Hi there,
I have never had the need previously (so I am not aware of the proper way to do
it) to allow another server to relay mail without authentication (most modern
apps can do so), however now I do.
What is the proper way to get a toaster (external in a data center) to relay
mail for one
You should be able to turn off the no-relay option by using the TCP Rules
Using the REAL IP address of your Internal Server (that would be the
Internet IP, not the LAN IP), add the line:
/I.P.A.D/:allow,RELAYCLIENT=,SENDER_NOCHECK=1
near the TOP of your file at */etc/tcprules.d/tcp.smtp*
