When a message is tagged as spam, the message is delivered to the recipient’s Junk folder. Users can view the number of unread messages that are in their Junk folder and can open the Junk folder to review the messages marked as spam. If you have the anti-spam training filters enabled, when they add or remove messages in the Junk folder, their action helps train the spam filter. See [[Zimbra MTA]] “Anti-Spam Protection”.

====HSM====

<div class="Body">
+
 
+
(''Network Edition Only'')
+
Hierarchical Storage Management (HSM) can be configured as a secondary storage volume for older messages. To manage your email storage resources, you can implement a different HSM policy for each mailbox server. Messages and attachments are moved from a primary volume to the current secondary volume based on the age of the message. Users are not aware of any change and do not see any noticeable difference when opening an older message that has been moved.
+
 
+
</div><div class="Body">
+
 
+
The message age threshold for HSM can be set globally from the HSM tab or for individual servers from the Server, Volume tab.The thresholds configured on individual servers override the threshold configured as the global setting.
+
 
+
</div><div class="Body">
+
 
+
Sessions to move messages to the secondary volume can be scheduled in your cron table and you can manually start a session from the administration console, Servers, Volume tab. From the administration console you can manually start a session, monitor sessions, and abort sessions that are in progress.

====Authentication Modes====
+
 
+
</div><div class="Body">
+

Authentication is the process of identifying a user or a server to the directory server and granting access to legitimate users based on user name and password information provided when users log in. Zimbra Collaboration Suite offers the following three authentication mechanisms:

==Managing Servers==
+

A server is a machine that has one or more of the Zimbra service packages installed. During the installation, the Zimbra server is automatically registered on the LDAP server.

</div><div class="Body">
+
 
+
You can view the current status of all the servers that are configured with Zimbra software, and you can edit or delete existing server records. You cannot add servers directly to LDAP. The Zimbra Installation program must be used to add new servers because the installer packages are designed to register the new host at the time of installation.

Search is used to quickly locate individual accounts, aliases, distribution lists, and resources on the LDAP server. Search by display name, first name, last name, the first part of the email address, alias, or delivery address. If you do not know the complete name, you can enter a partial name. Partial names can result in a list that has the partial name string anywhere in the information.

You can also use the Zimbra mailbox ID number to search for an account. To return a search from a mailbox ID, the complete ID string must be entered in the search.

For provisioning many accounts at once, you create a formatted text file with the user names. This file runs through a script, using the CLI command, <span class="Code">zmprov</span>. The <span class="Code">zmprov</span> utility provisions one account at a time.
+
 
+
</div><div class="Body">
+

Create a text file with the list of the accounts you want to add. Each account should be typed in the format of ca (Create Account), email address, empty password. For example,<span class="Code"> ca name@company.com ‘’</span><span style="font-style: italic;">’</span>

<span class="Bold">Note: </span>In this example, the empty single quote indicates that there is no local password.

===Distribution Lists===

A distribution list is a group of email addresses contained in a list with a common email address. Distribution lists can be added, changed and deleted from the administration console.

===Class of Service===
+
 
+
</div><div class="Body">
+
 
+
Class of Service (COS) is a Zimbra-specific object that determines what default attributes a Zimbra Web Client email account has and what features are added or denied. The COS controls mailbox quotas, message lifetime, password restrictions, attachment blocking, and server pools for creation of new accounts.
+
 
+
</div><div class="Body">
+
 
+
A default COS is automatically created during the installation of Zimbra software. You can modify the default COS to set the attributes to your email restrictions, and you can create new COSs to assign to accounts.
+
 
+
</div><div class="Body">
+
 
+
Each account is assigned one class of service. When an account is created, if the COS is not explicitly set, the default COS is assigned. Also, if the COS assigned to the user no longer exists, the account is automatically assigned the default COS.
+
 
+
</div><div class="Notice">
+
 
+
<span class="Bold">Note: </span>COS settings assigned to an account are not enforced for IMAP clients.

</div><div class="Body">
+
 
+
A COS is global and is not restricted to a particular domain or set of domains.
+
 
+
</div><div class="Body">
+

Assigning a COS to an account quickly configures account features and restrictions. Some of the COS settings can be overridden either by global settings or by user settings. For example:

====Distributing Accounts Across Servers====

+
</div><div class="BodyAfterHead">
+
 
+
In an environment with multiple mailbox servers, the class of service is used to assign a new account to a mailbox server. The COS server pool tab lists the mailbox servers in your Zimbra environment. When you configure the COS, you select which servers to add to the server pool. Within each pool of servers, a random algorithm assigns new mailboxes to any available server.

A resource is a location or piece of equipment that can be scheduled for a meeting. The resource has its own mailbox address and accepts or rejects invitations automatically. Accounts with the Calendar feature can select resources for their meetings.
+
 
+
</div><div class="Body">
+
 
+
You create resources and manage their use from the administration console. A Resource Wizard guides you through the resource configuration, including designating the type of resource, the scheduling policy, the location, and a description.
+
 
+
</div><div class="Body">
+
 
+
To schedule a resource or location, users invite the equipment and/or location to a meeting. When they select the resource, they can view the notes about the resource and view free/busy status for the resource, if set up. When the meeting invite is sent, an email is sent to the resource account, and if the resource is free, the meeting is automatically entered in the resource’s calendar.
