"Zimbra - the leader in next-generation messaging and collaboration"

Zimbra is a dual license (open source and commercial version) email and messaging system.

Basic Features

Behind the scenes

• Uses many open source products
  • Database: mysql, Lucene, Sleepy Cat
  • Apache (new version uses built in Java http server)
  • Postfix SMTP
  • Clam AV
  • Amavis
  • Open LDAP
  • and lots more
• Manages the packages
  • Controls the operating system
  • Uses native package system, but not native packages
  • Does not play well with others
  • But that can be good - as it offers better control (automatic) of dependencies
• Virtual Servers
  • Shared virtual servers like Zones (solaris) and vservers (linux) have difficulty
  • Mostly this is due to bindings to localhost and security
