@Robb is trying to create an alternative for ICT structure.
He’s considering to put his mailserver into VPS and connect it with a remote userbase (via VPN) for consolidate the user accounts db into one place.
Therefore it’s my example:
- install a server with user account database
- install a mailserver which fetches the user account database from this authentication server
- connect them via VPN connection AND public internet
What happens if the mailserver loose for a consistent and undefined amount of time the connection to the users db?
For consistent i’m meaning starting from 48 hrs to 5-10 days.
