"""
Send out the email using the details from the ``message`` argument.
message
The information on the message to send. This argument must be
sent as dictionary with at fields as specified in the Mandrill API
documentation.
asynchronous: ``False``
Enable a background sending mode that is optimized for bulk sending.
In asynchronous mode, messages/send will immediately return a status of
"queued" for every recipient. To handle rejections when sending in asynchronous
mode, set up a webhook for the 'reject' event. Defaults to false for
messages with no more than 10 recipients; messages with more than 10
recipients are always sent asynchronously, regardless of the value of
asynchronous.
ip_pool
The name of the dedicated ip pool that should be used to send the
message. If you do not have any dedicated IPs, this parameter has no
effect. If you specify a pool that does not exist, your default pool
will be used instead.
send_at
When this message should be sent as a UTC timestamp in
``YYYY-MM-DD HH:MM:SS`` format. If you specify a time in the past,
the message will be sent immediately. An additional fee applies for
scheduled email, and this feature is only available to accounts with a
positive balance.
.. note::
Fur further details please consult the `API documentation <https://mandrillapp.com/api/docs/messages.dart.html>`_.
CLI Example:
.. code-block:: bash
salt '*' mandrill.send message="{'subject': 'Hi', 'from_email': 'test@example.com', 'to': [{'email': 'recv@example.com', 'type': 'to'}]}"
