How to handle exception while sending 500 messages for an interval of 10 sec

[LunarSatellite]

We are sending 500 messages for an interval of 10 sec but while observing the sending report those messages which are not sent from our end has no information of submit_sm and destination address due to which we are not being able to handle the exception of such failure message since sequence numbers are duplicate due which it became more complicated. Please suggest us how we handle the case while sending huge message at a time. There will be only message called error sending message 20.
