backscatter_\(email\)).”

[Backscatter](https://abusix.com/glossary/backscatter/) can be a big problem if a domain is forged and used for a large [spam](https://abusix.com/glossary/spam/) run, and this zone can help mitigate the fallout from this.

Unlike other blacklists, our only inclusion criteria are [DSN](https://abusix.com/glossary/delivery-service-notification/)/MDN messages; we do not consider “Sender Verification” or “Sender Callouts” as [backscatter](https://abusix.com/glossary/backscatter/).

> ❗**Warning** This zone should **NEVER** be used as a regular [DNSBL](https://abusix.com/glossary/domain-name-system-blocklist/); it should only ever be applied to messages that have a null Return-Path (e.g., MAIL FROM:\<>)

## **emailbl**

**Status:**
