I'll need to know what version of CentOS you are running, as well as what version of postfix you are running. I'll also need to get your postfix config files. OS-wise I will need /etc/sysconfig/network-scripts/ifcfg-eth0 and etc/resolv.conf. I'll set up a Virtual Machine with these settings changed to be local only, and go from there. If there is nothing obvious in the config files we'll have to do some trial and error live if I can't reproduce the error on my Virtual Machine. My thought is after you provide the info, I'll set up a VM and see what I can I see. If I solve it in less than 2 hours then $175 NZD will be the fee. If it is going to take longer I'll let you know what I found out, and we can re-negotiate from there.
