Synacor Announces Zimbra Collaboration 8.7 Release, with Enhanced Features for Global Enterprises and Service Providers

Zimbra Collaboration 8.7 is here!

Zimbra Collaboration 8.7 is specifically enhanced for global enterprises and service providers, including Two-Factor Authentication (2FA), a new Zimbra Packaging System, SSL Server Name Identification (SNI), and Zimbra Postscreen, and all delivering a low total cost of ownership (TCO).

Key Enhancements offered 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.
  • With the new packaging system in Zimbra Collaboration 8.7, applying security patches and Zimbra updates are easier than ever before. When a new vulnerability arises, it’s simple updating of individual Zimbra components instead of the entire Zimbra package (typically a full upgrade).
  • <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.

Please, read the Full Release Notes here.

All Zimbra Collaboration 8.0.x and 8.5/8.6 sites are recommended to upgrade to have the latest packages.
