Since having a Mac mini at I currently have the luxury position of having two Mac mini’s connected to the internet. This gives me the ability to try new configurations for the DIYMacServer setup.

The first thing I tried, now I’ve got everything migrated, was getting my home server to work as a backup MX server. I found out that it was pretty straightforward and adding one line to the main configuration made it work.

I’ve added it to the documentation set, so if you have the same luxury as I have and have more than one server connected you could use the this as well. Read how to do it here: Configuring a backup (relay) MX server.
