Edge IP blocklist feedback customisation

Hello together,

On an Edge server 2013 we use some RBL blocklists. If a sending mail server is listed on a RBL it get an NDR 550 5.7.1 Recipient not authorized, your IP has been found on a block list".

We found this default text as not such useful in some cases and would like to customize it, e.g. to contain the RBL which show the IP as blocked. 

Is there a way to customize the NDR?

Thanks a lot
Max Kaiser
