Dear All,
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.
Regards,
Mnzava
You can install Zimbra anywhere you like, completely open to the internet, behind a NAT router, behind a firewall - the (security) choice is yours.
Dear Bill,
hank you very much for your reply.
Now coming to my problem. When installing zimbra i got this error.
Then i tried to accept changing domain name.Code:DNS ERROR resolving MX for mail.ardhi.go.tz
It is suggested that the domain name have an MX record configured in DNS
Change domain name? [Yes]
Create domain: [mail.ardhi.go.tz] ardhi.go.tz
MX: mail.ardhi.go.tz (172.16.16.2)
Interface: 172.16.16.2
Interface: 127.0.0.1
done.
Then installation completed without any error.
Now when i try to send mail to outside world i.e gmail i see this error in the mail queue (differed)
What could be the problem?Code:Host or domain name not found. name service error for name=gmail.com type=mx: host not found, try again
There are several problems with your configuration, according to a dig command from my server your server is not on that IP address. The second problem is that IP address is a private LAN IP address and (I assume it's running in a VM) it's not visible to the external world. Third, you will need a Split DNS set-up for your server to work correctly.
Do i need to configure Split DNS if i decide to place the server outside the LAN. (that means it will be directly accessible to the internet.
Regards
What's wrong with installing a Split DNS in your current environment and forwarding the necessary ports to the server? A hint - it's more secure than being directly on the internet. ;)Quote:
