This function retrieves the domain's default address and its rules.

 The cPanel account's default (catchall) address handles unroutable mail that the account's domains receive.


We strongly recommend that you use the following UAPI function instead of this function:

  • Email::list_default_address

    Error rendering macro 'excerpt-include'

    No link could be created for 'UAPI Functions - Email::list_default_address'.




 For more information, read our Calls from the WHM API documentation.

 LiveAPI PHP Class
$cpanel = new CPANEL(); // Connect to cPanel - only do this once.
// Check's default address rules.
$check_default_address_rules = $cpanel->api2(
    'Email', 'listdefaultaddresses', 
        'domain'          => '',

    'Email', 'listdefaultaddresses',
        'domain'          => '',

 cPanel Tag System (deprecated)


  • In cPanel & WHM version 11.30 and later, cPanel tags are deprecated. We strongly recommend that you only use the LiveAPI 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.
  • 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 documentation.

 Command Line
