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:
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.
The system will be modified. Continue? [N] Y
Shutting down zimbra mail
Removing existing packages
Removing deployed webapp directories
zimbra-core-4.5.6_GA_1044.RHEL5_64-20070710170037.x86_64.rpm installation failed
Can anyone advise?
