Realtime Backup & Restore New in 8.8

Zimbra’s new realtime backup and restore engine backs up every single item and event on your server with split second precision. It’s designed to avoid data loss using atomic and ever-consistent algorithms, while still saving disk space — up to 50% — thanks to an intelligent deduplication and compression system. It offers six restore features, from a single-item restore to complete disaster recovery. All of the restore modes are transparent to the end-user and are 100% OS, architecture and version independent.

Hierarchical Storage Management (HSM) New in 8.8

Featuring advanced Zimbra store management and HSM, you can now manage multiple volumes and HSM policies through your Zimbra Administration Console. Save up to 50% of your valuable storage space, easily expand your Zimbra server by adding new volumes at will and improve your server performances by splitting the I/O load onto different storage media and use different tiers of storage equipment.

Mobile Sync New in 8.8

What’s new about Zimbra’s mobile sync functionality? Users can now sync their shared Zimbra items along with all of their other Zimbra data. Using Exchange ActiveSync protocol, which is natively supported by the vast majority of mobile devices, your data will always be at your fingertips, without any middle-ware or dedicated client.

Simplified Delegated Admin New in 8.8

In minutes, you can now grant Delegated Admin rights to users, allowing them to perform management tasks such as setting quotas, COS and user limits for your domains. Keep track of your Delegated Admins’ actions and your domain status with new reporting features, straight from your Zimbra Administration Console thanks to the dedicated Administration Zimlet.

Reconfigured IMAP Service Beta in 8.8

Have you had performance issues or outages due to IMAP usage? Zimbra 8.8 has refactored IMAP services to run separately from all other Zimbra services. IMAP will no longer affect your company’s SLAs! Zimbra 8.8 also has improved SIEVE RFC compliance, offering administrators greater email filtering.

Two-factor authentication

Zimbra includes now two-factor authentication, making your Mailbox more secure by providing a physical layer to produce a successful and secure login.

SSL SNI for HTTPS

Zimbra SSL SNI allows the server to present multiple certificates on the same IP address and TCP port number, so multiple hostnames can be served over HTTPS from the same IP address.

Postscreen for Zimbra MTA boosts Email Security

Keeping spambots away, Zimbra Postscreen leaves more SMTP server processes available for legitimate clients, and delays the onset of server overload conditions.

Zimbra Collaboration Packaging System

Apply security patches and Zimbra updates easier than ever before. Simply use your OS update commands, and all of your Zimbra packages will be updated as well.

S/MIME Digital Signatures and Encryption

Zimbra Collaboration Network Edition provides cryptographic security services for email: authentication, message integrity, non-repudiation of origin (using digital signatures) and privacy and data security (using encryption).

Unified Communications Integration

Now unified communications are built into Zimbra with an all-new voice application that features out-of-the-box integration with Cisco and Mitel UC solutions accessible through the main user interface.

Archiving and Discovery

Zimbra Archiving and Discovery is an optional feature that enables you to archive messages that were delivered to or sent by Zimbra Collaboration and to search across mailboxes. It’s specially designed for legal and audit purposes.

Outlook Sync using MAPI (Zimbra Connector)

If some of your users work with enterprise email clients like Microsoft Outlook, Zimbra provides a MAPI connector that allows your users to see their entire mailbox.

Exchange Web Services

If your users are using an enterprise email client like Microsoft Outlook in Mac OS X, Zimbra provides Exchange Web Services (EWS), which allows your users to connect to their mailbox in their favorite operating system.
