Some time ago I set up Mail In a Box using Glue Nameservers for my domain, example.com.
At the time of setup, I chose to create (and use) the glue nameservers
ns2.box.example.com however, now I would like to change it to
I know what I have to do on the registrar side, but I am clueless what to do on Mail in a Box’s end. I can see that I have my zonefiles on /etc/nsd/zones and theoretically I could just edit them, but since they’re DNSSEC-signed, I am afraid to end up “bricking” it.
Has anyone ever done this?
