Inbound Internet mail goes through a firewall and load balancing to the edge MTA for spam filtering. The filtered mail then goes through a second load balancer. An external user connecting to the messaging server also goes through a firewall to the second load balancer. The inbound Internet mail goes to any of the Zimbra MTA servers and goes through spam and virus filtering. The designated Zimbra MTA server looks up the addressee's directory information from the Zimbra LDAP replica server. After obtaining the user's information from the Zimbra LDAP server, the MTA server sends the mail to the appropriate Zimbra server. Internal end-user connections are made directly to any Zimbra server which then obtains the user's directory information from Zimbra LDAP and redirects the user as needed. Zimbra servers' backups can be processed to a mounted disk.

Zimbra Mailbox Server
The Zimbra mailbox server is a dedicated server that manages all of the mailbox contents, including messages, contacts, calendar, Briefcase files and attachments. Topics in this chapter include: Incoming Mail Routing Messages are received from the Zimbra MTA server and then passed through any filters that have been created. Messages are then indexed and deposited into the correct mailbox. Each Zimbra mailbox server in the system can see only its own storage volumes. Zimbra mailbox servers cannot see, read, or write to another Zimbra server. In a ZCS single-server environment, all services are on one server, and during installation the computer is configured to partition the disk to accommodate each of the services. In a ZCS multi-server environment, the LDAP and MTA services can be installed on separate servers. See the Multi-Server Installation Guide.
Incoming Mail Routing
The MTA server receives mail via SMTP and routes each mail message to the appropriate Zimbra mailbox server using LMTP. As each mail message arrives, the Zimbra server schedules a thread to have Lucene index it.

The mailbox server includes the following volumes:
Message Store. Mail message files are in opt/zimbra/store Data Store. The MySQL database files are in opt/zimbra/db Index Store. Index files are in opt/zimbra/index Log files. Each component in ZCS has log files. Local logs are in /opt/

The values of the object class attributes determine the schema rules the entry must follow. The attributes allowed for an entry are determined by the object classes associated with that entry. would be an account. LDAP Hierarchy LDAP directories are arranged in an hierarchal tree-like structure. For example. and auxiliary object class zimbraAccount. In the Zimbra system. An entry's object class that determines what kind of entry it is. either administrator or end-user. The object classes determine what type of object the entry refers to and what type of data can be stored for that entry. and what types of attributes they have. instead. is called a structural object class and cannot be changed. it uses the DNS server's MX entry to determine where to direct mail.0 Zimbra Collaboration Suite . 28 Open Source Edition 7. Other object classes are called auxiliary and may be added to or deleted from the entry. An entry with the object class zimbraServer would be a server in the Zimbra system that has one or more Zimbra packages installed. An LDAP directory entry consists of a collection of attributes and has a globally unique distinguished name (DN). the structure is arranged based on Internet domain names.Administrator's Guide MTA does not connect to the LDAP database. an entry with structural object class inetOrgPerson. which in turn connects to LDAP LDAP Directory Traffic edge MTA DNS Zimbra MTA Zimbra LDAP directory server Zimbra mailbox server Zimbra command-line tools Zimbra Web Client UI At the core of every LDAP implementation is a database organized using a schema. Use of auxiliary object classes in LDAP allows for an object class to be combined with an existing object class. The schema specifies the types of objects that are stored in the database. The Zimbra clients connect through the Zimbra server.

