   @duhenglucky Thanks for your invitation, I'd like to polish this mechanism and how can i join it?
   Reply to the second question:In fact, when users happen the SYSTEM_BUSY or other exceptions which are not in the retry list,users always resend the message themselves immediately in order to prevent sending failure.It will still increase the load of the server.Maybe rocketmq should provide a self-later-resend mechanism when SYSTEM_BUSY or other exception happens.
