I wanted to create a distribution list named testlist@mydomain.net

Create the list

zmprov cdl testlist@mydomain.net

Set the reply-to as feedback@mydomain.net, the reply-to display name as Feedback. Force approval for subscriptions and unsubscriptions and hide the list in the GAL

zmprov mdl testlist@mydomain.net zimbraPrefReplyToEnabled TRUE zimbraPrefReplyToAddress feedback@mydomian.net zimbraPrefReplyToDisplay Feedback zimbraDistributionListSubscriptionPolicy APPROVAL zimbraDistributionListUnsubscriptionPolicy APPROVAL zimbraHideInGal TRUE

Set the list owner (needed for subscription and unsubscription messages) to be hostmaster@mydomain.net. To do so, we must have the zimbraId of the list owner (not the email address)

zmprov ga hostmaster@mydomain.net zimbraId | grep zimbraId | awk -F "zimbraId: " {'print "zmprov mdl testlist1@sepb.net +zimbraACE \""$2" usr ownDistList\""'} | bash

Now,  prohibit everyone in the world from sending to the list, then permit only a selected user to send

zmprov grr dl testlist@mydomain.net all -sendToDistList
zmprov grr dl testlist1@mydomain.net usr customerservice@mydomain sendToDistList
zmprov grr dl testlist1@mydomain.net usr customerservice@mydomain  sendAsDistList
zmmilterctl restart

Add members to the list

zmprov adlm testlist@mydomain.net user1@mydomain.net

Other useful commands

Remove members to the list

zmprov rdlm testlist@mydomain.net user1@mydomain.net

list all the parameters in the distribution list

zmprov gdl testlist@mydomain.net

list only distribution list members

zmprov gdlm testlist@mydomain.net

if need be – rename it

zmprov rdl testlist@mydomain.net somelist@mydomain.net

And in case you dont need it any more – delete it

zmprov ddl testlist@mydomain.net

Get all distribution lists

zmprov gadl
