After setting up mailinabox successfully, I attempted to move the server to an nfs mount so I would have more disk space for emails than what I allocated for the vm. As suggested by https://discourse.mailinabox.email/t/mailboxes-storage-location-and-quota/3704 I copied the data at
/home/user-data to the nfs drive, made a symbolic link, then restarted the nginx service just to make sure things were still working. Now I get an http 500 “Something went wrong, sorry” error when I go to System → Status Checks.
When I run the status_checks.py script manually, I get the following output
System ====== ✓ All system services are running. ✓ SSH disallows password-based login. ✓ System software is up to date. ? You are running version Mail-in-a-Box v63.

The warning and two status failures are expected, but the Python error is not. After seeing this, I assumed running mailinabox setup would generate this “K_domain” file but it doesn’t, instead I get a similar error at the end of the output:

At this point I am able to login to /admin and /mail, however Status Check still fails.
How can I regenerate this file so status check can work again? I’m not sure how I lost it in the first place or if it was ever created since I never configured dnssec.
