Highlight new Features in Zimbra Collaboration 8.7
The security of each individual user is a prerequisite in most enterprises. Zimbra Collaboration 8.7 includes a native 2FA feature that doesn’t require a plugin at the server or user level, and works with the most well know OTP mobile applications. With 2FA, two components are required to log into an email account—something the user knows: a password, user ID, etc., and something the user possesses: a smartphone or USB-key.
SSL SNI for HTTPS
Customers and Business Service Providers (BSP) hosting multiple Zimbra domains now have official support for Multiple SSL domains on a single server (SNI) for HTTPS connections. With 8.7 it is now possible to publish multiple SSL Certificates using one single IPv4.
Postscreen for Zimbra boosts Email Security
Zimbra Collaboration 8.7 comes with postscreen at the MTA-level. The postscreen daemon provides additional protection against mail server overload. By keeping spambots away, postscreen leaves more SMTP server processes available for legitimate clients and delays the onset of server overload conditions.
Highlight new Features in Zimbra Collaboration 8.5/8.6
High Fidelity Document Preview
High Fidelity Document Preview is a Network Edition feature that permits preview it regular document files using the Libreoffice engine.
All the supported type documents are converted into a .pdf file, and then any browser with the PDF viewer enabled, or Adobe Reader installed, can preview the files.
DNS caching service (dnscache)
Starting with Zimbra Collaboration 8.5 and above, there is now a DNS caching service available for installation. It is specifically targeted for MTA nodes, and could be perfect for Single-Server Installations.
Three of our supported features are raly heavily on DNS lookups: DKIM verification, SpamAssassin Scoring, Postfix RBLs for spam blocking.
Zimbra Offline Mode allows you to use the Zimbra Web Client (ZWC) and access your data without network connectivity. For example, if server connectivity is lost, ZWC automatically transitions to “offline mode”.
When server connectivity is restored, ZWC automatically reverts back to “online mode”.
The Touch Client is a Network Edition feature that enables a new web client interface for a mobile device. It uses the Sencha Touch Mobile HTML5 Framework optimized for the canvas of a smartphone or tablet device.
When a client first connects to a mail server via a web browser, the server attempts to detect the client type.
Exchange Web Services
Exchange Web Services was released in ZCS 8.5 or above and is a Network Edition feature that need to be purchased separetly. With this feature you can connect devices or applications that support the EWS technology.
PCI Compilance and Cipher strength
Starting with ZCS 8.5, it is possible to configure the TLS related strength factors for postfix to not only enforce encryption but to enforce a certain strength of encryption.
With ZCS 8.5 and later, it is now possible to preserve PCI compliance configuration across upgrades.
Separation of WebApp from Mailtstore
The current Zimbra architecture combines the mailstore functionality with all the web functionality on the same server.
Aim is to split the combined functionality so that mailstore server can be run independently from web that includes Zimbra Web Client, Zimbra Admin Client and Zimlets.
Exchange ActiveSync was released in ZCS 8.5 or above and is a Network Edition feature. With this feature you can connect devices or applications that support the EAS technology.
