Postman is a high performance web based IMAP and NNTP client

Postman is a full featured IMAP and NNTP client written in C/C++ at the Computer Science Service of the University of Valencia.

The system has two components, a small cgi program called from the web server and a dedicated daemon that controls the connections to the IMAP and NNTP servers for each user session. Designed with high performance in mind, it supports hundreds of concurrent user sessions without a hitch.

Postman is skinnable, has multilanguage support (currently Catalan, English, Spanish and Basque) and uses simple HTML (with optional javascript) so it can be used with any browser. From version 3.0 it is CSS based and has full UTF-8 support.

Besides, the client allows searching and sorting in mailboxes, send and receive multiple attatchments, the use of multiple mailboxes per user and the definition of user addressbooks and signatures (using files or DB databases instead of a full DBMS as other WebMail clients do).
