I am trying to install ZCS 7.1.0 RHEL5_64 in my CentOS 5.5 64bit with the --platform-override. Everything goes fine until my DNS resolvation.
My hostname is mail.myfriend.co.in and my DNS records are managed by my domain registrar. The A record points to my public IP. and the MX record mail.myfriend.co.in also points to my public IP. I have done port forwarding of port numbers 22, 25, 80, 443, 143, 993, 110, 995, 389, 7025, 194 to my local IP 192.168.2.25.
Here i have attached my installation procedure and the error msg. as a text file (dns-resolvation). and also i here are the entries in my /etc/hosts file and the /etc/resolv.conf file.
127.0.0.1 localhost.localdomain localhost
18.104.22.168 mail.myfriend.co.in mail
please look for the error in the attachment and guide me. what is the additional configuration has to be done.
