I am struggling a little with setting up relaying for separate MTAs and would like any advice / documentation.
I have a seperate mailstore and mta. I would like to relay all mail out of the MTA and turn off the MTA on the mailstore.
How do I configure the mailstore to relay mail out via the MTA, and how do I configure the mta to relay mail for that mailstore?
I am not finding a lot of documentation on how to do this.
