GBuffy will poll multiple mailboxes for new mail. It will list the number of new messages in each mailbox you configure. It will also highlight the mailboxes that have new mail, and you can display the message headers by pressing mouse button one on a mailbox. GBuffy is currently capable of watching MBOX, MMDF, Maildir and MH Folders. This version also supports IMAP4rev1 and NNTP with XOVER mailboxes, as well as displaying X-Face headers.
Gnus is an extremely powerful, configurable news and mail reader written in Emacs LISP for GNU Emacs and XEmacs. It provides threading, sorting, and article scoring; can retrieve messages via NNTP, local news or mail spool files, IMAP, POP, and other methods; and has features that make it efficient for reading news over low-speed network connections.
INN (InterNetNews) is an extremely flexible and configurable Usenet / netnews news server. It supports accepting articles via either NNTP connections or via UUCP, as well as serving out articles to reading clients via NNTP. It supports multiple different ways of sending outgoing articles to other hosts, as well as multiple different storage mechanisms for articles and article overview information via internal APIs. Compared to other news servers, INN is more complicated with a steeper learning curve, but is extremely flexible and configurable, comes with a large suite of supporting programs, and supports embedded filters in either Perl or Python.
JFreshmeat-NNTP is the first released mini-app to use an NNTP class being developed for a Java-only NNTP-based newsreader. It connects to freshmeat's NNTP server, and retrieves the headers, displaying them in the top pane of a two-pane window. Double-clicking on a particular announcement will retrieve the text of that announcement and display it in the bottom pane. The initial class is very short, calling a general purpose newsgroup monitor class. It can be adapted to monitor any server/group very easily. Future plans for the JFreshmeat-NNTP code include SOCKS support, saving article data, persistant storage of articles, UI improvements, timed polling for monitoring updates. It may also be rolled into the general purpose newsreader as a side-feature eventually.
Leafnode is a news server, suitable for small, limited-bandwidth sites with only a few users (and useful for offline news reading). Leafnode keeps track of which groups are being read and downloads only articles in those groups. Leafnode has been designed to require no maintenance and to be easy to set up.
mail2news-easy is a utility that converts mail to news and news to mail. This program is unique in that it needs less configuration and modifying files than other products; it needs only one file, containing the signature of the mailing-list sender and the news name to which it relates. It installs easily, suppressing 100 of 100 modifications in the first install, and 75 of 100 when upgrading.
The SeaMonkey project is a community effort to develop an all-in-one Internet application suite. It contains an Internet browser, email and newsgroup client with an included Web feed reader, HTML editor, IRC chat, and Web development tools, and is sure to appeal to advanced users, Web developers, and corporate users. It uses much of the Mozilla source code powering such successful siblings as Firefox, Thunderbird, Camino, Sunbird, and Miro.
