Collax Business Server

Collax FlexibleIT_LogoThe IT infrastructure for SMEs

Collax Business Server is an all-in-one IT solution which provides all the communication, storage and security services an SME (Small to Medium Enterprise) may require.

It's a perfect alternative to Microsoft Small Business Server which will reduce by at least 50% your purchasing and maintenance costs while it provides more service and requires, thanks to its efficiency, servers with much lower specifications.

Collax Business Server can also replace a good number of devices like firewalls, faxes, storage servers and domain controllers so you'll be able to simplify your IT infrastructure, reduce your support and licensing costs while cutting also you electricity bill as you'll need only one low power server to perform all the tasks that where managed by different devices.

It can also be an excellent complement to existing IT set-ups as, being able to connect to Microsoft Active Directory, it can offload your main Windows server of some services maintaining a single authentication solution.

System administrators will find it very easy to manage a Collax Business Server as its comprehensive but easy to use web management interface provide total control over the server's features.  For easy and quick recovery, in case of hardware failure, all the configuration and data backup tools are included.

Zarafa Communication Platform integration

Zarafa Communication Platform integration

From a user point of view nothing changes, apart from the increase in services and responsiveness, and it can be used in mixed Windows, OS X e Linux environments.

E-mail, Fax, Instant Messaging, remote access and document sharing are just some of the services available to all authorised users.

To secure Internet access is possible to activate the built in web filtering features so that access will be restricted and filtered depending on the configured security levels based on user groups.


Collax Business Server, together with the Kopano Collaboration Platform add-on, can be seen as an enhanced version of Microsoft Small Business Server as it includes all the services you already know of MS SBS but it adds on top all the security and communication features which would otherwise require additional equipments and licenses.

The free version is fully featured but limited for up to 5 users.

Collax's family of products

Collax, your IT infrastructureCollax FlexibleIT_Logo

Collax has been making system administrators' life a lot easier for many years by standardising and simplifying the management of Linux servers. There is no need to edit complex configuration files or manage many servers with different Linux distributions and versions.

As Collax produces a family of products, covering most of the requirements SMEs may have, the interfaces and the methodologies used are very similar so once you learned how to use one product all the others are a lot easier to learn than having to deal with different manufacturers with different web interfaces.

Not just a Linux server management console

While most users will just notice a professionally designed web interface there is a lot more to it. To guarantee maximum uptime for your infrastructure Collax runs its own software repository where all the packages of its Debian based distribution are tested for bugs and compatibility with other add-on software that you may have installed on your Collax server.

A team of engineers is constantly busy developing new features and improving existing ones so that you can enjoy the robustness, efficiency and cost savings a Linux platform can deliver without the management complexity.

 Collaboration services for every needKopano - The best alternative to Microsoft Exchange and Office365

Organizations that are looking for a complete groupware package do not all need the same level of collaboration, performance and support. You can therefore obtain Kopano’s open source Collaboration Platform in various different editions.

Kopano Basic is ideal for SMEs as it includes all the features generally required by a smaller number of users and a cost that competes very well even against Cloud offerings.

Kopano Professionalis made for organizations that require advanced features such extended system analytics (through Kopano Dashboard), advanced Files for Teams and Web Meetings, email and phone support.

Kopano Enterpriseis targeted to organizations that need a clustered solution. The multi-server support can be used to support larger number of users or to spread mailboxes across different geographical locations. The Enterprise Edition combines the most extensive collaboration features with the highest level of support.

Do you use the Kopano Community Edition? Check out the table below to see how the Professional or Enterprise edition can add value to your organization. Keep also in mind that a small investment for your side helps in speeding up the development of the features you'd like to see implemented.

The following table presents a summary of the main differences between versions:

  Community Basic
Professional Enterprise
Outlook connector (MAPI) 3 users
ActiveSync (Z-Push)
IMAP/POP3 gateway

Kopano FAQ

Kopano - The best alternative to Microsoft Exchange and Office365Kopano - Yet another email and collaboration solution?

Many wonder why they should choose Kopano instead using the usual brands. Here we try to answer some of the questions. Do you want to ask some more? Then don't hesitate to contact us.

Isn't Microsoft Exchange good enough?

