I have read several posts about installing zimbra on ubuntu but almost all are discussing scenarios where server is behind firewall or DMZ.
Now, i want to know, if i have DNS configured on my ISP servers do i still need to configure DNS on my server while it is not behind firewall?
I ask this because i'm facing DNS problem when installing Zimbra.
My server is accessible to the world directly with public ip address. I dont have LAN ip configured.
Thanx in advance.
