BEJY is a modular server application. It is packaged, by default, as a Web application container and mail server with SSL. It has functionality similar to inetd, and has some helper classes/functions to ease the implementation of new protocols. It provides a generic multithreaded TPC/IP server implementation with optional SSL support, covering the complete connection and thread management. Each supported service provides its protocol implementation. The current version comes with HTTP, SMTP, POP3, and IMAP protocol implementations. The HTTP protocol implementation also contains a servlet engine, a JSP 1.2 engine, a handler to invoke CGI, and other useful things. The mail protocols require a database using JDBC, as MySQL, MSSQL, and others.
sTeam provides a technical platform which allows groups of students, lecturers, and any other groups to construct and arrange their individual and cooperative learning and working space. It consists of an object-oriented server connected to a database, and Web, Java, and other (FTP, SMTP, IRC, etc.) clients. The server is event-driven and manages all user objects as well as the communication between the connected clients. Features that were different from most other cooperation tools is the self-organisation and self-administration by the members within the virtual environment.
GatorMail is a Java Servlet-based Webmail application built on the Jakarta 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 and simple, user-friendly interface are the primary goals of the project.
Zimbra is a next-generation enterprise messaging and collaboration system. It features an Ajax Web client with conversation views, fast email search, Web service mash-ups, shared calendars, document authoring, and IM. The server also syncs to MS Outlook (via MAPI), the Apple desktop (via iSync, iCal, and CalDAV), POP/IMAP clients, and mobile devices (BlackBerry, smart phones, HTML Web browsers). A version of the Web client, Zimbra Desktop, also works offline with any POP/IMAP server. Administrators can control live backup/restores of individual or groups of mailboxes, hierarchical storage (HSM) and clustering, LDAP directory configuration, Web services integration with existing enterprise applications, and integrated anti-spam and anti-virus.
