module: webfaction_mailbox
short_description: Add or remove mailboxes on Webfaction
description:
    - Add or remove mailboxes on a Webfaction account. Further documentation at http://github.com/quentinsf/ansible-webfaction.
author: Quentin Stafford-Fraser
version_added: "2.0"
notes:
    - "You can run playbooks that use this on a local machine, or on a Webfaction host, or elsewhere, since the scripts use the remote webfaction API - the location is not important. However, running them on multiple hosts I(simultaneously) is best avoided. If you don't specify I(localhost) as your host, you may want to add C(serial: 1) to the plays."
    - See `the webfaction API <http://docs.webfaction.com/xmlrpc-api/>`_ for more info.
