sucees Transmit status in Xbee API format indicates correct delivery of packet at the destination node.?

What is the maximum baud rate supported by the Xbee Digimesh module? I need to send 10000 packets with payload size of 67 between two Xbee digimesh module continously. When i check the transmit status it was success for all the packets. But most of the packets were not receiving at the destination node. The baud rate of xbee digimesh module was set to 57600.

You have not indicated which XBee modules you are using. That is something that is very important to answser this with. However, I would suggest checking the product manual for that speciifc module. You should find a Throughput section that will have the streaming limit listed.
