I have moved (locations and providers) an email box using ES as a mail server. It worked fine before, but now stalls in the boot-up when "starting red hat daemon network." I presume that I have not correctly put in the new information for the new provider. Can you walk me through this? I have Comcast Cable (business) running to a Cisco 900, then to a smoothwall firewall box. The email server sets in the DMZ off the smoothwall box. The internal network is fine. And, I have an old box running Red Hat 7.2 that works fine, which I am using it in the meantime.
