I am trying to set up Zimbra so that people who have internal email address can not send out of the nextwork and stay in house.
In the same respect, I would like to setup some users that have both internal and external accounts but if they use an external account the get the external from clause so that people in the outside world can reply to the email.
Has anyone tried this? Is it possible with Zimbra? Thanks for you help from a new and impressed user of Zimbra.
