Domain versus Virtual Daomains
Can someone clarify for me the difference between adding a new domain and a virtual domain.
Well more precisely....why the difference?. An MTA can only have one domain under the IP, so wouldn't *anything* else _be_ a virtual domain under that domain?
Is Zimbra spawning a separate MTA for each domain?
If one has only one server, which only has one IP address, then technically would you not want only _one_ domain?
And how dose one configure the DNS to respond correctly to a reverse lookup on an IP address that is hosting a virtual domain? My question comes from the following scenario:
Domain:domain.com IP:18.104.22.168 FQDN:mail.DOMAIN.com
Now if I send mail from the virtual.com the receiving MTA will do a reverse lookup for that domain's MX. Which will be mail.virtual.com [22.214.171.124]
However, a reverse lookup of 126.96.36.199 will result with mail.DOMAIN.com. How do you get around that?
thanks in advance
