I know this has been covered several times, but I am not finding the correct answer for my situation...
I have a ZCS server setup with mydomain.com, its behind a firewall/router, but there is only one ip coming in so I have no need for split dns. Everything has worked great for several years and continue to works great to date.
I am now thinking about expanding and adding new companies/urls to the existing server, they each want an email system in place.
Am I better off just setting up aliases for all the new urls?
Setting up split dns?
or do I need a new ZCS for each url?
Ubuntu server 12.04.2 LTS
ZCS 8.0 (upgrading to 8.4 in a few months)
Mydomain.com -> ZCS server
