[exim] Retry hard and soft bounces

Hi,

We are using Exim 4.72 on CentOS server. We would like to set up retry
option differently for soft bounces and hard bounces as below:

Soft bounces: 2 times every 2 hours and then no more re-try.
Hard bounces: No more try at all.

Is it possible to configure this in Exim?, Please advice.

Thanks.
