Hey Community,
I´ve got a probleme which I don´t know how to fix, maybe some of u can help me!
I´ve created a MTA on my Sophos XG 18 which receive and send Mails for my Exchange 2016.
Now I have checked my mail flow and to my suprise mxtoolbox said it could be an open relay and yes, it is.
Here is my configuration, maybe I´ve overlooked something.
Where is my probleme?!
Many thanks
