How to set up relay host in dmz via public if

Hi all , 

 

we have a Cluster ESA C300V and a solution with 2 interfaces. One Public ( is in DMZ Range)  and one internal. As i can see for the interfaces public there is HAT and RAT configured for internal only HAT. ok..everything works fine. 

 

Now the question is how its possible to set up a standalone mailserver with a different external domain (which only must send not receive mails) and also stands in the DMZ. As i Created a Sender Group with this IP and a MF Policy with Relay i thought it should work via the Public if.

But i can see in the mail_logs for testmail there was the information "rejected by RAT" ..

 

Is it the wrong way to impement this or where could be my issue??


Thanks a lot 


Regards
