The Zing in Zimbra
Nathan Torkington - The Zing in Zimbra:
"The server platform is the Microsoft Exchange killer we've all wanted. There's an ocean of people who want the Exchange feature set without the Exchange nightmares: administration, performance, and security. The folks at Zimbra have released it as open source, not just the Ajax client and the toolkit used to build it, but the server as well. [...] The Zimbra server ties together Postfix, MySQL, OpenLDAP, Tomcat, and more, building an integrated platform out of what used to be a patchy chaotic mix of protocols, libraries, and file formats."
