Unknow host when using ping..
Hi,I'm setting up a test server and I already installed apache, mysql, php, mydns, proftpd, and now just installed postfix. website is doing fine.
The problem is I can send and received emails and when I checked, I got an error in the log:
(Host or domain name not found. Name service error for name=domain.com type=MX: Host not found, try again)
And when I try to ping in ssh, I got an ping:unknown host:domain.com
Can somebody help?
