Hello guyz, need some help setting up Zimbra. I'm stuck due to not fully understanding how to make my SMTP work and DNS setup. I will start off by explaining my network setup.
ADSL Router --> Firewall "192.168.0.254" --> Switch <--- Server OSX " 192.168.0.2" "DNS Zone = server.name.int" "Domain = name.int"
At the moment my email is hosted by hosting provider, and I would like to keep it that way so basically, I would like to setup Zimbra on its separate computer connect to switch place it on the LAN! behind the firewall, all the SMTP must go through the smtp on Firewall " 192.168.0.254". I do not understand how or what the DNS zone should be, do I need to create new zone or just add another machine entry mapping it to the Zimbra ip " 192.168.0.1" what should be entered in the resolve.conf and hosts what should be the hostname and domain name that I chose during the Zimbra setup.
Should I then just setup Zimbra for localuser and add external account for each email, the only difficulty with that is I was unable to send out emails..
PLease advise me on what can be done and how?
