Zimbra Distribution-list Restriciton

Generally we need to use distribution lists for our regular email communication. Our management may circulate any message to all stuffs which we can fulfill by configuring a distribution list in a mail server. But the problem is when a user replies on a mail received via distribution list it has been delivered to all the members of that distribution list which is not expected.

To stop the users sending emails to a distribution list or restrict it to specific person we have to configure the restriction which is given below.

Step 1: Enable Milter Server from Zimbra Administration Console.
Path: Zimbra Admin Console >> Configure >> Global Settings >> MTA

Step 2: Set a owner of the distribution list you want to set the restriction.
Path: Zimbra Admin >> Manage >> Distribution List >> Select Distribution List >> Owner

Step 3: Login the web console of the owner and set the restriction as required.

Path: Owner web console >> Contacts >> Distribution List >> Right click the targeted list and Click Edit distribution list >> Distribution list Properties.

Set your required restriction and save it.
