Open Relay Server Postfix with 2nd Server for HA


Hello this is my second thread about postfix, because i never got a straight answer. I need to create an OPEN relay server, without any authentication or security. Anywhere i look on google there's examples for closed and using your smtp server relay, which i don't understand.
i hadn't have found even one good example how to create this open relay that doesn't stores mail just forwards it to its destinations.
I have reversed dns from my isp already, could someone help me out?
Also need to create second server in case if the primary relay sever fails the second relay server kicks in, is this possible?
I know Open relay is not a good idea with no tls ssl etc, but this is the requirement of my project, which is pointless in my eyes but has to be done.
Using ubuntu 16.04 with postfix 2.5.3
