i am installing Zimbra 5.0.4 on RHEL ES 4. I am getting an error which says "DNS Error resolving MX for
. It is suggested that domain name have an MX record configured in DNS. Change domain name?" I have the following questions about this error.
1) What does this error mean?
2) My host is not actually an email server yet so it may not already have an MX record configured in the primary DNS. How do I confirm what A and/or MX record s are configured at the DNS for this host? Is there any command that I can run on the host to query the DNS?
3) If I do not want to change the domain name at this time and just skip this step, will the installation eventually fail or will there be any problem later on? If yes, what kind of problems.
4) If i want to change the domain name, what should it be? should it be something other than the current domain name? how do I put correct value so that the error goes away?
