jwma is a Web mail implementation based on the JSP Model 2 architecture. It builds on standard Java APIs (Java Mail API, Java Server Pages, and Java Servlet API) and relies on some available open source technologies (Xerces, Castor, Jakarta-ORO). jwma is designed and implemented for use with an IMAP server. It allows complete control over the store (creating, deleting, and moving folders, mailboxes, and messages). It supports MIME messages, supports text/plain message processing (e.g. making plaintext URLs "clickable"), and supports automatic sent & read mail archiving. It features a trash mailbox, includes a small addressbook, allows simple configuration of its features, and can be used in parallel with other mail clients (like Pine or Eudora).
