A distribution list is a group of email addresses contained in a list with a common email address. When users send to a distribution list, they are sending the message to everyone whose address is included in the list. The address line displays the distribution list address; the individual recipient addresses cannot be viewed. Only administrators can create, change, or delete distribution lists.
The maximum number of members in a distribution list is 1000 recipients. The 1000 recipients include addresses in distribution lists that are nested within a distribution list. Senders do not receive an error when they send a message to a distribution list with more than 1000 members, but the message is not sent to more than 1000 recipients.
When a Zimbra user’s email address is added to a distribution list, the user’s account
Member Of tab is updated with the list name. When a distribution list is deleted or the removed, the distribution list is automatically removed from the
Member Of tab.
The Hide in GAL check box can be enabled to create distribution lists that do not display in the Global Address List (GAL). You can use this feature to limit the exposure of the distribution list to only those that know the address.
Instead of creating individual share requests, distribution lists can be created to share items with a group. Users notify the administrator that they have shared an item with the distribution list and the administrator publishes the shared item to the list. This is done in the Shares tab. When a new shared item is published, existing members of the list are automatically notified of the new share.
When new members are added to the group distribution list, they are automatically granted the same shared privileges as other members of the group. You can set up the Share tab so that new members are automatically notified about items that are shared with them through the list.
