Open Source web mail

1. Open Web Mail Project
   Open WebMail is a webmail system based on the Neomail version 1.14 from Ernie Miller. Open WebMail is designed to manage very large mail folder files in a memory efficient way. It also provides a range of features to help users migrate smoothly from Microsoft Outlook to Open WebMail.Open WebMail project is an open source effort made possible thanks to volunteer contributions by hundreds of developers around the world. But volunteers can't do everything: it takes money to host our server and coordinate the work done by volunteer contributors.
   Please make a donation if you enjoy using our software and believe in the importance of what the Open WebMail project is working to accomplish.
       
2. Open Source Web Mail Clients in Java
   WebMail is a www-frontend to IMAP/POP3 mailboxes. You can compare it to the systems Hotmail, YahooMail etc use. It allows a user to access his mailbox via the world wide web and do most things other mail programs allow to do, even if he is not sitting on his own personal computer or corporate LAN. Primarily jwma is a WebMail implementation in Java, enabling the user to access, manage and compose email using a standard web browser. GatorMail is a servlet-based Webmail built on the Struts framework. It was originally developed to meet the needs of the University of Florida. Efficient interaction with the mail store along with a low support overhead are the goals of the project.
     
3. OpenSource ASP.NET webmail application written in C#
   SharpWebMail is an ASP.NET webmail application that is written in C#. It uses a POP3 or IMAP servers as the mailstore and sends mail through a SMTP server. It is very simple to configure (only a few settings in the web.config file). You can compose HTML messages, search your inbox, read complex mime messages, have multiple address books and much more. Features:
   * Very simple to configure (only a few settings in web.config).
   * Multiple POP3 and IMAP servers can be configured to read mail from. The selection of the server is based in login (username) information or (optionally) by the user.
   * Tries to minimize the queries to the server caching message info (only headers).
   * Authentication is handled by your email server (no additional databases needed).
   * Sends mail through a SMTP server (chosen from the login information of your users). Including support for SMTP AUTH.
      
4. Open Source AJAX Webmail
   It seems AJAX webmail is all the craze. Right on the heels of both Microsoft and Yahoo launching beta versions of their new AJAX webmail clients, an Open Source startup RoundCube has released an alpha of a GPLed AJAX webmail client. While there are still many features missing (like search!), the demo they have is completely cross-browser compliant and overall very impressive.RoundCube Webmail is a browser-based multilingual IMAP client with an application-like user interface. It provides full functionality you expect from an e-mail client, including MIME support, address book, folder manipulation and message filters. RoundCube Webmail is written in PHP and requires the MySQL database. The user interface is fully skinnable using XHTML and CSS 2.
   
   
5. Open-source Web software
   The tech giant announced a partnership with Zend Technologies to create a bundle called Zend Core, which includes IBM's Cloudscape-embedded database and Zend's PHP development tools. Zend sells tools built on the open-source edition of PHP and offers related services. The two companies intend to devote programmers to make PHP work better with corporate databases and Web services protocols. IBM also plans to establish an area dedicated to PHP on its developer Web site, which will include technical resources such as white papers. Zend Core will be available as a free download in the second half of the year. PHP, originally known as Personal Home Page, is a widely used scripting language for generating Web pages. Unlike compiled languages such as Java or C, scripting languages like PHP are easier to learn. They are generally used for simpler tasks, rather than for complex number-crunching jobs.

7. New Web Mail: More Polished, Powerful
   Microsoft and Yahoo are poised to make Web-based e-mail more powerful than ever with updates that bring a desktop-style interface to their respective Web mail offerings. We tested betas (currently invitation-only) of Windows Live Mail and Yahoo Mail, and also looked at an open-source newcomer called Zimbra. All three apps use an increasingly popular programming technique called Ajax (Asynchronous JavaScript and XML) to improve on standard Web mail and even Google's Gmail. As Ajax applications, the mail clients we tested can preload information and update their displays on the fly. So when you open up an e-mail message, you'll see it immediately, rather than having to wait for it to download. And when you delete a message, the application can update instantly, even though the delete request is still being processed in the background.
     
8. Zimbra: More Than Just Web Mail
   AJAX is growing in popularity as a powerful JavaScript-based mechanism for client-server communication and the creation of dynamic, interactive, browser-based Web applications. Zimbra is a new groupware platform that centers around a robust AJAX-based Web client that has features missing in some desktop groupware applications. This article provides a brief overview of Zimbra. I have been trawling the Internet looking for robust, practical, effective examples of AJAX in action. Recently I came across Zimbra, which provides an intriguing example of what can be achieved with AJAX as well as an example of the type of sophisticated application which can be built through corporate open source development. Zimbra is a complete, collaborative groupware platform available in its base form as an open source product. One of its unique features is an AJAX-based web mail front-end designed to be the primary point of access for Zimbra users. 
      
9. Open source web 2.0 webmail
   With the advent of gmail, and yahoo's new webmail client based on oddpost we've seen the creation of second generation webmail. This is good because the existing solutions suck. But as any good freedom loving hacker might ask, kellan wants to know where are the free / open source alternatives? Most of the options such as squirrl mail and IMP are functional but they feel years out of date in-comparison to gmail and oddpost. Well now there appears to be a viable alternative in zimbra (via ajaxian). It's licensed under a modified version of the MPL. I wonder if folks like riseup and resist.ca will try it out and offer it to their users. To me radical activist email services need to start adopting more advanced tools to compete with the big boys such as yahoo and gmail. I suppose hotmail will be coming out with a big revision at some point as well.

11. Free open-source SMTP/POP3 email for Windows
    Many people who use Windows Small Business Server (SBS) 2003 are dismayed by the lack of a SMTP/POP3 server in the standard edition. If they want full email functionality, they have to install Exchange Server, which is a lot more than many shops need if they're managing just a few basic mailboxes. I've looked at some simple free/open-source SMTP/POP3 solutions for Windows in the past. Among them was XMail, but I became very discouraged after working with it, because it was difficult to configure and manage. A much better, more polished and Windows-specific implementation of a no-cost email server is hMailServer 4.2. In addition to being free and open-source, it's easy to set up and work with, and presents users with a GUI-based manager (as opposed to XMail's plethora of configuration files). 
     
12. Open Source E-mail Security
    In this book you'll learn the technology underlying secure e-mail systems, from the protocols involved to the open source software packages used to implement e-mail security. This book explains the secure MIME (S/MIME) protocol and how it is used to protect data transmitted across the Internet. It also explains the concepts crucial to stopping spam messages using the three most popular open source mail packages--sendmail, qmail, and postfix. It presents detailed configurations showing how to avoid accepting messages from known open relays and how to filter known spam messages. Advanced security topics are also covered, such as how to install and implement virus scanning software on the mail server, how to use SMTP authentication software, and how to use the SSL protocol to secure POP, IMAP, and WebMail servers.