using the zimbraAuthMech attribute. The External LDAP and External Active Directory authentication methods attempt to bind to the specified LDAP server. using a pool of re-usable administrator LDAP connections. the default is to use the internal method as the authentication. If this attribute is not set. External LDAP and External Active Directory Authentication Mechanism Unlike the internal authentication mechanism. This requires that users exist in both OpenLDAP and in the Active Directory servers. with other information also coming from the domain.Administrator's Guide Note: You cannot modify the Zimbra schema. This should be in the form: 30 Open Source Edition 7.0 Zimbra Collaboration Suite . Internal Authentication Mechanism For accounts stored in the OpenLDAP server. Account Authentication This section describes the following account authentication mechanisms and formatting directives that are supported: Internal External LDAP External Active Directory The Internal authentication method assumes the Zimbra schema running on the OpenLDAP directory server. These methods can be used if the email environment uses Microsoft Active Directory directory services for authentication and the Zimbra-LDAP directory services for all other Zimbra-related transactions. using the supplied user name and password. This information is not used to connect to the directory server. If this bind succeeds. the userPassword attribute stores a salted-SHA1 (SSHA) digest of the user's password. The authentication method type is set on a per-domain basis. it is only used to compare with the information on the OpenLDAP server. Two additional domain attributes are required for the external mechanism: zimbraAuthLdapURL and zimbraAuthLdapBindDn. the external authentication mechanism attempts to bind to the directory server using the supplied user name and password. zimbraAuthLdapURL Attribute and SSL The zimbraAuthLdapURL attribute contains the URL of the Active Directory server to bind to. the connection is closed and the password is considered valid.
Zimbra Directory Service ldap://ldapserver:port/ where ldapserver is the IP address or host name of the Active Directory server. Preparing a domain for custom auth To enable a domain for custom auth. use ldaps: instead of ldap:. the user name starts out in the format: user@domain. Zimbra invokes the registered custom auth handler to authenticate the user. zimbraAuthMet to custom:{registered-custom-auth-handler-name}.zimbraCustomAuth You can implement a custom authentication on your domain. To set up custom authentication. You can also use the fully qualified host name instead of the port number. In the case of Active Directory. If the SSL version is used. Custom authentication allows external authentication to your proprietary identity database. the SSL certificate used by the server must be configured as a trusted certificate. set the domain attribute. zimbraAuthLdapBindDn Attribute The zimbraAuthLdapBindDn attribute is a format string used to determine which user name to use when binding to the Active Directory server.com The user name may need to be transformed into a valid LDAP bind dn (distinguished name). For example: zmprov modifydomain {domain|id} zimbraAuthMech custom:sample. and port is the port number. Custom Authentication . prepare the domain for the custom auth and register the custom authentication handler. Examples include: ldap://server1:3268 ldap://exch1. When an AuthRequest comes in. During the authentication process.com For SSL connection. In the above example.acme. Zimbra checks the designated auth mechanism for the domain. The default is FALSE. zimbraAuthFallbackToLocal Attribute The zimbraAuthFallbackToLocal attribute can be enabled so that the system falls back to the ZCS local authentication if external authentication fails. that bind dn might be in a different domain.

COM. If zimbraForeignPrincipal starts with "kerberos5:". zimbraAuthMech is set to kerberos5. For example: kerberos5:user1@MYREALM. the server constructs the Kerberos5 principal by {localpart-ofthe-email}@{value-of-zimbraAuthKerberos5Realm} and uses that to authenticate to the kerberos5 server. Zimbra Objects Zimbra uses auxiliary object classes to add Zimbra-specific attributes to existing objects such as an account. When users log in with an email password and the domain.Zimbra Directory Service Kerberos5 Authentication Mechanism Kerberos5 Authentication Mechanism authenticates users against an external Kerberos server. To set up Kerberos5 auth set the domain attribute zimbraAuthMech to kerberos5.0 33 . Kerberos5 can be supported for individual accounts. Set the account's zimbraForeignPrincipal as kerberos5:{kerberos5-principal}. the server uses {kerberos5-principal} as the Kerberos5 principal instead of the algorithm of grabbing the realm from the zimbraAuthKerberos5Realm as mentioned in the previous paragraph. The LDAP objects used in Zimbra include the following: Accounts Class of Service (COS) Domains Distribution Lists Recipients Servers Global Configurations Aliases Zimlet CalendarResource Identity Data Source Signature Zimbra Collaboration Suite Open Source Edition 7. Then set the domain attribute zimbraAuthKerberos5Realm to the Kerberos5 realm in which users in this domain are created in the Kerberos database. This is done by setting the account's zimbraForeignPrincipal as kerberos5.

and Spam Assassin SMTP Authentication SMTP authentication allows authorized mail clients from external networks to relay messages through the Zimbra MTA. Webmail MTA is used by the Zimbra server for composed messages and must be the location of the Postfix server in the Zimbra MTA package. Note: User authentication is provided through the Zimbra LDAP directory server. SMTP protocol violators (that is. DNS based restrictions are also available. clients that do not greet with a fully qualified domain name) are restricted. or if implemented. but those mail systems may be poorly implemented. You may want to receive mail from people outside of your mail system. ClamAV. Important: Understand the implications of these restrictions before you implement them. Such a destination SMTP server is commonly referred to as a relay or smart host. or if you have some filtering SMTP proxy server. Zimbra Collaboration Suite Open Source Edition 7. The user ID and password is sent to the MTA when the SMTP client sends mail so the MTA can verify if the user is allowed to relay mail.0 43 . SMTP Restrictions In the administration console. By default.

