# cPanel API 2 Functions - Email::listfilterbackups

Warning:

The cPanel API 2 system is deprecated. We **strongly** recommend that you use [UAPI](/cpanel/introduction) instead of cPanel API 2.

## Description

This function lists domains with domain-level filters. For more information about Exim filters, read Exim's documentation.

Warning:

We **strongly** recommend that you use the following [UAPI](/cpanel/introduction/) function instead of this function:

- ` Email::list_filters_backups ` — This function lists all of the cPanel account's domains that use domain-level filters.

Important:
br
When you disable the [*Receive Mail* role](https://docs.cpanel.net/knowledge-base/general-systems-administration/how-to-use-server-profiles/#roles), the system **disables** this function.

cPanel Tag System (deprecated)

div
Warnings:
br
- cPanel tags are **deprecated**. We **strongly** recommend that you **only** use the [LiveAPI](/guides/guide-to-the-liveapi-system) system to call the cPanel APIs. Examples are **only** present in order to help developers move from the old cPanel tag system to our [LiveAPI](/guides/guide-to-the-liveapi-system).
- cPanel API 2 calls that use cPanel tags vary in code syntax and in their output.
- For more information, read our [Deprecated cPanel Tag Usage](/cpanel-api-2/cpanel-api-2-deprecate-cpanel-tag-usage/) documentation.
