What we use in my office, depends on the type of servers:
- For virtual server (we made a golden template of it) we use Debian 12
- For virtualization host/ganeti cluster we use Debian 11
- For NAS, we use OpenMediaVault (based on Debian)
I slitter around.

I’m an admin of a self hosted iRedMail (with iRedAdmin Pro).
My advice is: Don’t.
Getting an email server running is easy. Managing them is not.
There are some good advice here. Use commercial service with personal domain.
I would like to default to debian 12 if I have to start fresh.
The Ganeti Cluster was installed on Debian 10 then when 11 launched, I upgraded it. It’s a 10 nodes cluster and I just don’t have time to upgrade it yet. The last update to 11 took me a week to troubleshoot.
