MUSCLE (Multi User Server Client Linking Environment) is an N-way messaging server and networking API. It includes client-side networking APIs for various languages, including C, C++, C#, Delphi, Java, and Python. MUSCLE lets programs communicate over a network via streams of serialized Message objects. The included server program ("muscled") lets its clients message each other and store information in its server-side hierarchical database. The database supports flexible queries via hierarchical wildcarding, and "live" updates via a subscription mechanism.
WordPress is a state-of-the-art, semantic, personal publishing platform with a focus on aesthetics, Web standards, and usability. It was born out of a desire for an elegant, well-architected personal publishing system. While primarily geared towards functioning as a Weblog, WordPress is also a flexible CMS capable of managing many types of Web sites. In addition to the basic blog functions, it also has an integrated link manager, categories, tags, custom taxonomies, file attachments, XFN support, support for stand-alone pages, Atom and RSS feeds for both content and comments, blogging API support (Atom Publishing Protocol, Blogger, MetaWeblog, and Movable Type APIs), spam blocking features, advanced cruft-free URL generation, a flexible theme system, and an advanced plugin API.

PHP Mobile Mail is aimed at mobile professionals who want to use their favorite MUAs (noteably pine or mutt) on their laptop, either in UNIX or Windows (under GNU Gygwin). This lets you work offline. It includes a mail_spooler program, which accepts the output of you MUA and spools (on, or offline). When connected, another process parses through the spool and sends your messages. It is also designed to "fake" using your REAL email address with free services like gmx.net, or mail.yahoo.com, when using their POP and SMTP servers, assuming you have a domain and account that you can control to this degree.
