1&1 partners with Open-Xchange Inc. to deliver powerful hosted email and collaboration solutions

London - 1&1 Internet, the world's largest web host by known servers, today announced a strategic partnership with leading messaging and collaboration solutions provider Open-Xchange Inc. 1&1 will base its forthcoming range of hosted email and collaboration packages upon Open-Xchange Inc.'s award winning Smart Collaboration(tm) technology.  The move is indicative of 1&1's progression within the global 'Software as a Service' (SaaS) market.  The company's mass roll-out of Open-Xchange technology represents 1&1's confidence in open-source alternatives, and its commitment to the open-source community.

1&1 will utilise the Open-Xchange platform for a range of 1&1 branded MailXchange email and collaboration packages to be launched worldwide. Available first in Germany as of today, and subsequently in UK, France and US, 1&1 MailXchange will within the first half of 2007 offer the full set of personal information management ("PIM") functionality - email, calendaring, contacts and task management together with advanced groupware features such as Documail and Smart Document Sharing.  The solutions will deliver valuable functionality for small businesses and individuals, enabling remote working and communication at very low price points.  1&1 MailXchange accounts will be available as a stand-alone package and as a bolt-on for existing hosting customers.

1&1's use of an open-source platform will equip customers with the very latest features at a much lower price than comparable products. Open-Xchange provides high performance and reliability and offers 1&1 greater scalability than similar licensed solutions. The open-source nature of the solution facilitates seamless integration within 1&1's back-end email systems. Moreover, Open-Xchange's open standards and APIs (Application Programming Interface) enabled a seemless integration into 1&1's business processes, such as user provisioning, systems management and billing processes.

Recent years have seen a significant increase in the popularity of open-source solutions for professional users.  A high profile example is the City of Munich, Germany, which adopted open-source office solutions for its thousands of civil service workers.  Products like 1&1 MailXchange have the 'look and feel' of similar mainstream licensed products and are easily adopted by all levels of user.

Andreas Gauger, CEO 1&1 Internet, said "Our partnership with Open-Xchange is an important and valuable milestone in our open-source journey.  Open-source applications have always been of interest to us, but the Open-Xchange offering now shows that open-source has matured to the level where it offers an excellent mainstream email and collaboration product."

For 1&1, the partnership comprises a further stride into the 'Software as a Service' (SaaS) market.  Gauger added, "1&1 will continue to call upon open-source channels where it is clear that our customers could benefit from innovation and greatly reduced licensing costs".

"This is an historic milestone for 1&1 as well as for Open-Xchange as hosted collaboration solutions will clearly be the pace makers for hosters on their way to application service providers", said Frank Hoberg, CEO of Open-Xchange.  "The benefits for small and medium sized customers are just too compelling.  They benefit from easy to use, state of the art business software that really simplifies their businesses for unrivalled costs - without initial investment or ongoing administration efforts".

1&1 has a long and distinguished past in contributing to open-source innovation.  Since 1995, the company has invested in developing open-source technologies for web hosting.  1&1 was a supporting partner of the very successful NoSoftwarePatents campaign and continues to contribute to open-source projects that are driving the web solutions industry.
