kmMail is a PHP-based mail program, based on the mail functionality of Keftamail and is being developed by current Kefta employees. It is meant to be a framework for putting a web-based mail program on your site, but is still robust enough to drop into your current site with little to no modification. The goals of kmMail are MIME compliance, speed, low overhead, and an enjoyable user interface.
JFetch is an application to download your email through protocols like POP3 and IMAP. The decision of whether to download a mail or not is made through a sequence of filters. By implementing certain interfaces, a user can very easily add his/her own filter to the current set of provided filters. Examples of filters are spam control, size restrictions, etc. JFetch downloads the email if it matches the criteria and then can deliver it using one of its delivery options.
Replex is an administrative tool for managing email on any Unix-like OS. It can handle multiple domains, users, mailing lists, etc. without requiring creation of Unix user accounts for mailboxes or authentication. Replex is written in PHP4 and stores all information in a MySQL database. Replex relies on Postfix for SMTP and Cyrus for IMAP and POP3 accounts.
Websieve Scripting Tool is a Perl CGI script that allows users to create complex Sieve syntax filtering rules, including a vacation response message, using a simple form on a Cyrus IMAP mail server. It also allows the setting of mailbox ACLs and password changes (LDAP and Qualcomm poppassd).
chk4mail lists the number of read and unread messages in all the folders in your mail directory and inbox. This is especially useful to people who automatically filter their mail to several folders. It supports standard mbox format, MMDF, MH, Maildir, and remote mail folders using IMAP.
Twiggi Web Based Groupware is a Web based groupware application, written in PHP4, using MySQL as its database engine. It was originally based on the excellent TWIG project. With many on-going enhancements, it is similar to Microsoft Outlook, and features the following modules: twiggi today, Mail, Contacts, Notes, ToDo, Bookmarks, and extensive online help (available in English and German). Twiggi has full language support for German, Dutch, Italian, and English.
Mail::Cclient is a Perl module and gives access to mailboxes in many different formats (including remote IMAP folders) via the c-client API. The c-client library is the core library used by Pine and the University of Washington IMAP daemon (written by Mark Crispin). Sort, search, threading, and the SMTP API are supported.
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.
