I'm trying to set up what microsoft calls a "smarthost". Ive got a running, established iRedMail server, that is currently acting as a backup MX for this domain for which i would like to set up "smarthost" services. I know that i need to add the ip address of the exchange server to the "mynetworks" section of main.cf, and i know how to configure my exchange server to use it. I dont know the following;
1. How do i set up authentication on the iRedMail system ?
2. How do i make sure that when the iRedMail system sends the mail for the exchange system, it leaves the original sender intact ?
I appreciate all of your help and guidance sir
