Hi.

I am finally trying to install Zimbra (Red Hat Enterprise Linux 5 x86 64 bit) on CentOS 5.

I went through CentOS 5 howto, but getting error at the beginning of the installation:
Code:
The system will be modified.  Continue? [N] Y

Shutting down zimbra mail

Removing existing packages

   zimbra-core...done

Removing deployed webapp directories
Installing packages

    zimbra-core......zimbra-core-4.5.6_GA_1044.RHEL5_64-20070710170037.x86_64.rpm...FAILED
###ERROR###

zimbra-core-4.5.6_GA_1044.RHEL5_64-20070710170037.x86_64.rpm installation failed

Installation cancelled
I have A record pointed to the server, but I don't want to point MX record to this server yet, because I need to receive emails on another mail server.

Can anyone advise?

Jiri
