First post, bear with me if it is a repeat...
Does anyone have a good tutorial or idea for creating a backup MX on a VPS? I have a mail server at home (simply for testing/learning) and I want to use one or both of my VPSs to hold mail in the event my home server is unreachable. I know there are commercial services for this, but I'd like a DIY solution.
My VPSs are running Debian 6.
Any ideas?
Thanks!
