Free exchange server enterprise edition software for linux

SLAX Server Edition is a pocket operating system with many internet services ready to use. Includes DNS, DHCP, HTTP, FTP, MySQL, SMTP, POP3, IMAP and SSH.
SLAX is a small bootable CD containing the Linux operating system. SLAX distirbution runs Linux directly from the CD (or USB) without installing.
The Live CD described here is based on the Slackware Linux distribution and is downloadable from this website as an ISO image.
The primary goal of SLAX is to provide a wide collection of useful software while keeping the cds image small enough to be written to a 185 MB CD-R(W) medium (small 8 cm CD). SLAX boots directly from the CD or USB devices and it provides a full featured Linux operating system.
All your available partitions and data storage devices (CD-ROM, USB storage devices, etc.) should be recognized at boot and should be mounted to /mnt/xx. As an example, "disc0part1" may be assigned to the first partition on your primary hard drive, "disc1part1" for your USB storage device, or "cdrom0" for your CD-ROM drive. SLAX will never write anything to the mounted devices. Mounting is safe and does not change the data.
After booting, you should be able to login as a "root", with the password "toor"; both without quotes, of course.
Enhancements:
- fixed smb-kioslave in KDE so user can browse local windows shares
- this fix is also available as a separate module

Lineox Enterprise Linux distribution is based on source RPM packages from which Red Hat Enterprise Linux is compiled. Lineox Enterprise Linux contains all programs included in various Red Hat Enterprise Linux variations (Advanced Server (AS), Entry/Mid Server (ES), and Workstation (WS)).
It also contains programs included in separately sold Red Hat Cluster Suite and Red Hat Developer Suite. Lineox has removed and replaced all files of Red Hat Enterprise Linux which have restrictive copyright by Red Hat, Inc. Lineox has also tried to remove all user-visible references to Red Hat in Lineox Enterprise Linux.
The most notable difference between Lineox Enterprise Linux and Red Hat Enterprise Linux is the support options provided by Red Hat, Inc. Lineox, Inc. does not provide any support for Lineox Enterprise Linux with the base product.
Lineox, Inc. however plans to provide binary package updates for Lineox Enterprise Linux as long as Red Hat, Inc. provides updates for Red Hat Enterprise Linux in source package format.
Lineox has an automated system running on a cluster which builds new binary rpm packages as soon as new source code is available. New rpm packages are usually available in less than 12 hours after source code release.
After that Lineox builds Always Current Lineox Enterprise Linux disks automatically, but because of the time it takes to transfer the disk images to our web server, they are available from 2 to 12 hours after we release new packages.
Isnt Always Current Lineox Enterprise Linux untested or unreliable if it is released so often? Not really. We dont rebuild the installation environment, we just replace the installable packages with new ones.
You can even use same boot floppies or other boot media created for Lineox Enterprise Linux 4.0 to boot Always Current series Lineox Enterprise Linux. So Always Current Lineox Enterprise Linux is as tested and reliable as a system installed from "base release" and updated later. The only difference really is the work and time saved and the higher security right from the start.
Enhancements:
- Always Current Lineox Enterprise Linux 4.096 with Update 4 available. In the version 4.096 the installation environment is rebuilt, so it offers better hardware support during the installation. See the release notes for full information. The x86_64 release requires either AMD Opteron or Athlon64 CPU based computer. Some new Intel Xeon and Pentium IV processors with EM64T (Extended Memory 64 Technology) will also be able to run this version.

Linux is a UNIX like Operating System, famous for its reliability and security features, that runs on all kinds of computers. Linux was started by Linus Torwalds in 1991. The Linux Kernel and most applications it offers, are mostyl GPL licensed, called Open Source.
StartCom Enterprise Linux operating systems, are based on the RedHat Enterprise and Fedora source code each modified with reliability, security and efficiency in mind, to fit the tasks assigned to each flavor of StartCom Linux.

