      #                                        - message_time\__gte: gte stands for greater than or equal. The format expected is YYYY-MM-DD HH:MM[:ss[.uuuuuu]]. Eg:- To get all messages that were sent/received after or exactly at 2012-03-21 11:47[:30], use message_time\__gte=2012-03-21 11:47[:30]

      # @option options [String] :message_state Status value of the message, is one of "queued", "sent", "failed", "delivered", "undelivered" or "rejected"
      # @option options [Int] :limit Used to display the number of results per page. The maximum number of results that can be fetched is 20.
      # @option options [Int] :offset Denotes the number of value items by which the results should be offset. Eg:- If the result contains a 1000 values and limit is set to 10 and offset is set to 705, then values 706 through 715 are displayed in the results. This parameter is also used for pagination of the results.