You may have to compromise on these checks to accommodate them. These restrictions provide some protection against ill-behaved spam senders. Relay host is the MTA to which Postfix relays non-local email. You can set this relay host from the administration console. you can enable restrictions so that messages are not accepted by Postfix when non-standard or other disapproved behavior is exhibited by an incoming SMTP client. through the Microsoft Active Directory Sever. Relay Host Settings Postfix can be configured to send all non-local mail to a different SMTP server. A common use case for a relay host is when an ISP requires that all your email be relayed through a designated host.

Overview of Zimlets
Zimlets were created as a mechanism to integrate ZCS with different thirdparty applications to enhance the user experience from the Zimbra Web Client. When Zimlets are added to the ZCS, users can look at information and interact with the third-party applications from within their email messages. With Zimlets, arbitrary message content can be made live by linking it with Web content and services on intranets or the Internet. Mousing over actionable content gives the user a real-time preview (subject to security constraints) that can be factored in decision making. For example, various Zimlets can be enabled to let users preview the following:
Mouse over a date or time and see what is in calendar. Mouse over a name or email address and see details from the address book for this name. Right-click on a phone number to make a call with your soft-phone. Right-click on a date to schedule a meeting. Right-click on a name, address, or phone number to update address book information.

Zimlets from the Zimbra Gallery
In addition to the default Zimlets included in your ZCS installation, you can also download and deploy Zimlets from the Zimlet Gallery, which is located on the Zimbra web site. See Deploying Zimlets on page 123 for more information on how to deploy Zimlets.
Developing Customized Zimlets
For information about how to develop your own custom Zimlets, see the Zimlet Developers Guide on the Zimbra Wiki. This is an extensive guide which shows you how to set up your development environment, create a basic Zimlet and learn the principles of building, debugging and deploying a Zimlet.
Deploying Zimlets
When a Zimlet is deployed, it is immediately available to everyone in the default COS. If a Zimlet is not deployed to another COS directly, the COS displays the Zimlets but they are not enabled. You can deploy Zimlets from the Admin console or the CLI, as described in this section.
Deploying a Zimlet from the Admin Console
To deploy a Zimlet from the Admin console:
1. From the Configuration>Zimlets view, click Deploy. The Deploying a
zimlet or an extension view displays.
2. Browse to the Zimlet zip file you want to upload and deploy. Click Deploy.
In the example below, we are deploying com_zimbra_apptsummary.zip.

Adding Proxy Allowed Domains to a Zimlet using the CLI
When deploying a Zimlet, the COS attribute, zimbraProxyAllowedDomains must be set for the domain address that the Zimlet might call to get information.
1. To set this attribute, type: zmprov mc <COSname> +zimbraProxyAllowedDomains <*. domain.com>
The * must be added before the domain.com. This must be applied to all COSs that have your Zimlet enabled.

Deploying a Zimlet and Granting Access to a COS
To deploy a Zimlet to one or more COSs other than the default:
1. Install the Zimlet, then adjust the ACL on the COSs. 2. Login as zimbra user: su – zimbra 3. Copy the Zimlet zip file from Gallery to /tmp folder. Or, select a zimlet from /opt/zimbra/zimlets-extra directory. 4. Run zmzimletctl deploy <path-to-zimlet.zip>. For example: zmzimletctl deploy /tmp/<zimlet>.zip
This will install the Zimlet just to default COS.
5. To deploy the zimlet to additional COS's, run: zmzimletctl acl <zimletname> <cosname1> grant
This will grant permission to cosname1. You can also grant access to more than one COS on the same command line. Enter as:
zmzimletctl acl <zimletname> <cosname1> grant <cosname2> grant 6. Finally, add zimbraproxyalloweddomain information by running the following
