How can I set up two completely different FQDNs (two totally different hostnames) on one box (e.g., my.domain.net & alsomy.otherdomain.net) so that this machine accepts traffic on my.domain.net while appearing to be alsomy.otherdomain.net to anyone who accesses it via the webserver or mailserver? ;-)
Do I need to run virtual hosting here? Will it work to point A records from each of those host names to the same, single IP address? Art
