Number of retries for a failed async message

Hi experts,

I understand that I can set the following parameters in NWA for number of retries of failed message

"xiadapter.inbound.numberRetries.default" and "xiadapter.inbound.retryInterval.default"

But say if my receiver system is down and number of retries is 3 then the message will be canceled after retrying 3 times ??

What if the receiver systems is UP after that....should not PI keep that message in Queue and resend the message when the system is UP.

At least that is what guaranteed dellvery means
