Innovating within the email server industry since 1998, Calacode develops @Mail, a robust integration of Open Source Technology, Unix, Strong Encryption, and industry-standard Groupware Features in a centralized messaging platform.

The software can be used as a WebMail interface to an existing mailserver, a complete Email Server platform, or an Exchange replacement.

Zimbra™ Collaboration Suite Open Source Project Beta Launch

Zimbra is a community for building and maintaining next generation collaboration technology. Currently, this technology is available as a beta version. At Zimbra, our goal is to make e-mail, calendar, contacts and other communications technologies the best they can be. We believe that by opening the technology to the community we will ensure that we can maximize innovation, scale and the ability to co-exist with existing messaging systems.

CooooooooL!

What is the key benefit of Microsoft Domain Security?

In a word, single sign-on, or SSO for short. To many, this is the Holy Grail of MS Windows NT and beyond networking. SSO allows users in a well-designed network to log onto any workstation that is a member of the domain that contains their user account (or in a domain that has an appropriate trust relationship with the domain they are visiting) and they will be able to log onto the network and access resources (shares, files, and printers) as if they are sitting at their home (personal) workstation. This is a feature of the domain security protocols.

Samba HOWTO Chapter 4. Domain Control

Open-source Samba turns a Unix or Linux system into a file and print server for Microsoft Windows network clients. Tom Syroid dishes up a juicy tutorial that shows you how to configure Samba as the primary domain controller on an xSeries server.

Using Samba as a primary domain controller

This document describes how to setup Samba on a Debian GNU/Linux file server to act as a primary domain controller for Windows 2000 workstations.

Secure Shell (SSH) is open, free, fast, secure, and easy to setup (once you know how).

O'Reilly Network: Using SSH Tunneling

Zebedee is a simple program to establish an encrypted, compressed “tunnel” for TCP/IP or UDP data transfer between two systems. This allows traffic such as telnet, ftp and X to be protected from snooping as well as potentially gaining performance over low-bandwidth networks from compression.

The main goals for Zebedee are to:

Provide full client and server functionality under both UNIX/Linux and Windows.

Be easy to install, use and maintain with little or no configuration required.

Have a small footprint, low wire protocol overhead and give significant traffic reduction by the use of compression.

Use only algorithms that are either unpatented or for which the patent has expired.

Be entirely free for commercial or non-commercial use and distributed under the term of the GNU General Public Licence.

Of course, Zebedee is by no means the first, or only secure tunnel program available. It does not pretend to compete with the likes of ssh, SSL or FreeS/WAN in terms of breadth of function but if you want something quick, simple and completely free then it may be the tool for you.

Possibly swell for getting lawyers filesharing and IM through firewalled courtrooms.

Zebedee: Secure IP Tunnel

httptunnel creates a bidirectional virtual data connection tunnelled in HTTP requests. The HTTP requests can be sent via an HTTP proxy if so desired.

This can be useful for users behind restrictive firewalls. If WWW access is allowed through a HTTP proxy, it's possible to use httptunnel and, say, telnet or PPP to connect to a computer outside the firewall.

What are the benefits of Office XML Formats?

A.

The new Office XML Formats introduce a number of benefits not only for developers and the solutions they build, but also for individual users and organizations of all sizes.

Integration of Business Information with Documents
Office XML Formats enable rapid creation of documents from disparate data sources, accelerating document assembly, data mining, and content reuse. Exchanging data between Microsoft Office applications and enterprise business systems is simplified—alter information inside a Microsoft Office document or create a document from scratch using standard tools and technologies; access to Microsoft Office applications is not required. Employees can improve productivity by publishing, searching, and reusing information more quickly and accurately in the environment they choose.

Open and Royalty-free Specification
Office XML Formats are based on industry standard XML and ZIP technologies, support full integration by any technology provider, and are available via a royalty-free license. Format specifications will be published and made available under the same royalty-free license that exists for the Microsoft Office 2003 Reference Schemas—openly offered and available for broad industry use.

Compact, Robust File Format
Smaller file sizes and improved recovery of corrupted documents enable Microsoft Office users to operate efficiently and confidently and reduces the risk of lost information. Office XML Formats use ZIP and compression technologies to store documents offering potential cost savings as it reduces the disk space required to store files and decreases the bandwidth needed to transport files by e-mail, over networks, and across the Web.