Enhancements:
- The newest StartCom Enterprise Linux AS-5.0.0 joins a series of successful and reliable operating systems build and distributed over the last three years by StartCom Ltd. This latest release provides full support for virtualization - the running of multiple instances of operating systems on one physical hardware unit. Depending on the installation preferences, AS-5.0.0 can function as server platform as well as advanced client workstation.
- StartCom Linux is using the latest in open source technology and with its known stability, reliability and security allows for mission-critical server deployments. The Global File System (GFS) provided in AS-5.0.0 allows the building and maintaining of high availability computer clusters, mainly used for data centers.
- The natural support of the XEN hypervisor, makes the running of multiple virtualized server instances possible. The benefits of server virtualization are consolidation, increased utilization, an ability to rapidly provision and start a virtual machine, and increased ability to dynamically respond to hardware failures by moving a virtual machine to different hardware.
- The enhanced usability of the desktop applications makes AS-5.0.0 also an excellent choice for client and development workstations. Many well known products such as Firefox, OpenOffice and Eclipse IDE are provided already during installation as possible options.
- StartCom Enterprise Linux AS-5.0.0 codenamed "Kishuf" is available for Intel i386 and AMD x86_64 architectures. DVD ISO images can be downloaded for free or ordered for a nominal fee. Alternative installation options via network or harddrive are also available.

Openchange project intends to provide an Open-Source implementation of Microsoft Exchange Server 2003 under Unix Platforms.
The Openchange Project is developed in C language under the BSD license, and will primary work on NetBSD, OpenBSD, FreeBSD and Linux platforms. The project time line has been defined to approximatively one year, and we believe the project will be in a complete stable state at this time.
Openchange wishes to integrate the enterprise working environment and to substitute to an Exchange Server in a transparent way, so final users may continue to use Outlook, or any other mail client.
We also intend to provide to network administrators an easy solution to migrate Exchange databases into Openchange ones and reversely. And last but not least, we work so developers may reuse our sources in a smart way.
The project is divided into 4 parts :
- The OpenChange Library
- The OpenReverse Library
- The Documentation Framework
- The Openchange specifications
The OpenChange Library
This library includes all the requests managing the identification process, the data flow, and all the other requirements needed to permit the communication between an Outlook client and an Exchange Server. It can be used either to develop another Exchange-like server or client.
The OpenReverse Library
Due to legal restriction, the Openchange Server wont reuse the Microsoft Jet Database file format. Instead, we provide a library making easy to parse headers, retrieve the data, calculate checksum and more generally to offer a abstract migration tool to other user defined backends. This library can also be used for basics to develop a repair database tool.
The Documentation Framework
In the documentation framework, you will find all our research results. The subjects may concern the Exchange Internals or treat of a related subject. We wants to provide the most valuable information so our work can be shared with developers community.
The OpenChange Specifications
At last, we will provide the complete specifications of OpenChange in a printable way. This major document of the OpenChange team will help new developers to understand how Exchange Server works, how we implemented our APIs to make OpenChange, Exchange compatible. Around this main development, you will find several modules:
- OpenUtils Library
- OpenSniff
- OpenEDB
Enhancements:
- This release fixes limitations from the previous release (0.2) and adds a set of new features.
- Sending email messages to external recipients is now possible.
- It can also fetch and create appointments, contacts, and tasks in their respective default folder.
- Experimental NEWMAIL notification support is also available.
- The openchangeclient command line messaging tool has been improved and exchange2mbox has been introduced.
- It provides a way to synchronize an Exchange mailbox with an mbox file, supports MIME types, and is able to reflect changes back to Exchange.

Enterprise File Exchange (EFX) slots in where email file attachment limits stop your users from sending those important files to a contact.

In the EFX world, the user visits the EFX site, uploads the file, enters the receivers email address and lets the system notify the receiver that theres a file waiting for them, via a simple email message.

Senders need to sign up, and the EFX system only allows transfers between internal users (those with addresses in an approved list) and external users, never external to external.

It is written in Python, using the Pylons framework.