While Microsoft Exchange provides the features required by most businesses it is also quite expensive to purchase, it requires powerful servers and it doesn't allow very easily to integrate with other applications not produced by Microsoft. With the latest releases it is not even possible any more share public folders and calendars without purchasing SharePoint adding more complexity and costs.

Google Apps or Office365?

Cloud based collaboration offering may seem very interesting as you don't have to pay upfront for software and servers but comparing the costs over 2/3 years Kopano will cost you about 50/70% less (including the infrastructure and support costs), it will allow you to keep control of your data and to integrate it with your applications.

Kopano already includes video conference, instant messaging, secure file sharing, email encryption and many more features. It's faster, it requires little maintenance and HW resources, it requires lower investments than Cloud based products so why choosing something else?

Then, with the recent and ongoing PRISM/NSA scandal and Cloud services downtime (wasn't the Cloud supposed to provide 100% uptime?), do you really want to give away your valuable data and pay for it?

Kopano joins The Document Foundation

Kopano collaboration platformKopano joins The Document Foundation Advisory Board

Kopano logo150x35 + The Document Foundation - LibreOffice

From The Document Foundation blog


Berlin, September 26, 2017 – The Document Foundation (TDF) announced today that Kopano, the leading European provider of open source groupware and collaboration software, has joined the project’s Advisory Board. Kopano wants to contribute to the project in areas of its expertise, for example in user experience.

Kopano is a continuation of Zarafa. It offers a platform for communication, content sharing and self-organization, is entirely modular, and provides third party software vendors with simple integration options (e.g. via widgets).

Most features and integrations are available via a browser, thanks to Kopano WebApp, while smartphones, tablets and Outlook can be connected through Z-Push – the open source implementation of the Exchange ActiveSync Protocol (EAS). Kopano’s desktop client DeskApp is available for Windows, macOS and Linux.

Solutions like Kopano, combined with LibreOffice, help users to free themselves from the dependency of Microsoft and other cloud software, and enable companies to retain freedom and ownership of their data and software stack.

Zarafa becomes Kopano

Kopano collaboration platformKopano is the new Zarafa!

After over 10 years of activity and development Zarafa decided that it was time for a new name and fresh look to mark also the moment when its flagship product has been officially released with a brand new look and features.

Kopano is not just a new identity but also a new communication platform that has been over time rewritten and modernised to compete in a "Cloudified" world.

Some may like the convenience of working on third party public Cloud applications but once they discover Kopano offers the same convenience but adds to it the freedom of integrating it with other applications, the fact that the data is back under their control and it also costs less than Office365 or G Apps then public Cloud doesn't seem that appealing any more.

Zarafa diventa Kopano

Kopano collaboration platformKopano è il nuovo Zarafa!

Dopo oltre 10 anni di attività e sviluppo Zarafa ha deciso che è arrivato il momento giusto per un nuovo nome ed un nuovo look anche per marcare il momento in cui il suo prodotto omonimo è stato rilasciato con un nuovo design e tante nuove funzionalità.

Kopano non è semplicemente una nuova identità, è anche una nuova piattaforma di comunicazione che è stata riscritta e modernizzata per competere con un nuovo mondo, come dicono alcuni, "Cloudificato".

Per alcuni, la convenienza di lavorare con applicazioni Cloud di terze parti, può anche essere soddisfacente ma una volta scoperto che Kopano offre la stessa convenienza ma aggiunge la libertà di integrare altre applicazioni, il pieno controllo sui propri dati e che costa meno di Office365 o G Apps allora il Cloud pubblico non ha più lo stesso appeal.

Zarafa WebApp 2.2

zarafa Communication PlatformZarafa WebApp 2.2 is out!

We have been following with excitement the development phases of Zarafa WebApp 2.2 as it has been a major (and long) effort to completely redesign the web interface that allows so many users to dispose of Microsoft Outlook.

At first sight WebApp 2.2 may look like a simple redesign of the graphical interface but in reality it's a complete rewrite that use modern frameworks and well documented API to facilitate customisation and integration with third party platforms.

Many improvements and new features have been added and a new plug-in architecture allows to create applets to add data and integrate with applications like SugarCRM, Twitter, Facebook and any other application that provides documented API and connectors.
