Free microsoft exchange software for linux

WebGrab is a tool that acts as a CGI proxy. It simulates a Web browser and grabs data from external programs, and can exchange individual words or whole blocks.

The project can be run standalone or in conjunction with phpCMS.

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.

MailArchiva is a powerful email archiving solution. MailArchiva project is all you need to ensure that your organizations emails are backed up permanently. It automatically retrieves emails from Microsoft Exchange and stores them on multiple hard disks.
MailArchiva stores all incoming, outgoing, and internal emails for long-term storage. In doing so, it enables your company to retain valuable knowledge and comply with US and EU legislation such as the Sarbanes Oxley Act.
MailArchiva ensures that the integrity of your information remains intact. Emails are stored directly on the filesystem, as opposed to a database. As a result, there are no hidden database maintenance costs and the integrity of archived information is not subject to database corruption.
MailArchiva is a turnkey product that is easy to install and use. A clean install usually takes approximately 30 minutes.
MailArchiva is a commercially supported open source product. You have the assurance of commercial grade support combined with open source benefits.
Enhancements:
- This release introduces several major enhancements and bugfixes.
- For instance, MailArchiva is now fully internationalized, supporting indexing, search, and retrieval of emails in multiple languages.
- The archiving server has been completely rearchitected to utilize Java 1.6 contructs.
- The Microsoft Exchange archiving agent has been redesigned from the ground up.

Fetchmail is a full-featured, robust, well-documented remote-mail retrieval and forwarding utility intended to be used over on-demand TCP/IP links (such as SLIP or PPP connections). Fetchmail supports every remote-mail protocol now in use on the Internet: POP2, POP3, RPOP, APOP, KPOP, all flavors of IMAP, ETRN, and ODMR. It can even support IPv6 and IPSEC.
Fetchmail retrieves mail from remote mail servers and forwards it via SMTP, so it can then be read by normal mail user agents such as mutt, elm(1) or BSD Mail. It allows all your system MTAs filtering, forwarding, and aliasing facilities to work just as they would on normal mail.
Fetchmail offers better security than any other Unix remote-mail client. It supports APOP, KPOP, OTP, Compuserve RPA, Microsoft NTLM, and IMAP RFC1731 encrypted authentication methods including CRAM-MD5 to avoid sending passwords en clair. It can be configured to support end-to-end encryption via tunneling with ssh, the Secure Shell.
Fetchmail can be used as a POP/IMAP-to-SMTP gateway for an entire DNS domain, collecting mail from a single drop box on an ISP and SMTP-forwarding it based on header addresses. (We dont really recommend this, though, as it may lose important envelope-header information. ETRN or a UUCP connection is better.)
Fetchmail can be started automatically and silently as a system daemon at boot time. When running in this mode with a short poll interval, it is pretty hard for anyone to tell that the incoming mail link is not a full-time "push" connection.
Fetchmail is easy to configure. You can edit its dotfile directly, or use the interactive GUI configurator (fetchmailconf) supplied with the fetchmail distribution. It is also directly supported in linuxconf versions 1.16r8 and later.
Fetchmail is fast and lightweight. It packs all its standard features (POP3, IMAP, and ETRN support) in 196K of core on a Pentium under Linux.
Fetchmail is open-source software. The openness of the sources is your strongest possible assurance of quality and reliability.
Main features:
- STARTTLS is supported in both POP and IMAP.
- ESMTP AUTH (RFC 2554) is supported.
- Has the capability of adding trace information to the Received header to faciliate mail filtering by mailserver and remote account.
- Fetchmail now has options to handle SSL certificate validation.
- Fetchmail can be told to fall back to delivering via local sendmail if it cant open port 25.
- Support for AUTH=CRAM-MD5 under POP3, a la RFC2195.
- Support for ODMR (On-Demand Mail Relay), RFC 2645.
- Its now easy to deliver mail to a local LMTP socket.
- The interface option now checks both local and remote interface IPs.
- The plugin facility has been enhanced; %h and %p options are now available to pass in the hostname and service port number.
- Added a dropdelivered option to discard Delivered-To headers. This addresses a problem with using fetchmail and postfix as a relay inside a domain; when postfix sees incoming messages with delivered-to headers looking exactly the same as the ones it adds himself, it bounces the message.
- Added --smtpname to set username and domain portion of SMTP "RCPT TO" command. - Added "from" servers IP address to inserted Received line.
- Fetchmail now runs on BeOS, thanks to David Reid .
- In IMAP, unseen-message counting and indexing is now done by SEARCH UNSEEN at the beginning of each poll or re-poll (rather than with the UNSEEN and RECENT responses and FLAGS queries on individual messages). This significantly cuts down on traffic to and from the server, and gives more reliable results.
- The aka option now matches hostname suffixes, so (for example) saying `aka netaxs.com will match not just netaxs.com but also (say) pop3.netaxs.com and mail.netaxs.com.
- Fetchmail can optionally use the RFC 2177 IDLE extension on an IMAP server that supports it. On IMAP servers that dont, it can simulate it using periodic NOOP commands.
- Fetchmail now recognizes the RFC 2449 extended responses [IN-USE] and [LOGIN-DELAY].
- Fetchmail running in daemon mode now restarts itself quietly when the rc file is touched.
- Following recent court decisions and changes in U.S. federal regulatory policy, hooks for Secure Sockets Layer (SSL) are now part of the main fetchmail distribution. The distribution still contains no actual cryptographic code.
- NTLM support under IMAP, so fetchmail can query Microsoft Exchange servers.
- Expunge option can now be used to break POP3 retrieval into subsessions.
- Support for AUTH=CRAM-MD5 under IMAP, a la RFC2195.

Vista Basic provides a theme similar to Microsoft Vista.
