Noticed that my DNS checks all simply complain that the local host doesn’t answer DNS anymore (no response from 127.0.0.1).
I do run my own DNS servers for my domain, but this is just the mail in a box server testing itself.
I don’t see any special “mail-in-a-box” dns settings either? the mailinabox command completes without errors.
What looks wrong with any of this?
