To view registered handlers, run the following command:

# ./mail_handlers_control --list
    [ --mailname=<mailname> | --global ]
    [ --extent ]

The --list command has optional parameters:

• The extent parameter allows viewing additional information about handlers - the context and the full path to the executable file of the handler.
• The global parameter allows viewing only handlers of the global type. The mailname parameter shows the handlers registered for the specified domain or email address.
