Zimbra - Restrict mail sending for subdomain
I am having trouble configuring Zimbra to restrict sending for some users. A subdomain has been added in the ZCS web page for the domain, resulting in two potential mail addresses:
The subdomain needs to be restricted from sending mail to the outside world and to other users on the same subdomain. It should only be able to message users on the main domain. The users on the main domain should be able to email anyone in the world.
Is it possible to configure this without installing Zimbra on two machines?
