I am trying to setup authenticated relaying for my own domain. here is what i am getting : CLient does not have permissions to to send as this sender error 5.7.1 (my own account)
I can allow unauthenticated relaying but keep getting the above error. this docuemnt says exchange supports relaying out of the box:
On the Receive Connector: (Permissions) i have exchange users, (Authentiation) Basic Auth is selected.
this has not been my experience.
What am i missing here? this isnt that hard right?
