Implement Zone-Checking, f.e. "nast"
For new domains a tool to check-up zones may be useful to keep an eye on them if there is something wrong in the configuration (DNS).
The DeNIC does provide a script that did good work for me on checking my Zones against my configured Nameservers.
They also provide "Nast" for Download. This or any compareable solution may be a good feature to implement.
