Zimbra 9 Open Source build by Zextras


Everyday, Zextras builds Zimbra and Zextras towards Zimbra: since the rise of our company, we have always written code that is integrated into Zimbra. The deep knowledge of Zimbra gave us the confidence to take the responsibility of building and maintaining a professional Zimbra 9 Open Source based on Zimbra’s official repositories: welcome to the Zimbra 9 Open Source build by Zextras.

A message from Paolo Storti, CEO @ Zextras

In the late ‘90s I’ve started to work as Linux System administrator. Lately I’ve focused on providing Open Source email solutions: during this period, the struggle is real. Integrating and maintaining a multitude of heterogeneous components was an ongoing challenge, nights and days spent on finding the way to provide a suitable solution.

Some years later Zimbra broke into the scene and this was definitely the turning point for me: I immediately fell in love with the chance to provide a solution maintained as a single project in which all the pieces fit perfectly together.

As a communication systems fan and Open Source supporter, I’ve found in Zimbra everything I’ve always dreamt of. This is the reason why I’ve decided to give continuity to this project I strongly believe in, by making available the Zimbra 9 Open Source build by Zextras.
