About MX string
Sorry for bad English
How I can solve problem with installation on other server instead of main mail server?
22.214.171.124 external ip mail.foo.ru ( there is work server )
192.168.0.1 internal ip mail.foo.ru
192.168.0.2 on this server will be zimba ( testing)
I have broken a head while tried to adjust DNS, but still got error
Please enter the logical hostname for this host [foo.ru] raven.foo.ru
No results returned for A lookup of raven.foo.ru
DNS ERROR resolving raven.foo.ru
It is suggested that the hostname be resolveable via DNS
You either need to setup DNS for that host or create a local BIND service to publish a local DNS record for the host.
