Right now I have two virtualmin servers running (main1.mydomain.com and main2.mydomain.com) and a mail server running Zimbra on another server (mail1.mydomain.com).
So far, I've got both of them pointing mail to the mailserver, so thats good.
However, I would like to be able to use main1.mydomain.com as a nameserver, I think its called, so that I can point all my clients to that servers IP/FQDN and then that server decides if that clients website is on main1 or main2, and work accordingly (forward to server, or display website, or whatnot)
Can I do this ? Will it be better to purchase another server ? Can I keep main1 as a shared hosting server as well as a nameserver for both main1 and main2? Will I need to setup LDAP for this?
