I found a python DNS test too in the mailinabox log folder: It asks that I rerun mailinabox, which I have done a few times (with reboots). This is when the /etc/resolv.conf points at 120.0.0.1 at each reboot, not using my internal DNS server. Wouldn’t the mailinthebox install script have complete control over building this out? (I have made no custom entries)
