Zimbra, also known as Zimbra Collaboration Suite or ZCS, is a group collaboration software package developed by Zimbra, Inc.
It is available free of charge as an open source package or as a commercial “Network Edition” that includes technical support.
The suite consists of server software that provides email, group calendars, and document sharing.
You can also sync data with mobile devices, such as BlackBerry, Windows Mobile, Android, and iPhone.
At SOLUTECSA we use mail and collaboration servers in Zimbra for dedicated server clients. We also do the installation of digital certificate in the Zimbra and maintenance.
