We are running a Zimbra server on 16.04. today we changed the ip address and location of the server. Most issues have been resolved other than name resolution. The server is listening on 127.0.0.1 but unable to resolve. If we change resolv.conf to 188.8.131.52 we can resolve, However, resolve.conf will get overwritten of course. interfaces is set up correctly with dns-nameservers 184.108.40.206 - not really sure why it is listening on 127.0.0.1?
Trying to understand why resolv.conf is reverting to 127.0.0.1 when dns-nameservers is correctly set? Note, we are not running dnsmasq. Also this is a basic virtual machine install (I dont believe Network Manager is installed)
Appologies if this is a simple question!
